Although auto manufacturers are currently propagating their own different new energy engine technologies, in fact, the technical classification and development direction of new energy engines have their own rules. On this road, many technologies have achieved certain results.
Three-dimensional frame classification
Ouyang Minggao, a member of the Standing Committee of the National Committee of the Chinese People's Political Consultative Conference and director of the State Key Laboratory of Automotive Safety and Energy at Tsinghua University, told the China Industry News reporter that new energy vehicles can be classified into liquid fuels, gas fuels, and electricity.
“The products that use these three types of fuel at this stage are gasoline, diesel, compressed natural gas, and electric vehicles. After the development, the future products that use these three types of fuels will be hybrid vehicles, hydrogen fuel vehicles, and nuclear power. Contaminated pure electric vehicles." He said.
In engine technology, there are also three types, namely, internal combustion engines, biological and gas fuel engines, and pure electric.
Ouyang Minggao said: "The development direction of the internal combustion engine is to gradually develop from advanced gasoline engine to hybrid power, and the hybrid power will go through a process of weak mixing, moderate mixing and heavy mixing and eventually develop into rechargeable hybrid power; The most feasible technology for the engine's future is hydrogen fuel power."
Some achievements have been made abroad
Japan has just released the core direction of new energy vehicle engines in terms of batteries, hydrogen fuel cells, and clean diesel. The United States tends to study electric vehicles.
However, whether it is hydrogen power or electric power, major auto companies in the world have made some progress in researching various core technologies of new energy, and research on new energy vehicles is still continuing.
At present, Japan's weak hybrid vehicles can save energy by 38%, and in order to adapt to the development of new energy vehicles in the future, Japan has already started the reconstruction of roads and surrounding facilities, including residential residential facilities. Nissan has also achieved substantial results in terms of batteries.
In Germany, there are currently technologies that rely on wind energy to generate electricity and produce hydrogen. This completely green method of hydrogen production has positive effects on hydrogen-powered cars that BMW has been researching.
Toyota’s relevant person in charge told reporters that although Toyota has introduced hybrid products, Toyota Motor has not given up any research on new energy vehicles.
Lack of core technology in China
The new energy technologies of domestic auto companies are not advanced. Zhang Xiaozheng, vice president of the China Federation of Machinery Industry, told the China Industry News that Chinese auto companies currently do not have the corresponding technology to produce hybrid cars like Toyota Lexus.
Ouyang Minggao also said: "At present, China still lacks competitiveness in the core technologies of new energy vehicles." He believes that China has not made any astonishing move in the core technology platform for new energy vehicles. For example, in the engine electronic control, direct injection in the cylinder, electric auxiliary boost, electric valve, variable compression ratio and other technologies.
“At present, the Honda’s weak hybrid vehicles can save energy by 38%, while China’s products can only reach the level of energy savings of 20%. This proves that domestic new energy vehicles still need to be tackled in terms of electronic control and other technologies.â€
However, domestic auto makers are also working hard. The relevant person in charge of Brilliance Automotive told the reporter that Brilliance currently conducts research mainly on hybrid power, but has not abandoned research on other technologies. "We believe that hydrogen power is the future direction of alternative energy, but it will take some time to achieve hydrogen power," she said.
Great Wall Motor showed off the electric car at this year's Beijing Auto Show. However, the reporter learned from Great Wall Motor that the car may take a year or two to achieve mass production. "Because the current problem of battery recycling has not yet been solved." The relevant person in charge of Great Wall Motors told reporters.
European, American and Japanese preferential policies
Not only in the technical field, there is still a gap between China's and foreign auto companies. In terms of preferential policies, China has no substantive policies, while other countries have already introduced many policies to support the development of new energy vehicles.
In the United States, the concession for each light-duty hybrid vehicle can be up to 3,400 U.S. dollars, 50% to 80% for the increase in the cost of natural gas and other alternative fuel vehicles, and 50% for Japan’s clean energy vehicles such as electric and natural gas. Taxes are reduced and a discount of 1/2 of the difference between conventional vehicles of the same class is granted. In addition, the equipment and equipment for natural gas and other fuel supply equipment can receive a partial subsidy; France gives a subsidy of 15,000 francs per electric vehicle, of which 10,000 francs. The automobile factory, 5000 francs (including tax) for the purchase of electric cars for private or company companies; in the United Kingdom, if you drive a hybrid car into the city of London, will be waived 5 pounds into the urban area.
These preferential policies have a strong driving effect on the development of new energy vehicles.
