CCTV unveiled the current situation of genetically modified rice in the market.

　　 In April this year, the reporter randomly bought five bags of different varieties of rice in a large supermarket in Wuhan, Hubei Province, and then sent them to the China Academy of Inspection and Quarantine for testing. The test results are surprising. Among the five kinds of rice, three contain genetically modified ingredients. So far, the government of China has never approved the commercial cultivation of any kind of genetically modified rice, nor has it approved the import of genetically modified rice, which means that the genetically modified rice and rice products appearing in the market are illegal, and these illegal genetically modified products are quietly coming to people’s table.

　　 Transgenic component Bt63 was detected in the rice purchased in the supermarket.

　　 In recent years, there have been media reports that the rice sold in the surrounding markets in Wuhan, Hubei Province contains genetically modified ingredients. At the same time, rice products exported from China to the European Union are frequently found to contain genetically modified ingredients. In the EU’s rapid warning system for food and feed, in 2013 alone, rice products exported from China to the EU were found to contain genetically modified ingredients for 25 times.

　　 In April this year, the reporter bought five kinds of rice at random in a large supermarket in Wuhan, and then sent them to China Academy of Inspection and Quarantine for testing. The test results are surprising. Among the five kinds of rice, three contain the genetically modified ingredient Bt63, and most of the genetically modified ingredients displayed in the EU early warning system are of this type.

　　 Bt63 is a patented transgenic insect-resistant rice developed by the School of Life Science and Technology of Huazhong Agricultural University. It was successfully developed in 1999 and has been evaluated for 11 years. In 2009, Bt63 transgenic insect-resistant rice obtained the safety certificate of transgenic organisms, but it was not approved for commercial planting. According to "People’s Republic of China (PRC) Seed Law", genetically modified crops are not allowed to be planted commercially before obtaining the commercial planting license. Then, where did the rice containing Bt63 gene detected in the market come from, where was it planted, and where did the seeds come from?

　　 A kilo of rice is planted in 40 yuan, and many farmers grow insect-resistant rice.

　　 Zhongshan Road, Wuchang District, Wuhan City is a famous seed street, where dozens of seed sales outlets, large and small, are concentrated. In April this year, during the rice planting season, the reporter came to this street, trying to find genetically modified rice seeds and then tracing their sources.

　　 I heard that the reporter wanted to buy insect-resistant rice, but the owners of several shops said that they didn’t. When asked why, they said that they had sold it before, but now it is strictly controlled and no one dares to sell it.

　　 After repeated questioning by reporters, a boss provided clues. According to this, the reporter went to Jinxing Village of Lingmiao in Jiangxia section for investigation, and found that many local farmers were planting genetically modified rice. They buy rice seeds at the seed sales point in Jinxing Village at the price of one catty in 40 yuan, but they usually buy rice seeds through acquaintances. For various reasons, the boss of the point of sale avoided the reporter’s interview.

　　 The source of transgenic rice seeds may be Huazhong Agricultural University.

　　 Bt63 transgenic insect-resistant rice is a patent of School of Life Science and Technology, Huazhong Agricultural University. Theoretically, Huanong is the original seed source of all the transgenic rice containing Bt63 in the market.

　　 Zhang Qifa, academician of Chinese Academy of Sciences, professor of Huanong College of Life Science, mainly engaged in molecular genetics and genetic engineering research, and the leader of Bt63 transgenic insect-resistant rice project. In the interview, Zhang Qifa did not deny the possibility of GM rice spreading from Huanong. According to him, there may be two channels: first, different units or individuals may take rice seeds when the results are displayed and identified in 1999; Second, when Huanong conducted a large-scale productive experiment in 2003, a subsidiary may illegally breed after taking the seeds.

　　 According to Zhang Qifa, in the 1990s, the state did not have strict legal provisions on the safety management of genetically modified organisms, and many scientific research achievements were shared by everyone. It was not until 2001 that the State Council issued and implemented the Measures for the Safety Management of Agricultural Genetically Modified Organisms that the safety management of genetically modified crops became standardized. Prior to this, seed companies could easily get Bt63 transgenic insect-resistant rice seeds, then breed them themselves and then enter the market.

　　 According to several media reports, Zhang Qifa was the CEO of a company named corneal, which was the important source of Huanong’s "intentional disclosure" of genetically modified rice.

　　 In this regard, Zhang Qifa said, "It is hard to say that it was intentionally leaked". At that time, the establishment of the company was a part of the country’s plan to promote the cultivation and industrialization of genetically modified crops. He introduced that according to the national regulations on the management of genetically modified crops, large-scale productive experiments must be carried out before genetically modified insect-resistant rice can obtain a biosafety certificate. In 2003, the Ministry of Agriculture approved 2,000 mu of farmland for the production test of Bt63 transgenic insect-resistant rice, in which hundreds of farmers participated. At the end of 2002, after the establishment of corneal Company, the production experiment of Bt63 transgenic insect-resistant rice was just completed.

　　 So, in the process of productive experiment, did it cause the leakage and diffusion of seeds? According to Zhang Qifa, corneal Company didn’t have seed production capacity at that time, but entrusted other seed companies to produce seeds, and then distributed the seeds to farmers after recycling them. In this process, the seed company has the possibility of leakage.

　　 The shopkeeper tore up the receipt and denied selling genetically modified rice seeds.

　　 The reporter went to Wulijie Town, Jiangxia District, Wuhan, which is also a major rice producing area. According to the interview experience in Duanlingmiao town, it is difficult for strangers to buy genetically modified rice seeds, so the reporter found a local farmer to help him buy them at the seed sales point in the town.

　　 According to the farmer, this kind of insect-resistant rice is very popular among farmers, because it can resist borers, and they can save the money for buying pesticides and the labor cost for spraying drugs, saving 200 to 300 yuan per mu, which is quite attractive to farmers with a gross income of only over 1000 yuan per mu.

　　 There are nearly ten seed shops in Wulijie town, large and small, and the farmers who help them enter a sales point called Jiexing Seed Shop. A few minutes later, the boss turned into the back room and took out two bags of genetically modified insect-resistant rice seeds. However, when the reporter entered the salesroom again, the proprietress said that she never sold genetically modified insect-resistant rice seeds.

　　 Subsequently, the reporter sent the purchased rice seeds to Beijing Entry-Exit Inspection and Quarantine Bureau for testing, and the results showed that the rice seeds contained insect-resistant transgenic Bt63. According to the information on the packaging of the rice seed named "Liangyou Jianghui 902" purchased by the reporter, the rice seed was produced by Hunan Xiuhua Technology Co., Ltd. The reporter went to Xiuhua Company in Zhuzhou City, Hunan Province, and found Li Yonghong, the person in charge of declaring the variety at that time, but he said that the company could not have genetically modified seeds.

　　 With the assistance of Zhuzhou Seed Management Station, the reporter sampled the seeds of Liangyou Jianghui 902 on the spot. The test results showed that the sampled grains did not contain Bt63. That is to say, the seeds purchased by the reporter in the seed sales department in Jiangxia District of Wuhan and the seeds in the grain depot of Hunan Xiuhua Company are not the same rice seed.

　　 Then, who produced the genetically modified rice seeds purchased by reporters and how did they enter the market? The reporter once again came to Jiexing Seed Sales Department. The proprietress denied that she had ever sold rice seeds, so the reporter took out the receipt issued by the sales department when she bought rice seeds, but the proprietress always denied it. Under the stalemate, the reporter dialed the complaint phone number of Jiangxia Seed Station marked on the receipt, hoping that law enforcement officers could come to investigate and collect evidence, but the person who answered the phone said that the leaders had a meeting and the law enforcement officers had gone to the countryside and could not come.

　　 No sooner had the reporter put down the phone than the owner of this shop appeared. After a dispute, the boss tore up the receipt and drove the reporter away.

　　 Rice testing loopholes, factory inspection, genetically modified

　　 Among the three kinds of rice bought by the reporter that were found to contain transgenes, two kinds of rice were produced at Shekou Street in the urban-rural junction of huangpi district.

　　 According to Director Ni of a rice factory, the rice provided by the reporter should come from Jianghan Plain, such as Qianjiang, Jingmen and Jingzhou. The rice and rice in their processing plant come from all over the country. During the processing, the factory will make certain preparations according to the taste and color of the rice, and then pack it and leave the factory.

　　 In the test report presented by director Ni, the reporter saw that the rice in Wuhan market is currently implemented in GB1354-2009 standard. The standard only stipulates some physical indicators of rice. After the local regulatory authorities test rice according to this standard, qualified rice can enter the market for sale.

　　 It is understood that the rice factory standards formulated in China do not contain genetically modified detection items, so government regulatory authorities and enterprises will not test the rice factory, which leads to rice manufacturers not knowing even if some rice contains genetically modified ingredients. These rice, so quietly to the consumer’s table.

　　 For many export enterprises, they also face the same problem, because they unknowingly bought rice containing genetically modified ingredients, which caused them to suffer losses when exporting. A batch of white rice cakes exported by a food company in Shanghai to the European Union in 2013 were found to contain genetically modified ingredients.

　　 In order to reduce losses, some domestic enterprises will conduct their own testing of genetically modified ingredients according to EU standards. However, the general manager of a food company in Shanghai said that because there are many sources of rice in the market, despite the testing links, enterprises are hard to prevent. According to what they know, genetically modified rice has spread, and it is difficult to recover it, and it is out of control. Most of the rice in Hunan, Hubei, Anhui and Fujian have been "polluted" by genetic modification.

　　 It is understood that on May 27 this year, the Ministry of Agriculture issued the Notice of the Ministry of Agriculture on Further Strengthening the Safety Supervision of Agricultural Genetically Modified Organisms, requiring agricultural departments at all levels to focus on rice, corn, soybean and rape seeds and severely investigate and deal with illegal production, processing and sales of genetically modified seeds according to law.

A comprehensive breakthrough in ＂localization＂

Under the leadership of Su Yongqiang, Shen Gu survived the most difficult stage in history and finally turned the corner.

In January 2006, at the national science and technology conference, the national leaders formally put forward the policy of "independent innovation". A month later, the State Council issued "Several Opinions on Accelerating the Revitalization of Equipment Manufacturing Industry" (the State Council No.8 Document in 2006), which proposed that "we should select a number of major technical equipment and products that have an important impact on national economic security and national defense construction, have a significant effect on promoting the sustainable development of the national economy, have a positive driving role in structural adjustment and industrial upgrading, and can expand the market share of independent equipment as soon as possible, and increase policy support and guidance to achieve major breakthroughs in key areas."

Among the 16 key breakthrough areas listed in this document, two are directly related to Shengu, namely, the localization of large-scale ethylene complete sets of equipment of one million tons and the research and development of large-scale coal chemical complete sets of equipment. The transformation of the country’s major policies has provided conditions for the all-round breakthrough of Shen Gu.

"Localization" has finally entered the room.

While China’s 300,000-ton ethylene equipment has not been made in China, the international ethylene equipment continues to develop to a large scale, and a million-ton ethylene plant was built in the second half of 1990s. After entering the 21st century, China has also built three million-ton ethylene projects with the international trend, namely, the 900,000-ton ethylene project of Shanghai Secco Petrochemical Co., Ltd., the 800,000-ton/year ethylene project of China Shipping Shell, the 10,000-ton oil refining project of Dushanzi Petrochemical Company of PetroChina and the 1,000-ton ethylene project. However, they all did not use domestic main equipment because of joint ventures and other reasons.

At that time, excessive dependence on imported equipment has become a stumbling block to the development of petrochemical industry in China. In a report to the National Development and Reform Commission, Sinopec wrote: "In recent years, the shortage of international special equipment and materials resources has brought great pressure on the supply of equipment in the domestic petrochemical industry. For example, the supply of large-scale units such as ethylene’ three machines’ (cracking gas compressor, propylene compressor and ethylene compressor) is very tight in the global market, and some foreign manufacturers often do not respond to domestic inquiries. The delivery time has been extended from 12 months in 2003 to 22-24 months in 2007, and the price has nearly doubled. "[1].

Obviously, if the equipment is not localized, the petrochemical industry in China, which has entered a high-growth track, will be curbed.

The first self-built million-ton ethylene project in China was the 1 million-ton/year ethylene reconstruction and expansion project of Maoming Petrochemical Company, which was formally started in December 2004 and completed in September 2006. It was based on the 360,000-ton/year ethylene project of Maoming Petrochemical Company. According to the report on the website of SASAC, "448 of the total 510 cracking units in the project are made in China, and the localization rate of the equipment is 87.8%. Not only the new technology of ethylene cracking and ethylene recovery jointly developed by China Petrochemical and Rhuems Company of the United States is adopted, but also some core equipment such as ethylene cracking gas compressor and cold box are localized." [2] The cracked gas compressor mentioned in this report is provided by Shen Gu, but at the enterprise level, the actual situation is not so "politically correct".

When Maoming Petrochemical signed a contract with Shen Gu, the venue ready for signing had been arranged. The boss in charge of technology of the other party took Su Yongqiang and said, let’s have a talk outside. Su Yongqiang asked him, "We have to sign this time. What’s your attitude now?" The other party said, "I still agree to import." When Sue asked why, he said, "Manager Su, you have to understand me. I know that you are capable and you can do well, but if you say it from my mouth, my head will be smashed." Most of the risks are understood, and the deeper reasons are not mentioned. You can sign if you have the ability, and I will serve you if you sign. " Su Yongqiang said he would sign it right away, but he still didn’t believe it. Of course, Su Yongqiang signed it-"Maybe I’m a competitive person, and I have to do what I can’t do."

Su Yongqiang.

The major turning point of "localization" is the establishment of the national policy of independent innovation. In June, 2006, according to "Several Opinions on Accelerating the Revitalization of Equipment Manufacturing Industry", the million-ton large-scale ethylene complete equipment was listed as the key point of localization by the National Development and Reform Commission. At that time, the localization rate of ethylene plant, PTA complete sets of technical equipment and natural gas long-distance pipeline equipment was required to be not less than 75%.

In this context, China decided to invest 20 billion yuan in Tianjin, Zhenhai and Fushun to build three million-ton ethylene projects, and gave Shengu Group the task of supporting "three units". However, to be on the safe side, the million-ton ethylene "three machines" developed by Shengu for the first time were not put into the same project, but were respectively assigned to three million-ton ethylene plants, namely, Sinopec Tianjin Petrochemical used cracking gas compressor, Sinopec Zhenhai Refining and Chemical Company used propylene compressor, and Fushun Petrochemical Company under PetroChina used ethylene compressor.

When Su Yongqiang took the "Shangfang Sword" (that is, the task assigned by the government department) to find the main leaders of the party group of big users, they still said that it was best to ask Zhang Guobao, deputy director of the National Development and Reform Commission, to sign it. Su Yongqiang still remembers what Zhang Guobao said to him: Lao Su, I am the deputy director of the National Development and Reform Commission, and I have never signed for the enterprise. But you are special, and you are promoting localization. Although Deputy Director Zhang Guobao hesitated, he finally signed it on the spot. To put it bluntly, it is still risky, otherwise the project can be decided between enterprises.

People in petrochemical companies told Su Yongqiang that the value of one-time feeding of a million-ton ethylene plant is 160 million yuan. If there is something wrong with the "three machines" of ethylene, all the plants have to stop and all the raw materials of 160 million yuan have to be released. How many compressors do you have to buy? By May, 2007, all parties signed the contract, and Shengu Group began to undertake the research and development tasks of cracking gas compressor, propylene compressor and ethylene compressor of the million tons/year ethylene plant.

Break through the core technology again

In fact, Shen Gu has been preparing for the development of million-ton ethylene "three machines" for a long time, and has invested tens of millions of yuan in research and development expenses before getting the contract. Compressor is a customized large-scale complex product system. Without the application of specific engineering, it is of little significance to make an independent prototype. Therefore, Shen Gu’s product development is basically combined with engineering projects, that is, it is put into product development when there is an order. However, the research and development of related technologies for new products has actually started.

An important prerequisite for realizing large-scale equipment is the breakthrough of core technology. For the compressor with heavy drum, the first key technology is impeller. The large-scale compressor brings many practical problems: the reliability of large-size impeller operation, the quality problems caused by welding deformation, defects and thermal stress, and the corrosion of defective parts under bad working conditions.

In 2005, the R&D team headed by Cui Lianshun (female) began to develop the integral milling impeller that only GE mastered at that time. Integral milling impeller has attracted much attention because it is much better than welded impeller in material utilization rate, machining efficiency, machining quality and corrosion resistance, but the process of integral milling is very difficult. First of all, to process the general outline of the impeller on an extremely expensive low-temperature steel, even rough machining requires extremely fine requirements. The position of the first knife is particularly critical, and the whole blank may be scrapped if it is not careful. The tool used is a harder material than the billet, and the redundant part is removed one minute at a time during rotation. Then, this rough machined part is sent to the CNC milling machine for the most critical overall milling, and the straight cutter will mill spiral blades on this whole billet. This is an extremely complicated procedure, and the slightest error will make the whole project go to waste.

Integral milling impeller fixed on milling machine.

After two years’ efforts, Cui Lianshun’s team successfully developed a three-dimensional closed impeller with integral milling in May 2007, making Shengu one of the only two enterprises in the world to master this technology at that time. The maximum diameter of the impeller with integral milling is 1500mm(1.5 m), which has reached the advanced level in the world.

After 2007, Shengu continuously broke through the million-ton ethylene compressor, long-distance pipeline compressor and large air separation compressor because of the application of large-scale integral milling impeller technology. With this technology research and development as the foundation, Shengu has always maintained an outstanding record of "if you do it, you will succeed" in those large projects that adopt the first set of equipment.

The Battle of "Million Tons of Ethylene"

The foundation stone was laid in June 2006 for the million-ton ethylene project of Tianjin Petrochemical Company, and it was officially put into commercial operation in May 2010. The first million-ton cracked gas compressor developed by Shengu for this project was installed in June 2009. When this unit is appraised at the factory, the appraisal meeting will end in 20 minutes. Usually, this meeting will last at least two hours. Then why did it only last for 20 minutes? Because all the data displayed in the instrument are advanced, there is no question to ask after reading the report, and it will be passed directly.

Finally, the relevant leaders made a summary, saying that all indicators showed that this unit was an excellent one. He talked about an experience: after dealing with Shen Gu for so many years, our greatest experience is the enterprise characteristics of Shen Gu: as long as it is a difficult bone, a complex, risky and technically complex project, Shen Gu will certainly win it.

There is another episode. When this million-ton ethylene cracking gas compressor was tested in Shengu, Sinopec invited an expert from Mitsubishi Heavy Industries of Japan to verify it. This is because the only enterprise that can produce this kind of large centrifugal compressor in China is Shen Gu, so no experts other than Shen Gu can do third-party certification. Su Yongqiang was at the scene. Japanese experts carefully watched the whole experimental process of Shen Gu without saying a word, and looked at the data. After all the tests were finished, the leader of Sinopec asked the Japanese expert about his skills, but he still didn’t say anything, just raised his thumb-a world-class level.

Shengu is the cracking gas compressor unit provided by Sinopec Tianjin Petrochemical Company for the million-ton ethylene project.

Sinopec Zhenhai Refining and Chemical Company’s 1 million tons/year ethylene project started in November 2006 and was completed and put into operation in April 2010. Shengu developed the first million-ton propylene compressor unit in China. Both propylene compressor and ethylene compressor are refrigeration, and their working environment is low temperature (propylene is generally used for refrigeration users at -50~0℃).

Zhenhai Refining & Chemical Company, as a user, requires that all partitions of Shengu compressor should be designed and manufactured with low-temperature resistant plates or forgings. In order to reduce the impeller diameter of the unit as a whole, Shengu adopted a high-efficiency three-dimensional impeller with large flow coefficient, high energy head and high Mach number, which was newly developed by R&D department and verified by performance experiments. Since then, Shengu propylene compressor unit has continuously passed the six levels of product design, large-scale casing assembly welding, impeller milling, rotor high-speed balance, mechanical operation test and performance test, and passed the factory acceptance of Sinopec Acceptance Committee in May 2009.

The acceptance experts agreed that the performance index of the propylene compressor unit in the million-ton ethylene plant reached the requirement of the technical agreement that the power deviation of the whole unit should not be greater than 2% of the design power, and the overall technical level reached the international advanced level, breaking the situation that this kind of products depended on imports for a long time.

The ethylene compressor is the last breakthrough in the development of ethylene "three machines" in Shengu. Ethylene compressors are generally used for users of cryogenic separation (-102~-60℃), and Shen Gu didn’t wait until 2006 to develop ethylene compressors for the first time. At that time, Huajin Group in Panjin handed over the order of ethylene compressors for the 450,000-ton/year ethylene expansion project to Shen Gu.

The leading designer of this project is Jiang Yan, a female engineer born in 1973. Without this kind of compressor development experience and external technical knowledge sources, Jiang Yan team worked hard and put in 3 years’ efforts to produce the products. However, this unit, which was put into trial operation in the factory, encountered the problem of excessive vibration as soon as the production line of Huajin was turned on. The reason is that the operating condition of the factory is normal temperature, but it is ultra-low temperature when it is turned on. Jiang Yan and the team searched for technical defects one by one, and finally broke the core problem of rotor structure operating at ultra-low temperature, and realized the stable operation of the first domestic ethylene compressor on January 8, 2010.

The 800,000-ton/a ethylene plant of Fushun Petrochemical Company started construction in April 2009, and the design task of developing the first million-ton ethylene compressor in China by Shengu was also given to Jiang Yan. In this project, Jiang Yan once again showed the courage and creativity of the Shen Gu technical team who dared to go their own way.

The structure and manufacturing process of large-scale ethylene compressor are very different from those of conventional compressors, and the biggest technical problem is the gas charging structure. In order to improve the efficiency of the general compressor, when it is compressed to a certain temperature by several stages of impellers, the compressed medium must be cooled and then compressed. Jiang Yan thinks that if the million-ton ethylene compressor is designed according to this method, it is necessary to add multiple air ducts, which will inevitably divide one compressor into two, resulting in double cost and reduced efficiency.

During that time, Jiang Yan couldn’t eat or sleep, and his mind was full of gas flow field maps. By chance, a sample of a low-temperature rotor detonated her idea: isn’t ethylene at MINUS 100 degrees Celsius itself a refrigeration medium? There is no need to toss the gas inside and out at such a low temperature. After asking for instructions, she decided to adopt the method of filling gas in the cylinder in the million-ton ethylene compressor. However, it is a major change in the structure of the whole unit from adding gas into the cylinder to adding gas into the cylinder. How to optimize the gas flow field without external gas addition, make the two gas additions not interfere with each other, improve efficiency and reduce the difficulty of casing processing, etc., involves the whole production process such as design, technology, processing and manufacturing. And all these problems, Jiang Yan must be solved one by one in the design process of product production source.

Jiang Yan has been cornered many times, and it often took days and nights to design the structure, but it was rejected because of a small defect. However, she and her team didn’t give up. When a structure was rejected, they carefully studied what they could learn from and applied it to the next scheme. In this way, with little accumulation and little improvement, Jiang Yan team perfected the structural design scheme of the unit in constant self-denial. At the same time, they have done a lot of basic research, from rotor dynamics to fluid mechanics to model-level development, constantly calculating every detail of simulating gas flow. After repeated argumentation and simulation, they finally formed a perfect design scheme for filling gas in the compressor cylinder. Practice has proved that the in-cylinder aerated structure greatly improves the performance and efficiency of the product, which is better than foreign units in some aspects [3].

The ethylene compressor should not only meet the strength requirements of the machine, but also improve the efficiency. By optimizing the design of the rotating parts such as the impeller, the Jiang Yan team successively overcame the difficulties such as the rotor structure, and finally formed a perfect design scheme for the million-ton ethylene compressor.

On the evening of February 22nd, 2011, the first million-ton ethylene compressor set in China was successfully tested in the assembly workshop of Shengu Group. In October 2012, Fushun Petrochemical’s 800,000-ton ethylene production plant was completed and put into operation. Since then, Shengu Group has successively signed several large-scale ethylene projects such as Wuhan, Yanshan, Huanggang and Zhenhai, and Jiang Yan team has designed and manufactured 16 ethylene compressor units in three years.

With the continuous success in developing the first set of equipment, Shen Gu is more and more trusted by users. In August, 2011, Sinopec Group and its affiliated Wuhan Branch packaged the products at one time, and delivered the orders for 8 centrifugal compressor sets, 5 reciprocating compressor sets and 4 pumps for the 800,000-ton/a ethylene project in Wuhan to Shengu. The total contract amount exceeded 300 million yuan, including the complete design and manufacture of all ethylene "three machines".

In 2013, Sinopec Wuhan 800,000-ton ethylene project was completed and put into operation. For the first time, Shengu became the general contractor of the million-ton ethylene "three machines". This is a great success, which proves that Shengu has become the mainstream supplier of ethylene "three machines".

In July 2013, the second phase of CNOOC Huizhou Refining and Chemical Company started construction, which is a project to build 10 million tons/year oil refining and 1 million tons/year ethylene on the basis of the first phase of 12 million tons/year oil refining, and it is also the first refinery in the world to centrally process heavy crude oil with high acid content. Its 1.2 million tons/year ethylene production facility was the largest in China and the most advanced in the world at that time [4]. In September 2014, CNOOC signed a contract with Shengu to provide all ethylene "three machines" for Huizhou Refinery Phase II project. In April 2018, CNOOC Huizhou Refinery’s 1.2 million tons/year ethylene plant produced qualified propylene and ethylene products.

So far, Shengu has become one of the top compressor manufacturers in the world.

Zhongsha (Tianjin) Petrochemical Co., Ltd. (formerly Sinopec Tianjin Petrochemical Co., Ltd.) decided to expand its capacity after 10 years of operation of its million-ton ethylene plant. In July, 2020, the nitrogen test run of the cracking gas compressor unit of the largest domestic ethylene plant with a capacity of 1.3 million tons/year, which was installed by Shengu Group, was successful once, and the mechanical performance parameters of the unit reached the high-quality level. The successful commissioning of the unit modification indicates that Shengu Group has been in the leading position in the world in the research, modification and installation of the million-ton ethylene compressor unit.

"Localization" is an important reason why China has made great progress in ethylene production: during the 30 years from 1975 to 2005, China’s annual ethylene production reached 6 million tons, and in the 15 years since the breakthrough of domestic equipment, China’s annual ethylene production reached about 21.6 million tons, and China became the second largest ethylene producer in the world after the United States.

The Battle of "Long-distance Pipeline"

After the compressor of large-scale ethylene plant, another "localization" campaign of Shengu is the long-distance natural gas pipeline compressor, which should start from the "West-East Gas Transmission Project".

In February 2000, the first meeting in the State Council approved the start of the "West-to-East Gas Transmission Project", which is a great project in China’s energy field and the largest national project after the Three Gorges. Up to now, the "West-East Gas Transmission Project" has been divided into three stages, namely, West Line 1, West Line 2 and West Line 3. The general situation is as follows.

The West First Line Project was officially started in July 2002, passing through major provincial administrative regions such as Xinjiang-Gansu-Ningxia-Shaanxi-Shanxi-Henan-Anhui-Jiangsu-Shanghai, and was completed in 2004.

The West Second Line Project started in 2009, passing through major provincial administrative regions such as Xinjiang-Gansu-Ningxia-Shaanxi-Henan-Hubei-Jiangxi-Guangdong, and was completed and put into operation by the end of 2012. The West Second Line is the longest pipeline in China so far, with the highest pipeline steel grade, the largest pipe diameter, the largest gas transmission capacity and the greatest energy saving and emission reduction effect. The trunk line and branch line are all over 8,700 kilometers long, and the natural gas transported has entered the Yangtze River Delta and Pearl River Delta regions along the southeast coast through 15 provinces (autonomous regions and municipalities). If we add the foreign Central Asian natural gas pipeline, it can be said to be an "underground Great Wall of Wan Li Pipeline".

The West Third Line Project started in October 2012. The trunk and branch lines pass through 10 provinces and autonomous regions in Xinjiang-Gansu-Ningxia-Shaanxi-Henan-Hubei-Hunan-Jiangxi-Fujian-Guangdong. The total length of trunk lines and branch lines is 7,378 kilometers, which was completed in August 2014.

However, at the beginning of the "West-to-East Gas Transmission Project", it was also a major project relying on imported equipment. The pipeline of "west-to-east gas transmission" needs a lot of equipment, and the compressor is one of the key equipment, and it is the most important key equipment. The flow of natural gas in the pipeline depends on the power provided by the compressor, so it is necessary to build a pressurizing station every 200 kilometers and pressurize it with the compressor. The key equipment, including compressors, of the West First Line Project are all imported, and almost all of the West Second Line Project are imported. However, the only foreign enterprises that can provide pipeline gas compressors are GE, Rolls-Royce and Siemens.

Sui Yongbin, the chief engineer and consultant of China Machinery Industry Federation, was once the deputy director of the Ministry of Machinery Industry, and he was a man of lofty ideals who campaigned for the localization of major technical equipment for decades. According to his explanation: "The localization of China gas pipeline should not start from now. In the 1970s, the idea of "Sichuan gas flowing out of Sichuan" was put forward. In order to cooperate with "Sichuan gas flowing out of Sichuan", Chinese equipment manufacturers began to develop pipeline ball valves and compressors, and developed gas starters to drive pipeline compressors. For various reasons, the project was finally terminated. "

China decided to launch the "West-to-East Gas Transmission Project", which once again brought opportunities to China equipment enterprises. In Sui Yongbin’s words, "domestic equipment manufacturers have been waiting for opportunities since the beginning of the construction of the first line of the West-to-East Gas Transmission Project, hoping that the key equipment of the long-distance natural gas pipeline in China can use domestic equipment" [5].

However, this wait is nine years.

Shen Gu has been tracking since 1999, when the country was brewing the "West-to-East Gas Transmission Project". Since the first demonstration meeting of localization, Su Yongqiang has participated in 14 of the 16 demonstration meetings, and made speeches at the meeting every time, arguing with arguments, but failed to win a project.

The argument of west-to-east gas transmission is soul-stirring. Sometimes, people from Shen Gu didn’t get a chance to speak at the meeting, so the meeting decided to import it, and we will mention it domestically next time. Before this, Shen Gu did not make a gas pipeline compressor, but this kind of machinery is not complicated from principle to manufacture, and there is no insurmountable technical obstacle for Shen Gu. The problem is not technology-if domestic equipment is used, once problems occur, 500 million people will have no food. Who will bear the risk? Once the compressor is started, it will keep running for 365 days a year, and once an accident occurs, it will affect the overall situation.

[Note: The compressor unit used to be overhauled after 8000 hours of operation, but it was extended to one and a half years, then three years, and now it is overhauled every five years. 】

Even with heavy resistance, Shen Gu has been preparing for entering the long-distance pipeline market. In 2006, Shengu won the contract for the first "cooperative production" compressor, which was designed by GE and manufactured by Shengu. In 2007, I got a prototype, all designed and assembled by Shen Gu, but the prime mover (motor) and frequency converter were bought from abroad, and finally three finished products were made. Although Shen Gu failed to win an order for his compressor, when the country held a commendation meeting for the West-East Gas Pipeline Project, it still commended Shen Gu as an advanced unit and gave Su Yongqiang an outstanding individual. The award was signed by the the State Council West-East Gas Pipeline Leading Group.

Su Yongqiang asked the leaders of the National Development and Reform Commission, who presided over the meeting, how could we be awarded advanced without providing a single unit? The leader’s answer is: users said that although they didn’t give Shen Gu an order, Shen Gu’s intervention allowed them to beat foreigners with Shen Gu and saved them old money, so Shen Gu made great contributions to the country. Su Yongqiang said, "If you want to say so, I deserve it."

The substantial progress of "localization" of the "West-to-East Gas Transmission Project" occurred at the beginning of the construction of the West Second Line.

In April, 2009, the National Energy Administration held a meeting on "Localization of Key Equipment of Natural Gas Long-distance Pipeline" in Shenyang, and decided to carry out the localization research and development of "20MW electric drive compressor set", "30MW gas drive compressor set" and "high-pressure large-diameter welded ball valve" for the West Second Line Project.

Under the organization and coordination of the National Energy Administration, PetroChina took the lead in name, and Shengu developed a 20MW electric drive compressor unit, CSIC 703 developed a 30MW electric drive compressor unit, Shanghai Electric Group and Harbin Electric Group made motors, Anshan Rongxin Electric Power and SVA made frequency conversion, and five companies formed a company. In July 2010, the high-pressure large-caliber welded ball valve was successfully developed in Chengdu; In November, 2011, 20MW electric drive compressor set was successfully developed in Shengu. So far, the key technologies and equipment that restrict the long-distance natural gas pipeline in China have been successfully developed.

PetroChina paid experts from GE to certify the prototype of Shengu, and the result was excellent. Someone at the scene deliberately "provoked" and asked the experts of GE: What do you think of the comparison with the GE unit? The foreign expert replied that everything was fine, and even he was happy when he said it-in fact, he knew that the index of Shengu unit was better than GE.

However, although the policy of "localization" has been decided at the government level, and even domestic equipment has begun to be developed, there are still many obstacles to adopting domestic equipment at the implementation level. During the two years from 2009 to 2011, the debate on whether to adopt domestic equipment in the West Second Line Project has been in a state of "tug-of-war": it was approved at this meeting and overturned next time; After another meeting, it was decided to make it in China, and it was overthrown next time …

After several round trips, Sui Yongbin proposed to plan a cartoon, and Su Yongqiang found a professor from Shenyang Luxun Academy of Fine Arts to draw it. The professor drew several editions and passed them on to Sui Yongbin. Sui said that the painting was wrong and did not reach the artistic conception. Su Yongqiang discussed with Professor Lumei again, explaining to him that this is like tug-of-war, which is related to whether you win or I win.

In the final version, a tug-of-war competition was designed. On one side, there were three foreigners, Siemens, Rollo and GE, and on the other side, there were a bunch of Chinese cheerleaders, with Sui Yongbin and Su Yongqiang at the head. Su Yongqiang said, "I’m the little fat guy on the side, and I look quite like him." The referee in the middle was PetroChina, to see who won, so he finally sided with Chinese. Sui Yongbin is satisfied with this cartoon. At the last demonstration meeting, Sui Yongbin couldn’t speak at that time, so he went up to tell the cartoon himself. Then each enterprise spoke, and as a result, opinions were still inconsistent during the break.

At the end of the meeting, the senior vice president of PetroChina came forward. Before making his final statement, he called Su Yongqiang and Sui Yongbin and said: You all know the responsibility of this matter, and you also know the reason why they don’t agree to adopt domestic equipment. It is that the risk is too great, not only economic risk, but also political risk. If something goes wrong, this job will be lost. He asked Su Yongqiang directly: Do you have confidence? Su Yongqiang said yes. Later, when the meeting resumed, the vice president spoke passionately about the fact that central enterprises must take responsibility, bear national responsibility and support the localization of equipment, which was quite exciting. Finally, the parties decided to sign.

In 2012, the first pipeline compressor independently developed by Shengu was installed as a backup machine in Gaoling pressurization station of the West Second Line. But no one expected that a dramatic scene would happen later: the foreign compressor as the main engine could not be started after maintenance, so it had to start the standby drum sinking unit urgently, and the drum sinking unit was successfully started at one time. This accident made the standby machine of Shen Gu instantly become the host machine.

Since then, the National Energy Administration has organized a national appraisal in Gaoling, and the pipeline compressor of Shengu has received three evaluations: first, the performance has all met the design requirements, and compared with foreign units, it is truly world-class; Second, the fastest driving speed, a successful driving, and foreign units can not do, it will take a long time to drive; Thirdly, the most surprising thing is that the noise of Shengu unit is much lower than that of foreign units. When Su Yongqiang went to the scene, the people who used the unit told him that the Shen Gu unit was so good that after the foreign unit was driven, the people at the scene could not hear each other, but they could hear each other when the Shen Gu unit was running. Shen Gu people never thought that their compressor had this advantage. Su Yongqiang said, in fact, as soon as the mechanical and pneumatic indicators are reached, the noise will naturally come down, so the low noise just shows that the technical performance of the Shen-Gu compressor is excellent.

Shengu’s long-distance pipeline compressor was a hit at Gaoling pressurization station in the later period of the second line project of "West-to-East Gas Transmission" and was highly appraised. At present, there are a few imported compressors driven by gas turbine, and all the electric-driven compressors have been made in China (the number of electric-driven compressors exceeds that of gas-driven compressors). In other words, the compressors used in the first line of the "West-to-East Gas Transmission Project" are 100% imported, and almost all the compressors used in the second line are imported. Up to then, about 300 compressors have been imported into the "West-to-East Gas Transmission Project", and a rough calculation has cost about 30 billion yuan, of which the tax revenue, profits, employment and experience accumulated do not belong to China.

Since 2009, Shengu has independently developed the electric-driven compressor for long-distance pipelines, made a prototype in 2011 and installed it on the spot in 2012 (since then, CSIC 703 has successfully developed a gas-driven pipeline compressor). Since the Shengu compressor was launched at Gaoling Station of the West Second Line, there is no imported pipeline compressor driven by electricity, and the West Third Line has been localized.

On June 26, 2017, three sets of PCL compressor units provided by Shengu Group for Sinopec’s "Sichuan-East Gas Transmission Project" gold station completed 72-hour commissioning test on site, and all indicators were normal and met the design requirements.

On December 28th, 2021, the annual gas transmission capacity of the West-to-East Gas Pipeline System, a landmark project of China’s western development, exceeded 100 billion cubic meters that day. The important reason for this achievement is that in 2018, the country implemented the natural gas pipeline interconnection and supply guarantee project, and Shengu Group provided 14 sets of compressors for this project, which were all put into production in January 2019. In December, 2020, the East Line Project of Sino-Russian Natural Gas Pipeline (Changling-Yongqing) was successfully put into operation, and Shengu provided the design, manufacture and on-site service of 15 compressor sets in 5 stations for this project.

Battle of "100,000 air separation"

When the country implemented the policy of adjusting the energy structure around 2010, the intensive processing of China’s rich coal resources (such as coal to oil, coal to natural gas, coal to olefins, coal to aromatics, etc.) required larger-scale air separation compressors. At that time, in the world, only two German companies, Siemens and Man Turbine, could produce the 100,000-class air separation compressor units needed by large-scale coal chemical plants, and China could only rely on imports.

However, for the competent authorities, the prospect of developing coal chemical industry entirely by imported equipment is "horrible": a set of 4 million tons/year coal indirect liquefaction oil-making device needs to produce 1.2 million Nm?3 oxygen; /Hr air separation island and 12 sets of air compressors with 100,000 air separation (oxygen production). By 2015, more than 70 sets of air separation compressors of this scale will be needed for coal chemical projects approved and to be approved by the state.

In October, 2011, the National Energy Administration organized a working conference on the localization of key equipment of Shenhua Ningmei’s 4 million tons/year coal indirect liquefaction project, and proposed that localization must be carried out. In 2013, of the 12 sets of 100,000 air separation units required for this project, 6 sets were acquired by Hangzhou Oxygen Machine Group (hereinafter referred to as "Hangzhou Oxygen"). After expert argumentation, the National Energy Administration decided to set aside one of the 12 compressor units originally planned to be imported for the air separation unit in Shenhua Ningmei Project as a pilot for localization, and requested Shengu to carry out the research and development of 100,000 air separation compressor units.

This is another challenging task: the design and production cycle of the compressor is one and a half years, and the on-site installation takes half a year, which adds up to a two-year cycle; If it is not successful at one time, the redevelopment will lose four years, and the whole project with an investment of tens of billions of yuan will have to wait. Therefore, Shen Gu must be successful once, which is the most difficult part of "localization".

Shenhua Ningmei planned to import 100,000 air separation compressors at that time, each of which needed 150 million yuan. After the news of Shen Gu’s "localization" came out, the compressor price of foreign enterprises immediately dropped to about 100 million yuan.

The cause and effect of this project once again shows the logic of the "localization" model: major projects to be built in China must use major technical equipment that has not been developed and manufactured in China, but it is at least financially infeasible to rely entirely on imported equipment. Therefore, the government put forward the "localization" policy for the purpose of reducing the cost of using advanced technical equipment and gave China enterprises market opportunities.

However, this time there is a fundamental difference-because Shen Gu is not the same. The key to understanding the road of Shengu lies in this: after entering the 21st century, every time Shengu completed the task of "localization", it did not copy the imported foreign compressor technology, but replaced the foreign compressor with a self-developed compressor.

In fact, Shen Gu has been preparing for this opportunity for many years. Shengu Group has been committed to the development of compressors for large-scale air separation units since 2002, and successfully delivered the first set of 40,000 air separation compressors in China to users in 2004. In the same year, under the condition of no contract, Shengu completed the manufacture and test of a prototype of 35,000 gear-assembled air compressor units by self-financing. In 2006, Shengu developed the first set of 52,000 air separation compressor units in China, which was successfully started after being delivered to users. In 2010, the Energy Bureau of the National Development and Reform Commission determined that Shengu Group was the only R&D center for large turbocompressors in China. In the same year, Shengu completed the research and development design of 50,000 multi-shaft and multi-stage gear assembled air separation booster unit by self-financing, and completed the manufacturing and testing work in 2012, which solved the technical problems of high-efficiency impeller model stage, rotor stability, core component materials and strength analysis, and completed the test verification of more than 20 independent research and development new technologies.

After accepting the task, Shen Gu designated the "Development Project of Compressor Unit Supporting 100,000-class Air Separation Equipment" as "Pioneer Project of Communist party member". Su Yongqiang, the chairman of the board of directors, is personally in charge, Dai Jishuang, the deputy general manager, is responsible for the implementation, and the chief designer of the project is Wang Chuanghua, the vice president of the battle-hardened design institute.

As it is another "first set" project, the technical team of Shengu has no experience to learn from, whether it is the structural design of compressors and superchargers, seals and shells. However, they rely on mature large-scale centrifugal compressor technology and large-scale axial compressor technology, and adopt the structural design of "axial+centrifugal" air compressor and multi-shaft and multi-stage gear assembled supercharger in the R&D and design process. They have successively overcome a series of technical problems, such as high-efficiency impeller design with large hub ratio mixed flow and small hub ratio and high Mach number, cooperative coupling of various complex flows, dynamic analysis of rotor with special structure, complex connection structure of rotor and stator, complete set design of unit equipment, control and adjustment of complex working conditions and so on.

In order to hand in the best technical solutions to users, they constantly communicate with Hangyang Group and users to ensure the accuracy of each parameter, and also cooperate with foreign enterprises in individual technical fields to ensure the advanced nature of various technologies.

In August 2013, Shengu won the trust and recognition of experts and users with its technical scheme and service concept, and signed a commercial contract with Hangzhou Oxygen Group (air separation unit) and Hangzhou Steam Turbine Group (supporting steam turbine) for Shenhua Ningmei super-large air separation unit.

The manufacturing process is also a challenge. In the rotor workshop, the compressor spindle, which weighs nearly 30 tons, needs to be combined horizontally in three stages, and it needs to be successful once. There is only a gap of 0.02-0.04mm between the left and right sections of the spindle and the middle section, which is equivalent to one tenth of the hair. A slight negligence in installation will give up all previous efforts. On average, the 44 bolts on the left and right sides of the spindle have to be hammered more than 800 times and stretched more than 1000 times by workers. The rotor length of the air compressor in the 100,000 air separation project is 76.6 meters, which requires more than 300 people to repeatedly scrutinize the safety of the tooling, equipment and site. Each impeller has a weight of one ton, so the operator should wear a safety belt and stand on the assembly frame more than 7 meters high to operate.

In the stator workshop, the processing technology of the central casing is complex, and the same process involves the coordinated operation of multiple teams. According to the product structure characteristics and process flow, the workshop worked out a special production plan for the central casing of the 100,000 air separation project, and decomposed the plan into each process, strictly controlled the planned time nodes, kept track of the production progress at all times, and rationally arranged personnel, and each link was taken care of by a special person, so as to ensure the seamless docking of all teams and groups and ensure the production and processing were foolproof.

In the structural workshop, Nie Wanlong, who has provided technical services for the group’s heavy and difficult products for many times, was selected as the technical "chief surgeon" from the pre-production technical preparation. After receiving the drawings of 100,000 air separation units, Nie Wanlong immediately carefully analyzed the rationality of each process link and possible problems, and communicated with the design, process and other departments to solve the problems one by one. Subsequently, this heavy baton in Nie Wanlong’s hand was passed to the "Shenyang Welding King"-the technician Zhen Bide. Zhen Bide never let go of any problem, keeping a close eye on the production of 100,000 air separation units, and working overtime every day has become a common practice.

Rotor of 100,000 air separation compressor.

The development of large-scale equipment, especially the first set of equipment, requires large-scale test means. The power of large-scale air compressor set for 100,000 air separation plant exceeds 60,000 kilowatts, so it is very difficult to design and manufacture. In order to ensure that the development of the unit is foolproof, the product must be tested at full speed, full pressure and full load before leaving the factory. In 2012, Shengu invested 700 million yuan to build a world-leading 100,000 kW test bench in Yingkou, which was approved by the National Energy Administration as the national "Construction Project of R&D (Experiment) Center for Large Turbine Compressor Units". According to the actual operating parameters of users, the test-bed can test all the equipment including compressor, turbine, auxiliary machine, control system and so on.

From July 23rd to August 3rd, 2015, the 100,000 air separation compressor unit independently developed by the R&D teams of Shengu Group, Hangzhou Steam Turbine Group and Hangzhou Oxygen Group has successfully carried out the performance tests of mechanical performance and aerodynamic performance at full speed and full pressure for three times, and all the performance indexes meet the requirements of the contract and reach the international advanced level. Soon after, on August 23rd, 100,000 Nm?3 with a length of 35 meters, a height of 15 meters and a weight of 478 tons; /h The air separation compressor unit was commissioned at Shengu Yingkou Experimental Base, and conquered more than 200 guests including leaders, experts and customers with excellent performance.

On May 15th, 2017, the first domestic air compressor set of 100,000-class air separation plant independently developed by Shengu Group was successfully commissioned, and the linkage test of No.12 air separation unit of Shenhua Ningmei coal indirect liquefaction demonstration project was successfully completed. The operation data showed that all mechanical properties and aerodynamic performance indexes of the unit reached the international advanced level. On July 11, 2017, this compressor unit was connected to the grid and produced qualified oxygen and nitrogen products. The oxygen and nitrogen quality indicators met the design requirements and the mechanical properties of the unit were stable. The user Shenhua Ningmei specially sent a happy news to pay tribute to all the staff of Shengu Project Department and awarded the honorary title of excellent supplier of Shengu Turbine Company’s coal-to-liquid project.

On August 25, 2017, China Machinery Industry Federation and China General Machinery Industry Association jointly hosted a demonstration project of 4 million tons/year coal indirect liquefaction in Shenhua Ningmei-an industrial operation review meeting of domestic 100,000 air separation units and air compressors. The final evaluation opinion proves that the domestic 100,000-unit air separation plant and air compressor are another breakthrough of major equipment in China, and their main technical performance has reached the advanced level of similar foreign plants and products, which can meet the needs of large-scale domestic coal chemical, petrochemical and metallurgical projects for 100,000-level and above air separation plants. It is recommended to popularize them as soon as possible.

The 100,000 air separation compressor unit is a major breakthrough of Shengu in recent years. From the process, the whole process of "localization" is relatively smooth due to the direct intervention of the state authorities. This also shows that the market of major projects is deeply influenced by the government, and the role of the government in promoting "localization" at the "system" level is irreplaceable.

Following the breakthrough of Shenhua Ningmei Project, Shengu received contracts from two other enterprises in succession. In April 2020, Shengu Group designed and manufactured two sets of 105,000 air separation compressor units for Ningxia Baofeng Energy Group, and produced qualified oxygen and nitrogen products. This is another major breakthrough in the development of large-scale air separation units in China after the successful start-up of 100,000 air separation units developed for Shenhua Ningmei in May 2017.

On the basis of accumulating several sets of design and manufacturing experience of compressor units in large-scale air separation units, Shen Gu has successively developed 60,000, 80,000, 100,000, 120,000 and 150,000 Nm?3; Independent research and development of large air separation units with /h class, with 60,000 to 150,000 Nm?3; The design and manufacturing capacity of serial centrifugal compressor sets for /h air separation units shows the prospect of a full range of domestic compressor sets for large-scale air separation units replacing imports in the field of large-scale coal chemical industry.

The technical and product breakthroughs of Shen Gu in the last 20 years can’t come together, so we can only describe the general situation. Importantly, Shengu’s products have covered the upstream, midstream and downstream of petrochemical industry, and have rushed to the forefront of the world in almost all fields, which is a great contribution made by Shengu to China’s industry. In addition to the aforementioned fields of ethylene and natural gas long-distance pipelines and coal chemical industry, the technical breakthrough of Shengu also includes the following fields: compressors for oil production and oil refining, compressors for natural gas liquefaction (LNG) refrigerants, compressors for fertilizer production devices, and compressors for chemical fiber production devices. In addition, Shengu also provides high-end pumps, such as nuclear power plant main pump and oil pipeline pump.

It can be said that Shengu has fully covered the large-scale compressor units needed by petrochemical industry, national defense and military industry, and its market share is roughly as follows: centrifugal compressor is 85%; Large blowers account for 40%; The reciprocating compressor in petrochemical industry is about 80%; High-end pumps range from 50% to 85% according to the variety.

It is precisely because Shengu quickly realized the large-scale compressor, the improvement of technical level and the enhancement of supporting capacity that it met the development of petrochemical industry in China in the past 20 years. The president-level leader of a big user personally said to Su Yongqiang: "Mr. Su, Shen Gu has made great contributions to the development of China petrochemical industry. Your contribution to the country should be measured not by how much profit Shen Gu has produced, but by the social contribution you have made to the country. With Shen Gu, we dare to say no in front of foreigners. "

Revealing the fastest supercomputer in the world： it takes 32 years for the earth to turn on the phone for one minute.

　　Xinhua News Agency, Nanjing, June 20th: One minute on the phone counts as 32 years — — Revealing the World’s Fastest Supercomputer "Shenwei Light of Taihu Lake"

　　Xinhua News Agency reporters Jiang Fang and Cai Yugao

　　On June 20th, the International Supercomputing Conference (ISC) in Frankfurt, Germany announced the new TOP500 list of global supercomputers. The "Shenwei Taihu Light" developed by the National Center for Parallel Computer Engineering and Technology won the first place with nearly three times the operation speed. What’s more exciting is that the system has realized the localization of all core components including the processor.

　　How fast is the computing speed of the new overlord of supercomputers? What does full localization mean? Has China Supercomputing reached the top of the world? Xinhua News Agency reporter walked into the Wuxi Center of National Supercomputing, which is responsible for the operation and maintenance of the system, and unveiled the mystery of "Shenwei Taihu Light" for you.

　　What’s the feeling of the fastest computing in the world? One minute of operation is equivalent to 32 years on earth.

　　The peak performance of the system is 125.436PFlops, ranking first in the world;

　　The continuous performance is 93.015PFlops, ranking first in the world;

　　The performance-to-power ratio is 6051 mflops/w, which is still the first in the world.

　　The news from the International Supercomputing Conference is confusing just by looking at the data.

　　"Simply put, the one-minute computing power of this system is equivalent to 7.2 billion people around the world using calculators to calculate continuously for 32 years; If mainstream laptops or personal desktops produced in 2016 are used as a reference, ‘ Light of Taihu Lake ’ It is equivalent to more than 2 million ordinary computers. " Yang Guangwen, director of Wuxi National Supercomputing Center, introduced.

　　Walking into the National Supercomputing Wuxi Center, in a room of 1,000 square meters, the reporter saw the "real body" of "Shenwei Taihu Light":

　　It consists of 40 computing cabinets and 8 network cabinets. Each computing cabinet is slightly larger than a household two-door refrigerator. When the cabinet door is opened, four super nodes consisting of 32 computing plug-ins are distributed in it. Each plug-in consists of four operation node boards, and one operation node board contains two "Shenwei 26010" high-performance processors. One cabinet has 1024 processors, and the whole "Shenwei Taihu Light" has 40,960 processors.

　　"Each processor is equivalent to the computing power of more than 20 commonly used laptops, and more than 40,000 pieces are assembled together, and the speed can be imagined." Yang Guangwen said.

　　Global supercomputing, only fast and unbreakable. The significance of working on supercomputing research is not only "speed war", but more importantly, winning "application war".

　　Fu Haohuan, deputy director of the National Supercomputing Wuxi Center, introduced that relying on the "Shenwei Light of Taihu Lake", the research team with the theme of Tsinghua University realized the numerical simulation of the global 10-kilometer high-resolution earth system for the first time, which will comprehensively improve China’s ability to cope with extreme climate and natural disasters; The numerical simulation results of the return path of "Tiangong-1" by the National Computational Fluid Dynamics Laboratory are exciting and will provide accurate predictions for the smooth return of "Tiangong-1". The drug screening and disease mechanism research carried out by Shanghai Institute of Drugs completed the routine calculation in just two weeks, which greatly accelerated the progress of drug design in leukemia, cancer and avian influenza … …

　　From "glass room" to "restricted sale" of 25 square centimeters, completely breaking the 30-year technical blockade.

　　Thirty years ago, supercomputer users in China had a mysterious "glass room": Americans sold a supercomputer to China, wrapped it in opaque glass, and technicians from China were not allowed to enter without authorization.

　　Professor Wang Lanning from the Institute of Global Change and Earth System Science of Beijing Normal University still remembers this "technology enclave" in China. "Only a few authorized scientists in the country can enter the glass room, and it is under the supervision of Americans. Once the program runs, the machine is locked back to the glass room immediately. The so-called supercomputing speed seems to be a high-performance computer at best today, but it was an unattainable peak for China at that time. "

　　In the 1980s, China has gradually entered the ranks of countries that independently design and manufacture supercomputers, but the shortcomings of key components and technologies such as core processors can only be controlled by others, which directly leads to the fact that although China is a "big buyer" of foreign supercomputers, it cannot have the matching "bargaining power".

　　Stepping into the "Twelfth Five-Year Plan", with the key support of the National 863 Project, China’s supercomputing development has continuously made breakthroughs. "Tianhe II" won "six consecutive championships", while the list of top 500 supercomputers in the world is getting longer and longer, which has aroused the vigilance of the United States. In April, 2015, the US government announced that four China organizations related to supercomputers were included in the restricted export list, with the purpose of locking up the rapid development of supercomputers in China through restricted sales.

　　It is the incentive brought by this blockade that has enabled China to make great efforts to develop fully localized "Shenwei" series supercomputers until it reached the top of the international list.

　　As a result, the thin block "Shenwei 26010", which is only 5 cm square, has not only become the heart of "Shenwei Taihu Light", but also become a sharp weapon for China’s independent research and development to break the 30-year technical blockade. Between the square inches of 25 square centimeters, 260 computing cores and billions of transistors are integrated, reaching more than 3 trillion calculations per second. The computing power of a single chip is equivalent to three supercomputers ranked first in the world in 2000.

　　Yang Guangwen said that there has always been a controversy about whether we should independently develop the core processor. Some people say that if we haven’t done it for so many years, we should simply stop doing it and "adopt" one. There are also voices that the high-speed rail model of introduction, absorption and re-innovation is very good. Why do we have to close the door and engage in independent ecology? "If we don’t adhere to the completely independent ecology, we can’t do it for more than ten years, and then we can’t do it for more than ten years. It is impossible to have the great power of core indicators going hand in hand today." Liang Jun, deputy director of the National Parallel Computer Engineering Technology Research Center, said.

　　From the "six consecutive championships" to the first billion China supercomputing, there is still a gap from the top of the world

　　Supercomputers, known as "the sharp weapon of the country", are the embodiment of the comprehensive strength of the country’s science and technology. From high-end materials, to life sciences and biotechnology, to deep-sea exploration and space technology, it is inseparable from the support of supercomputing. As soon as the good news came out, some people thought that China Supercomputer had "firmly" stood at the top of the world from now on. Is that really the case?

　　Yang Guangwen said that it is undeniable that the success of "Shenwei Light of Taihu Lake" indicates that China’s supercomputer research and development capability has already reached the world’s leading level, but there is still a clear gap between China and developed countries in terms of technical reserves and system stability.

　　The battle for speed is the most direct confrontation in the field of supercomputing. Compared with the glory of "Tianhe No.2" and "six consecutive championships", it is extremely difficult for Shenwei Taihu Light to occupy the first place in the world for a long time. In July last year, the United States launched the "National Strategic Computing Plan" with the goal of building the fastest computer in the world by 2025.

　　"In the next five to ten years, from one billion times per second to one billion times per second is the decisive place for supercomputer development." Relevant researchers from the National Center for Parallel Computing said that although supercomputing countries are deploying, there are many key technical links that need to be solved. Taking energy consumption as an example, the annual electricity consumption of Shenwei Taihu Light reaches 15 MW, which is equivalent to the electricity consumption of three Tsinghua University. Even if billions of times can be achieved with the existing technology, the energy consumption will be very amazing.

　　More importantly, no matter how fast the speed is, the development of supercomputing is always for "application", and this is still the shortcoming of the current development of supercomputing in China.

　　Zhang Jian, a researcher at the Computer Network Information Center of the Chinese Academy of Sciences, said that China’s ability to solve problems with supercomputing systems has been insufficient for a long time, and related commercial application software is still monopolized by foreign countries, and it needs to be further improved in software development, application development and personnel training. Only by transforming the advantage of "making good" into the advantage of "making good use" can we truly promote industrial innovation and upgrading.

QQ Flying Hand Tour： The Last Explosion in the Crack of the ＂Eat Chicken＂ War

Tiger sniffing note: 2017 is about to pass, and the competition in the game market has also ushered in the final battle. At the end of the year, "QQ Flying Hand Tour" became another explosion. Although "changing hands" is an old routine, the reputation and data of this game have performed well, and the DAU has exceeded 10 million in 24 hours. Tencent also took this opportunity to complete another category layout.

This article is transferred from WeChat official account’s "Gamelook(ID:GameLook_News)", the original title."2017 mobile game final battle: the racing category won the full score, and the results of < QQ speeding mobile game > were eye-catching".

2017 is about to pass, and in the mobile game market, the competition for user time by category is becoming more and more fierce. Whether the MOBA category continues to triumph, the MMO market is "unmoved", and even new categories such as tactical competition, leisure racing and strategic warfare are springing up like mushrooms after rain. The taste of users in the mobile game market has been more and more "sharp". When manufacturers finally realized that the importance of market competition between categories was higher than the confrontation between similar competing products, Ma Xiaoyi, senior vice president of Tencent, pointed out more directly: the winner takes all, and the outcome between categories ultimately depends on the contest of head products.

It’s the end of the year. Standing on the tail of 2017, looking ahead, the mobile game market in China experienced the initial boom in 2014 and the rise of IP products in 2015. Until 2016, MOBA and MMO each accounted for half of the country, and the glory of the king rode the dust. However, what kind of description and game should be used to describe the coming 2017?

QQ Speeding Tour is a good option. The biggest trend in the mobile game market in 2017 is undoubtedly verticalization. Whether tactical competition is for FPS or racing is for leisure, users’ needs have become more and more subdivided and more and more difficult to meet. As the head product of racing category, "QQ Speeding Hand Tour" was launched on the third day from the end of 2017. Then, it handed over the answer sheet that others could not complete in a year:

As of December 30th, the official announcement of "QQ Speeding Mobile Games" shows that the number of daily active people has exceeded 10 million. Correspondingly, "QQ Speeding Mobile Games" broke 10 million in 24 hours, ranking first in the iOS free list and second in the best-selling list. We have made a preliminary observation, and the content discussion of "QQ Speeding Tour" on social media platforms such as WeChat, Weibo and QQ Space has been overwhelming in the past few days.

Chess is said to be an official, ending, testing mental strength, chess power and the layout of grass snake gray line. Near the end of the year, when all eyes were on the chicken-eating war stirred up by Netease and Tencent, they quietly won the 45 million-reserved "QQ Flying Mobile Games", which thundered in silence and really won the final battle of the 2017 mobile game.

Of course, it is not the only one. The jump of WeChat games, love and the success of producers in local categories are all new dark horses that cannot be ignored at the end of 2017. However, on the influence of IP, on the volume of products, on the longer-term user ecology and even industrial ecology, "QQ Speeding Mobile Games" must be an unavoidable industrial topic for many colleagues next year.

The number of daily active users has exceeded 10 million, and "QQ Flying Tour" only took 3 days.

DAU (number of daily active users) is an important indicator to measure the status of mobile games in the industry. In the mobile game industry, DAU can be called a masterpiece (such as Fantasy Journey to the West), and it is already a myth in the industry that DAU can break through 10 million, such as the glory of the king, such as Yin and Yang Division, and it is not too much to say a national game. Today, the "Ten Million DAU Club" has welcomed the fastest membership, and QQ Speeding Tour is full of energy to catch up with its predecessors: it took Yin and Yang teachers two months, the glory of the king three months, and QQ Speeding Tour only three days to achieve the same goal.

All this did not happen overnight. Before that, the three-month 45-million-yuan booking result of "QQ Speeding Mobile Games" has made the industry sit up and take notice. After it was launched on December 27th, it accumulated the enthusiasm of players for half a year and fully released it. For example, the dragon was shocked: 10 million yuan was added in 24 hours, reaching the new goal that other head products took months to complete. The results of reaching the top of the free list within 8 hours and the second place in the 24-hour airborne bestseller list have been maintained until now. The performance of "QQ Flying Hand Tour" may make people rethink, and racing may really be an underestimated category.

Of course, we will also doubt whether this will be limited to the operation of one wave, just like many new tours. However, as far as word of mouth is concerned, there is no trace of an abrupt end: the score of "QQ Speeding Mobile Games" is as high as 8.5 in TAPTAP, which is much higher than several popular mobile games on the market at present. No matter from the old players of QQ Speeder, game media or early adopters, we have seen a lot of similar compliments.

What is it that created such unreasonable data and word of mouth of QQ Speeding Tour?

The Change and Invariance of "QQ Flying Hand Tour"

The product itself is always the best explanation. When we experience "QQ Speeding Hand Tour", we can easily feel that, as an end-game adaptation product, "QQ Speeding Hand Tour" has changed and remained unchanged in product design.

The so-called "unchangeable" refers to the insistence of QQ Speeding Mobile Games on racing games in essence: the most essential demand of users for racing games, that is, the exciting pleasure brought by racing. The original group of people who traveled in those years insisted on "the restoration of IP experience" from the beginning, not just the so-called "IP restoration". This attribute determines that the mobile game is not only restored on the classic right-angle curve track, familiar with racing models, music, etc., but also allows classic operations such as small spray, air spray, landing spray and CWW spray, without any discount on the experience due to the limitations of the mobile phone. Do you feel familiar with this transplant ability? "the glory of the king" once brought MOBA into thousands of households, and all this was completed by Tianmeiqi’s R&D team, which was famous as early as the end tour era.

The so-called "changed" is to adapt to the choices made by mobile phones. Give up the complicated operation mode that is difficult to implement on a large scale, and replace it with a simpler and easier drift operation. Just press and hold two keys to easily complete the drift, which is convenient for novice players to master quickly. To this end, a large number of novice tutorials are introduced in the game, and the frustration of users is reduced through incentives, so that players are willing to take the initiative to master skills and stimulate their desire to learn. At the same time, while retaining the most classic racing game, QQ Speeding Tour has also made timely adjustments to the props game: breaking away from the speed confrontation of lonely heroism, creatively introducing concepts such as props transfer and team opening into the racing category, so that the competition of skills can deepen the strategic and tacit confrontation between people and teams.

Innovation and restoration are always two ends of the balance, and "QQ Flying Tour" has added the same weight to both ends. It is familiar with old players and friendly to new players. As a result, it broke the record of 10 million DAU in three days.

Everyone knows the truth, but few people did it before QQ Flying Tour.

On the other hand, the attempt of "QQ Speeding Hand Tour" at the marketing level has not made this golden signboard dusty. For example, it is the first time for many users to see the H5 interaction that was jointly launched with Q and completed by QQ. Compared with the WeChat game, this H5, which simulates the operation of QQ flying hand tour, is polished more fastly in terms of image quality, operation and creativity, and is more in line with the tastes of young people. Some people joked that this H5 has solved the eternal problems of "try before buying" and "experience before downloading" in mobile games.

Pan-entertainment cooperation, Jason’s cooperation, can be regarded as the emotional choice of old players. Before that, in the player survey released by QQ Speeder, Jason ranked in the top number of votes. Jason’s theme song "FAST", after its launch, quickly hit the charts. And "QQ Flying Tour" has never stopped blasting the feelings of the old players since the appointment, and there is a team that loves QQ flying. It took 2,280 hours to create a page-turning animation, which attracted a climax. It is hard to imagine that a 2-minute animated video actually contains 3,000 frames, 5,000 hand-painted manuscripts, 4 months to polish and 100 eggs that evoke tears of players.

For "QQ Speeding Hand Tour", everything comes at the right moment, whether it is product or marketing. Facing the 470 million registered users accumulated by QQ Speeder and the vast market of Tencent Mobile Games with more than 600 million monthly active users, the achievement of 10 million DAU in three days of QQ Speeder Mobile Games is the first dazzling note in this broad background.

Leading the winners and losers among categories, can "QQ Flying Hand Tour" do it?

Unprecedented, this is to describe the height that "QQ Flying Hand Tour" has reached. It’s too cold at the top. Where will the next milestone of "QQ Flying Tour" be?

We need to think about this problem from the perspective of game categories. As mentioned above, 2017 is a showdown between sub-categories, and the head products in the categories are an important carrier to carry the category showdown.

For example, Ma Xiaoyi, senior vice president of Tencent, said that each category has a definer, a breakthrough and a follower. Only products with high quality can promote category breakthrough. In the field of racing mobile games, the real definer has not been born before, and the racing category is still a blue ocean. At present, the achievements of "QQ Speeding Tour" can already help the racing category to complete the definition.

Next, what it has to do is to change this category from a "niche game" recognized by the public to a "national game" in a new field.

In the end, which vertical category will give birth to a new national game has not yet been determined. Most of the views held by the industry are optimistic about tactical competition, while a few are free from emerging categories such as racing, strategy and sandbox.

The author believes that it is difficult for tactical competition to give birth to a real national game. Not to mention the pain of changing the operation of the FPS game terminal to the hand strap, from the point of view of several testers in this category, they are all playing pass the parcel’s games. From millet gunfight to wilderness action. The confrontation between Glorious Mission and Terminator 2, in the final analysis, is robbing the same group of users-those who are interested in "eating chicken" are still circulating among different products, and there is no formula, and the giants have not seen the embryonic form. The genuine Jedi survival mobile game created by Tencent and PUBG is expected to arrive late in 2018, and the dust of this category has settled, still waiting for time to give an answer.

There is no dominant head product, which gives other categories enough time window to cultivate and snatch users and fulfill the desire of category breakthrough. And at the right time, "QQ Flying Tour", neither too early nor too late, just stepped in this gap.

The greater the user’s demand, the lighter the way to meet the user’s demand, and the higher the possibility of acquiring users. The characteristics of racing category are two or three minutes, which determines that it is more suitable for users’ fragmentation time. The core tone of competition gives users the reason to invest time repeatedly.

The following story is not difficult to guess, through the experience and cultivation in the field of e-sports, as well as the demand occupation of more subdivided users. "QQ Flying Hand Tour" will continue to enter the users, firmly pulling around, snowballing to complete the breakthrough of the whole category.

In the end, the winner takes all.

The mobile game market never refuses a new peak. It is the emergence of new giants and new national games that keeps the whole market alive. Judging from the score at the end of 2017, the racing category has won out of 100, but in 2018, how can other categories catch up? It will take time to give us an answer.

Chopsticks Brothers’ new work ＂We Are the Sun＂ shows different brotherhood.

Following the divine comedy "Little Apple" which swept across the north and south of the river, the Chopsticks Brothers recently launched a new single "We Are the Sun" at the end of the year and the beginning of the year, sending blessings and hopes for the new year with the help of singing. This inspirational theme single with exciting lyrics and catchy melody is expected to follow old boys, Father and Little Apple.

Since their debut in 2007, Chopsticks Brothers have experienced many ups and downs on the road of musical dreams. No matter how difficult the situation is, they encourage each other and never give up. Just as Shawn, a chopsticks brother, once said in Weibo, "No matter how much pain you experience, a good friend will always be with you." Men say thank you directly and never affectedly, and all their words of thanks are integrated into this song and sung to each other. This is also the reason why this theme song is launched for a game with team interaction as the core gameplay, just for those two words: "brother". This time, it is different from the sad route of old boys and Father and the retro feelings of Little Apple. The Chopsticks Brothers chose the theme of inspiration and dreams as their creative theme, and Wang Terry personally wrote lyrics. The lively and powerful electronic rock style is full of excitement and writes inspirational positive energy in life, just as the lyrics sang, "We are the sun, without anyone’s light, life is a battlefield everywhere, and anyone can." "We are the Sun" has also officially become the theme song of the flight group of "National Aircraft War", and the "Chopsticks Brothers" made a special trip to shoot a theme poster for this purpose, leading the whole people to fight for the "dream" together. The singing of "Chopsticks Brothers" is full of the burning of youth and the full bloom of life, which brings a new hope and encouragement when the new year comes. Such a lively and exciting "We Are the Sun" with catchy melody, with the full interpretation of the creator of the Divine Comedy "Chopsticks Brothers", is also expected to capture the square dance again and set off a new wave of Divine Comedy.

On the road of dreams, they have also experienced silent cultivation and persistence, and experienced ups and downs and doubts. However, no matter what difficulties they experienced, "Chopsticks Brothers" always retained their initial intention to fight for their dreams, and responded to disputes with music and works. These experiences are also the emotional core of their creation "We Are the Sun". It is only because of empathy that the songs have more touching power. Today’s "Chopsticks Brothers" not only focus on the music field, but also successfully cross the border in the fields of director and performance. At present, the movie "Love Saint" starring Shawn partner NI YAN is about to be released, perhaps just like what is sung in this song, "Chopsticks Brothers" also carries their own dreams, constantly tries and challenges themselves, and brings new surprises again and again in more capacities such as director, actor and singer, so that the outside world can see a more multifaceted one.

Fifty years of Bloodline Awakening, the 11th generation of Civic Hatchback is about to start Bloodline Spraying Mode

In 1972, in response to the oil crisis, Soichiro personally oversaw Honda’s first family car, the CIVIC, which, with its practical and fuel-efficient skills, quickly took over the market in Japan and made its way out of Asia and into North America.

However, Honda engineers and Honda Soichiro, who were born with sports and fighting spirit, did not want CIVIC to stop at home. So, in that era, crazy engineers, through the optimization of the engine and suspension, built CIVIC into a driver’s car. Therefore, from the first generation to today’s 11th generation Civic, they not only represent Honda’s understanding of the economy of the car, but also represent Honda’s passion.

If every generation of Civic’s sedan is a clever combination of sports and practicality, then the Civic’s HATCHBACK hatchback model is the best carrier of sports high energy. In the more than ten years since the Civic entered the country, we can also see the Civic’s sportsmanship and evolving ability. In the upcoming Dongfeng Honda 11th generation Civic HATCHBACK, Honda’s sportsmanship is once again witnessed.

After half a century, the Civic hatchback pays tribute to the classics like this

Friends familiar with the development history of the Civic should know that the early generation of the Civic was actually a standard hatchback. At that time, the Civic brought driving fun beyond the sedan with its shorter body and sportier control settings. After many rounds of evolution and iteration, in order to better meet the needs of the times, the sedan Civic came into being and gradually became the mainstream. But despite this, the early hatchback version of the Civic has still become a spiritual totem in the hearts of car fans. In other words, the hatchback version of the Civic is the essence and inheritance of the entire Civic family.

Focusing on the present, the return of the 11th generation Civic HATCHBACK undoubtedly inherits the glory of the Civic family for half a century. In terms of design, it can also be seen that it pays tribute to the classics. In the front part of the car, the difference between the 11th generation Civic HATCHBACK and the current sedan version is not obvious, ensuring the consistency of the Civic family. But in terms of details, the designer has thought carefully about the 11th generation Civic HATCHBACK. For example, in the China Network, the sedan version of the Civic uses a black horizontal bar decoration, while the 11th generation Civic HATCHBACK uses a more sporty honeycomb design, which not only looks more sporty, but also further enhances the recognition of the 11th generation Civic HATCHBACK.

Of course, the side is the finishing touch of the 11th generation Civic HATCHBACK. The hatchback structure that fans like to see makes it inherently have a high return rate. With the current popular blackened through taillights, bilateral double exhaust layout, and large-size sports-style wheels, it greatly increases the refinement of the whole car while enhancing the sports atmosphere. The reason why it is no longer so radical may be that the existence of the Type R makes the 11th generation Civic HATCHBACK closer to the exquisite trend image of the hatchback Civic itself.

Of course, refinement and trend should not be reflected only in the appearance design. So the 11th generation Civic HATCHBACK also keeps pace with the times in terms of interior design, adopting the latest interior design concept of the Honda family. The new style of three steering wheels, through the cellular style air conditioner trend, floating central control large screen, large-size LCD instrument and other elements have greatly enhanced the interior of the 11th generation Civic HATCHBACK with a sense of advanced and technological sense.

If you are careful enough, you will find that the designer also specially used red stitching decoration on the entire interior of the 11th generation Civic HATCHBACK to highlight its uniqueness. Under the collision of red and black colors, the sports genes of the 11th generation Civic HATCHBACK are undoubtedly revealed. At the same time, the blessing of technology and sports will undoubtedly further gain the favor of contemporary young people.

The true Civic spirit is constantly evolving and adapting to the times

As the saying goes: "It is easy to fight the country, but difficult to defend the country". As a classic model that has swept the world, how does the Civic always lead? We can find the answer from the past Civic.

The first-generation Civic, with its easy-to-drive and fuel-efficient characteristics, became the first choice for people’s economy in the context of the "oil crisis" of the year. For example, the third-generation Civic in 1983 created the MM concept to further meet people’s practical needs for family cars. To the eighth-generation Civic, the layered digital instrument panel exceeded all people’s imagination of the technology cockpit at that time. From this, we can draw the essence of the Civic’s evolution lies in its continuous innovation based on the needs of the times.

Nowadays, with the development of the times, the change of technology, and the change of consumer demand, the current car has become more comprehensive. Especially in terms of intelligence, it has become an important indicator that today’s consumers cannot ignore. And Honda designers who have always been good at innovation have naturally sensed the change of consumer demand, and have injected Honda’s latest intelligent configuration and technology into today’s 11th generation Civic HATCHBACK.

For example, today’s people use the car-machine interconnection system with high frequency, and today’s 11th generation Civic HATCHBACK will also be equipped with Honda CONNECT 3.0 intelligent guidance interconnection system. Not only does the car-machine UI have a delicate picture and smooth operation, but the built-in functions have long been rid of the monotony and conservatism in people’s impression of Japanese cars. Real-time road navigation, convenient voice control system, and rich network connectivity functions further bring users a convenient and advanced car experience. At the same time, this system also supports OTA, so that young and fashionable you will always be at the forefront of the times.

In terms of driving assistance, Honda’s best Honda SENSING safety sensor system is also equipped with the 11th generation Civic HATCHBACK. It includes lane keeping assistance system, lane departure warning system, adaptive cruise, traffic congestion assistance, active braking and other functions, allowing you to pursue speed and passion while being foolproof, while also meeting the needs of this era for intelligent driving systems.

The sporting spirit of the Civic is also constantly evolving

The early Civic used a 1.2L gasoline engine with 60 horsepower to meet household needs. In order to better fit the style of driving enthusiasts, the Civic continuously enhanced the engine performance in the later stage. With the appearance of 1.5L engine, VTEC engine, and Earthdream engine, the sports performance of the Civic was also continuously enhanced. Now, the 11th generation of Civic HATCHBACK has also inherited the sports spirit of previous generations of Civic, and has completed a new round of optimization and upgrading for the core power system and chassis system of vehicles.

In terms of power, the 11th generation Civic HATCHBACK offers two sets of powertrain options. The first is the 1.5T engine of the 240TURBO model matched with the CVT gearbox. It has to be said that this is a nearly perfect solution. This high-power 1.5T engine can reach a maximum power of 134 kilowatts and a maximum torque of 240 Nm. This power system is enough to meet the power needs of many fuel enthusiasts. At the same time, the combination of the CVT gearbox can also achieve the best fuel-saving performance at medium and low speeds while ensuring efficient driving.

Of course, if you are an extreme control enthusiast, don’t regret it. Because Dongfeng Honda also introduced the MT manual transmission model of the 11th generation Civic HATCHBACK for you. Under the current wave of new energy, even Volkswagen has announced the cancellation of the manual transmission, but Dongfeng Honda still insists on guarding your driving control obsession, which is really rare for car fans.

It is reported that in addition to the 240TURBO version, the 11th generation Civic HATCHBACK will also provide an e: HEV version equipped with the fourth generation i-MMD. Its built-in 2.0L Atkinson cycle engine with dual motors will bring more powerful performance, but at the same time it can achieve better fuel consumption than the fuel version. This is also the latest achievement of the e: HEV strong electric and intelligent hybrid released by Honda in August. All in all, no matter what kind of power, the 11th generation Civic HATCHBACK is performance-first, to meet the needs of driving enthusiasts first.

This can be seen not only from the power configuration, but also from the chassis structure of the 11th-generation Civic HATCHBACK. Honda engineers’ determination to control progress is even more evident. On the basis of inheriting the advantages of the previous-generation Civic chassis, engineers have also made further upgrades to the chassis, such as widening the rear wheel base to improve the stability of the body when cornering, and also upgrading the bushing material, re-tuning the electronic steering system, and using the front suspension adapter ball head with a lower friction coefficient. All these methods, although more effort and cost are expended, have only one purpose: to further improve the handling performance of the chassis. From a variety of powertrains to the ever-strengthening chassis performance, it is enough to demonstrate the above sentence: Civic’s sporting spirit is also constantly evolving, and the 11th generation Civic HATCHBACK is undoubtedly the best embodiment.

ConclusionThe 11th generation Civic HATCHBACK is not just a brand new hatchback from Dongfeng Honda, it is a model that inherits the sportsmanship of Honda for half a century. Of course, it inherits the sportsmanship of Honda, but also the spirit of continuous innovation. The comprehensive progress from design to texture, from intelligence to performance has also made this upcoming new car have stronger competitive strength, and it has once again demonstrated the sportsmanship of Honda’s blood while perfecting the Civic family matrix.
