New energy engine and Core Technology
Although car manufacturers are different in promoting their new energy engine technology, but in fact the new engine's technical categories, as well as energy development always has its own rules to follow. In this way, a lot of technology has achieved some results.
Three-dimensional framework for classification
CPPCC Standing Committee, Tsinghua University Automotive Safety and Energy Director of State Key Laboratory of High Ouyang Ming Pao reporter to the Chinese industry, new energy vehicles in the fuel, can be divided into liquid fuel, gas and electricity are three.
"Using these three categories at this stage of the product is motor fuel diesel vehicles, compressed natural gas vehicles and electric vehicles. After, the use of these three categories of fuel future product will be hybrids, hydrogen fuel cars and the use of nuclear power completely without pollution of pure electric cars. "he said.
Engine technology, there are three types, namely, internal combustion engines, bio-and gas engines and electric.
Ouyang Ming Gao said: "The development of internal combustion engines is steam from an advanced progressive development of the hybrid diesel, hybrid and also mixed after weak, moderate and severe mixed mixing process to the final development of rechargeable hybrid; gas fuel Engine technology is the next most viable hydrogen fuel power. "
Some results have been obtained abroad
Japan has just released a new energy direction is the core of a car engine battery, hydrogen fuel cells and clean diesel Third, the United States tend to study in electric cars.
But both the hydrogen-powered or electric, the world's major car companies of all kinds of new energy technologies are the core of some progress has been made, and research for new energy vehicles are still continuing basis.
Japan's hybrid cars can be a weak energy 38%, and in order to meet the needs of the development of new energy vehicles, Japan has begun the road, transforming the surrounding facilities, including residential facilities. Nissan has also been made in battery substantive results.
In Germany, there are already relying on wind power and hydrogen energy technology to produce this completely green manufacturing method of hydrogen has been studied for the BMW hydrogen-powered vehicles have a positive effect.
Related Toyota official told reporters, although Toyota has introduced a hybrid car powered products, but Toyota has not given up any one kind of new energy vehicles 研究.
Domestic lack of core technology
Domestic automobile enterprises of new energy technologies are not advanced. China Machinery Industry Federation, Zhang Xiaoyu, vice president told reporters that China's auto enterprises corresponding technology is still not able to produce that kind of like the Toyota Lexus hybrid vehicles.
Ouyang Ming Gao also said: "At present China is the core technology of new energy vehicles also lack of competitiveness." He believes that China's new energy vehicles in the core technology platforms, there is no surprise. Example, the engine electronic control, direct injection, electric assist supercharger, electric valve, the compression ratio and other technical aspects of the variable.
"At present, the weak Honda hybrid car can saving 38%, while China's products can only reach 20% of the energy. This proves the domestic new energy vehicles in the electric control technology is needed to be research."
But the domestic auto manufacturers are working hard. Brilliance Automotive relevant official told reporters, Brilliance Automotive, mainly in hybrid currently conducting a study, but did not give up other Technology. "We believe hydrogen is the future direction of alternative energy sources, but to achieve hydrogen will take some time." She said.
Great Wall Motors at this year's Beijing auto show to display the electric car, but the reporter learned from the Great Wall Motor, the car to mass production, may also need a couple years. "Because the current for battery recycling and other issues yet to be resolved." Great Wall of relevant official told reporters.
Europe and the United States on preferential policies
Not only in technology, and foreign automakers in China there is a gap. In the preferential policies, China has not substantive policy, while other countries have a lot of support for new energy vehicle development policymaking.
In the U.S., hybrid vehicles each light a concession of up to 3400 U.S. dollars, of the natural gas and other alternative fuels for cars costs some 50% to 80% of the financial subsidies; Japan's electric, natural gas and other clean energy vehicles, 50% tax cuts, and give the same level with the traditional car spread of 1 / 2 concessions subsidies, while natural gas fuel supply device can enjoy some of the equipment cost of subsidies; France to give each an electric car 15,000 francs in subsidies, of which 10,000 francs to automobile factory, 5,000 francs (including taxes) to purchase electric vehicles for private or corporate enterprises; in the UK, if driving hybrid vehicles entering the London urban area, will waive the cost of £ 5 into the city.
These preferential policies for the development of new energy vehicles are a powerful impetus.
