The internal combustion engine technology will remain the mainstream for a long time to come

The new energy automobile industry has been rapidly growing rapidly. In 2017, the production and sales volume of new energy vehicles once again reached a new high. According to the data from the China Automobile Association, the output of new energy vehicles in 2017 was 794,000, an increase of 53.8% year-on-year; The sales of energy vehicles reached 777,000 units, a year-on-year increase of 53.3%.

As a new growth point of China's auto industry, new energy vehicles carry the important task of boosting China's development towards becoming a powerful automobile country. Under the stimulation of subsidy policies and dual-integration policies, the progress of China's new energy auto industry has been obvious to all, and it has been aroused in the Chinese auto market. The trend of new energy vehicles is spreading to the world.

The picture comes from the network

Under the trend of the times, some domestic and foreign car companies have made the development of new energy vehicles a top priority. BAIC Group “leads the 2025 Strategy”, Chang’an “Shangri-La Plan”, Geely “Blue Geely Action”, GAC New Energy Strategy All of them have clearly defined their respective tasks for the development of new energy vehicles in the coming years. For overseas car companies, the Volkswagen Group plans to fully electrify by 2030. General Motors plans to launch at least 10 electric vehicles in China by 2020. Mercedes-Benz plans to provide hybrid or pure electric versions for all its models by 2022. Toyota also stated that it will mass produce pure electric vehicles by 2020. In addition, with the "fuel sales ban" also appearing on the national policies of some countries, traditional fuel vehicles seem to be facing an unprecedented crisis.

When the discussion on the "fuel sales ban" is getting hotter and hotter, in addition to supporting the rising demand for new energy vehicles, the industry's voice on "internal combustion engines still occupy the mainstream for some time in the future" is not deterred. On January 15th, 2018, the “International Seminar on Transformation and Upgrading of the Power Technology of Conventional Fuel Vehicles”, China’s Minister of Science and Technology pointed out that “the internal combustion engine will remain the main force of the market for a long time and it is difficult to replace. Status, especially in freight, passenger transport, and ship transportation, is playing an important role."

In fact, when the weight of the industry gradually favors the New Energy Vehicle segment, many traditional car companies are also making efforts to transform. At the same time, they still do not give up the development of internal combustion engines. Therefore, the industry generally believe that in the future a longer period of time The internal combustion engine will continue to be the dominant driving force of the automobile. New energy vehicles and fuel vehicles will coexist for a long time.

At the Automotive and Environmental Innovation Forum held by Gasgo Motors last month, Zhan Yisong, Dean of the Chang'an Automobile Research Institute, stated that “As an important plan for the third venture, Chang’an Automobile has released the Shangri-La Plan to complete the three major new energy projects by 2020. Platform R&D Why emphasize special platforms, because a lot of them are doing research and development improvements, and in 2025 they completely stopped selling traditional fuel trucks, and in 2050 there are 70% engines, this is not a contradiction, we are still developing efficient engines, but to In 2025, there must be a relatively large motor. There is a product plan before 2025, including pure electricity and plug-in hybrids. For example, the mileage of plug-in hybrids is expected to exceed 1,000 kilometers.” Prior to this, Zhu Huarong, president of Chang’an Automobile Co., Ltd. had Publicly stated that "in 2025, Chang'an Automobile will begin to completely stop the sale of fuel vehicles of traditional significance and realize electrification of the full-spectrum products." This move by Changan Automobile has caused the controversy of the "forbidden sales of fuel vehicles" to sweep the industry circles once again. And Zhan Yusong's position, it seems to be a clarification of the mistaken Changan Automobile "forbidden sales of fuel vehicles."

Xu Zheng, director of SAIC's passenger car technology center, believes that “we must ensure the sustainable development of the company, at least in the industry consensus - our energy-saving cars and new energy vehicles, and even fuel electronics technology, will still be in comparison Coexisting for a long time, and on a mid-to-long-term scale, by 2030, vehicles with internal combustion engines still dominate the market share."

Analysis of the domestic auto market, new energy vehicles have made great progress in recent years, but in the overall market share, the proportion of new energy vehicles is minimal. According to the data from the China Automobile Association, the domestic sales of new energy vehicles accounted for 1.56% of the total auto market in 2015; this proportion rose to 1.8% in 2016; the new energy auto market accounted for 2.7% in 2017, an increase of 0.9% over the previous year. . For the automotive industry, the development of new energy vehicles is a general trend, but traditional fuel vehicles and new energy vehicles are not your life and death. The co-existence and co-existence of the two is still a common phenomenon for a long time to come.

According to Zhou Jianguang, vice president of Dongfeng Motor's technical center, “The technical upgrade of the powertrain is a permanent theme. The high-efficiency engine is the core technology for achieving low-carbon energy. At our Dongfeng Company, we believe that the technical upgrade of the powertrain is permanent. On the subject, we have a clear-cut view that the upgrading of the traditional powertrain is a topic that must be done for a long time to come and is a very effective way."

Su Wanhua, an academician of the Chinese Academy of Engineering and an expert on internal combustion engine power engineering, expressed the same opinion. He believes that the internal combustion engine will continue to dominate for a long time to come. He pointed out that “the number of vehicles in the country’s internal combustion engines exceeds 300 million, and China’s product share is also in a large range. In recent years, the internal combustion engine is developing at an unprecedented speed, and the international engine's research and development focus is to improve the heat efficiency, and 60% of effective heat efficiency is a short-term predictable goal, and the long-term goal is more optimistic. Now, the technical personnel of internal combustion engine companies are very clear."

While the technology of new energy vehicles is advancing by leaps and bounds, the internal combustion engine technology in China and even in the world is constantly improving. Xin Jun, President of Hansen Technology and the national “Thousand Talents Program” special expert Xin Jun, said: “The independent engine branded by China’s current market is a good engine and The gearbox is basically competing with Europe and the United States on the same platform. It is similar to the one produced by others in 2014 and 2015. The technology content is almost the same in the case of the same price, and the performance is similar. "The current volume production in China has increased the so-called direct injection. Pressure gasoline engine, dual VVT technology configuration, it is 100%, further optimization of the combustion, fuel consumption can be reduced by 3%.In the supercharger above, originally the pneumatic air valve was changed to electronic air valve oil consumption and then reduced by 1%; Variable valve generation, fuel consumption can be reduced by 2%; quenching cylinder technology has been commonly used in the United States, in the 6 cylinder 8-cylinder machine fuel consumption is very significant ... "

The rise of China's auto industry can not be separated from the outstanding contributions of new energy vehicles, but at the same time can not ignore the efforts made by the traditional fuel vehicles, the establishment of China's auto power has to rely on the continued development of both, and common progress. Tan Xuguang, president of the China Internal Combustion Engine Industry Association, pointed out that traditional energy sources are still the main driving force in the world in the near future, but they must be accelerated and upgraded. New energy is an irreversible development trend in the world and it must speed up layout and lead. Therefore, while vigorously developing the new energy automotive industry, the transformation and upgrading of the internal combustion engine technology is the responsibility of every automaker. As for how long it will take for “a long time to come,” some say that at least two decades, others have said that Before 2040, the final answer has yet to be revealed in the progress of the development of new energy vehicles and internal combustion engine vehicles.
