Recently, at the United Nations Climate Change Conference in Paris, the “Zero Emission Vehicle Alliance†formed by Germany, the United Kingdom, the Netherlands, Norway, and parts of the United States announced that by 2050, countries in the Union will not allow the sale of fuel vehicles. It can be seen that the transformation of the auto industry is a general trend. With the support of a number of favorable policies, the future of new energy vehicles will dominate the automotive consumer market.
A few days ago, a news attracted widespread attention from the automotive industry: Germany, the United Kingdom and other zero-emission automotive alliance countries proposed that the production and sale of fuel vehicles be completely banned until 2050, and the future automobile market will be replaced by electric vehicles and hydrogen energy vehicles. .
Previously, Toyota Motor Corporation, known for its production of hybrid models, has also proposed a similar plan to completely stop the production of pure gasoline and diesel vehicles before the arrival of 2050.
It can be said that the zero-emissions coalition is basically in line with Toyota Motor's thinking, that is, through the use of at least hybrid electric mode to solve the long-term emissions and environmental issues, and thus get rid of the long-term dependence on petrochemical energy.
"Mixed" and "do not mix" of the dispute <br> <br> about the future direction of development of new energy vehicles, large electric direction toward the development is already thinking globally consistent. Only during the transition period towards pure electric vehicles or fuel cell vehicles is it right? To develop hybrid vehicles. This is still a difference between China and other major countries.
It can be seen from the definition and catalog of existing new energy vehicles in China that unless it is a plug-in hybrid, other types of products do not cover the corresponding national and local subsidies. Of course, this is inextricably linked with China's current industrial structure and product structure. From the point of view of proper protection of domestic industries and encouragement of independent R&D and production, this approach is not at all acceptable.
In fact, from the perspective of energy conservation and reduction in the use of fossil fuels and reduction of emissions, any form of hybrid fuel or electricity blending can be more energy-efficient than pure fuel vehicles at both ends of integrated energy use and energy recovery. Advantages, this point has been supported by most experts including the head of the National 863 Program's Energy Saving and New Energy Vehicle Major Project Expert Group and Professor Ouyang Ming of Tsinghua University a few years ago.
The China Industry News reporter was also informed in numerous interviews that even in a wide range of areas, including buses and other large vehicles, hybrid power is still a very realistic solution for the medium-to-long term. It is not like some people only have Life within three to five years.
Domestic hybrid lightweight issue is not resolved <br> <br> the current Chinese own brand of a number of related products, the development of hybrid vehicles, most related manufacturing companies did not form a hybrid design in the true sense thinking. At present, the main automotive manufacturers have only developed and produced hybrid fuel conversion products for ordinary fuel vehicles. They have not redesigned the fuel engine in strict accordance with the need for hybrid power, or at least did not attach importance to the engine as a specialized product.
Needless to say, this point can only be seen from the fuel engine displacement and the entire vehicle weight of some domestic hybrid vehicles.
According to data provided by the consultants of the China Automotive Engineering Society and director of the expert committee of the Automotive Lightweight Technology Innovation Alliance, the hybrid chassis produced by the same chassis, the weight of the domestic self-owned brand products is usually higher than 10% of mature foreign products, and some It can even reach 30% or more. If you compare Chinese and foreign cars with the same chassis size, if the weight of the relevant domestic models is 1.2 times that of foreign models, then the relevant driving range, acceleration performance, etc. do not have to compare it - more than people in a circle of fat It is impossible for the car to gain an advantage in the "running" game.
Dedicated engine is more powerful <br> <br> in a recent technical seminar, China Automotive Engineering Research Institute, Dr. Zhang Yaming, deputy general manager of Chongqing Electric Automotive Systems Co. Kerry pointed out that foreign mature products such as hybrid Toyota The third-generation Prius, the Toyota Lexus IS300h/GS300h, the Honda Accord PHEV, and the Honda Fit and Verizon hybrid models are all equipped with a dedicated Atkinson cycle engine.
Compared with the traditional Otto cycle engine, the Atkinson cycle engine has certain advantages. For example, the Atkinson cycle engine has an excellent part-load economy and can achieve higher economical efficiency in conjunction with the electric motor. In the starting and low speed phases of the car, the low-speed torque characteristics of the electric motor precisely compensate for the low-speed torque difference of the Atkinson-cycle engine, and the high thermal efficiency of the Atkinson cycle engine can better meet the characteristics of these environmentally-friendly models. . Therefore, the use of the Atkinson cycle engine in the hybrid vehicle's engine has become one of the hallmarks of the advanced hybrid model.
A comparison table of fuel consumption levels of various hybrid models provided by Dr. Zhang Yaming can also be seen that the specific weight per hundred kilometers of fuel consumption in different hybrid models (liter/ton In the comparison, a hybrid-series-parallel hybrid model had the best result of 2.97 liters/ton; the related fuel consumption results of the four hybrid-power split hybrid models were: 3.03 liters/ton and 3.28 litres respectively. Ton, 3.35 litres/ton and 3.36 litres/ton; the relevant results for the three parallel P2 hybrids are: 3.18 litres/ton, 3.58 litres/ton and 3.76 litres/ton; results for a range-up hybrid model It is 3.71 liters/ton. In contrast, hybrid-series-parallel hybrid fuel economy is the most prominent.
Relying on the continuous advancement of science and technology, the future automobile world will be the era of the decline of traditional fuel vehicles. The end of pure fuel vehicle production in 2050 is not just a dream.
