Although some domestic auto companies have also turned their attention to the research and development of hybrid vehicles, at present, the true hybrid vehicle technology is still dominated by foreign automakers, and there are not many domestic hybrid hybrid vehicles. Hybrid car is really just a transitional model? Secretary of the Chinese Internal Combustion Engine Oil and Clean Fuels Branch Secretary-General Professor Shuai Shi gave a different answer — “The hybrid vehicle is not a transitional model. The perfect combination of its internal combustion engine and motor, will Ensuring that hybrid power should be a long-term technical line in the development of automobiles." Not a transition product Similarly, as the type of new energy vehicles that the government pays attention to and promotes, compared to the domestic car companies' enthusiasm for pure electric vehicles, the hybrid models are still considered to be transitional models. "The market has such views, but I do not agree." Shuai Jinshi said, "For a long time in the future, hybrid power should be the mainstream technology route, not only will not easily be eliminated, and is more likely to be the main force for future development. The reason for this is that the energy-saving (about 30%) and emission reduction (about 40%) of hybrid vehicles have obvious effects, which not only solves the problem of over-reliance on oil in traditional automobiles, but also realizes diversification of automotive energy sources and continues to be used for development. Many years of mature internal combustion engine combustion technology, these are the unique advantages of hybrid vehicles. Mature engine work methods and the perfect complement to the motor, can completely make hybrid vehicles have a broader space for development." At present, the theory of oil depletion and crisis is universally accepted by the world. In this regard, Shuai Jinshi believes that although oil may theoretically be exhausted one day, it does not affect the development of the internal combustion engine as one of the main forms of power for hybrid vehicles. On the one hand, it is undeniable that oil will still play a major role in vehicle energy for a long time. On the other hand, the hybrid internal combustion engine is improved, its fuel can be diversified, not limited to oil, it can also be burned. Various fuels such as natural gas, methanol, ethanol, dimethyl ether, biodiesel, and hydrogen, among which ethanol and biodiesel are also renewable energy sources. Shuai Shishi said: "The internal combustion engine device has been continuously groping for more than 100 years. It can be said that the technology is very mature and there is still great potential for energy saving and emission reduction. At present, people have not found a combustion power plant with higher thermal efficiency to replace the internal combustion engine. The device is the technical advantage of the internal combustion engine, which also ensures that the hybrid vehicle has the advantages of a traditional car with high performance and high endurance while maintaining the advantages of a pure electric vehicle." Do not conflict with environmental protection Energy conservation, environmental protection and carbon reduction are the fundamental driving forces for the development of new energy vehicles. The combustion of conventional internal combustion engines will pollute the atmosphere with exhaust gases such as carbon oxides, nitrogen oxides and hydrocarbons, which will have an impact on the ecological environment. This is one of the factors that we do not like about the internal combustion engines of conventional vehicles. In this regard, Shuai Shishi said: "How to reduce the emission of pollutants is indeed a problem for the internal combustion engine power plant. However, as the technology improves and matures, the exhaust gas generated by the hybrid internal combustion engine can be purified through a post-treatment device. The conversion efficiency of harmful substances can reach more than 98%, which not only reduces the emission of harmful pollutants, but also can even play a role in purifying the air. Japanese car manufacturers once conducted a test in Tokyo, and gasoline vehicles adopt ultra-low emission control technology. The exhaust gas from the tailpipe is cleaner than the air being drawn in." At the same time, hybrid motors use electric motors, making hybrid vehicles also have the advantage of low emissions from electric vehicles. At present, the hybrid electric motor can be charged in two ways. One is that the fuel is combusted to be charged by the internal combustion engine, and the other is that the external electric network can be used for charging. The charging method of the internal-combustion engine battery does not solve the problem of sources of energy diversification, or mainly depends on fuel such as gasoline or diesel to be converted into electricity. The PLUG-IN hybrid that is currently under development can be used to generate electricity from gasoline or other fuels, or it can use the grid to charge the battery. As the power sources of the grid are widely used, such as wind power, hydropower, nuclear power and solar power, the vehicle is solved. The diversification of energy sources shows that the hybrid PLUG-IN method has a good application prospect. As we all know, the advantage of pure electric vehicles is zero emissions, but the problem of the endurance of pure electric vehicles urgently needs to be broken. At present, pure electric vehicles are only suitable for use in some foreseeable trips, such as bus lines, tourist attractions, and other fixed locations. The organic combination of the internal combustion engine and the electric motor used in the hybrid vehicle can fully achieve the energy efficient and clean use effect, not only ensuring the maximum degree of energy conservation and emission reduction, but also ensuring the superior dynamic performance of the car itself. The key is to reduce costs Despite the broad prospects for the development of hybrid vehicles, high prices are still a barrier to people accepting new energy vehicles. How to reduce the cost of new energy vehicles. Shuai Shishi put forward three opinions. He said: “First, it should be noted that the domestic hybrid technology has developed relatively quickly in recent years, but there is still a big gap between the core technology and the international, especially the power battery technology has yet to be a breakthrough. With the large-scale production in the future, With technological advancements, the cost of new parts and components such as batteries and motors can be reduced, and the overall hybrid vehicle price can also be reduced.Secondly, the government should see that the energy saving and emission reduction effect of hybrid vehicles is very impressive. Large capital investment will reduce tax exemption for car companies that produce new energy vehicles, and encourage companies to accelerate the mass production process.In the terminal sales market, the state should introduce policies such as subsidy or reduction of purchase tax, encouraging people to accept the use of new energy vehicles. Is the most important selling point, especially in the context of high oil prices, the benefits of energy conservation can activate the hybrid vehicle market." When talking about hybrid cars still emitting greenhouse gases, Shuai Jinshi also said: "This issue cannot be avoided, but it should be evaluated scientifically and comprehensively." He said, "From a local point of view, pure electric vehicles are Zero emissions are very clean, but overall, from the perspective of primary energy, nearly 80% of China’s power generation is still in thermal power, and thermal power will inevitably generate greenhouse gases, so we don’t use pure electric vehicles in China at present. Fundamentally solving the problem of low carbon, this is exactly the direction that the Chinese automobile industry should work together."
