The major project of China's 863 Electric Vehicles pointed out that electric vehicles should include: hybrid vehicles, pure electric vehicles and fuel cell vehicles. The special project also requires that the research and development of electric vehicles should follow three principles. One is to target industrialization, the other is that enterprises are the main body, and the third is the guarantee of institutional innovation. Among them, pure electric vehicles need not only to break through key technologies, but also to achieve initial industrialization. In the next 50 years, due to the superior fuel economy and environmental performance of hybrid vehicles, it will certainly replace the existing internal combustion engine vehicles. In the long run, once oil resources enter the depletion period, they will prompt the price of petroleum fuels to surge and exceed hydrogen fuel. At that time, fuel cell vehicles will be able to achieve true industrialization.
At present, hybrid vehicles that rely on petroleum resources, especially gasoline hybrid vehicles, have made considerable progress in Japan and the United States. Not only industrialization has been achieved, but also the sales volume has increased year after year, making it a bright spot in the history of world automotive technology development.
The way out for gasoline engines is to use hybrid technology
The reason why petrol cars have low fuel efficiency and poor emissions is that the operating conditions of gasoline engines change with the change of car driving speed, and most of the operating time of gasoline engines is at a low load with extremely low efficiency. In addition, ordinary gasoline cars have to sacrifice efficiency and environmental performance in pursuit of maximum power at maximum speed. In order to solve these problems, various new technologies have emerged. Practice has proved that merely improving the internal combustion engine technology to improve the efficiency of gasoline engines and reducing emissions not only fails to catch up with diesel engines, but also does not meet the needs of future cars in this area. So where is the way out of the gasoline engine?
The way out for gasoline engines is to use hybrid technology. Relying on the implementation of gasoline hybrid technology, the performance of gasoline cars caught up with diesel cars. The feature of this technology is that no matter how the vehicle driving conditions change, the operation of the gasoline engine is always working under the stable or nearly stable maximum fuel efficiency. The maximum power, idle speed, acceleration, deceleration, transition and the maximum speed are eliminated. Low load and other conditions have achieved an 80% reduction in fuel consumption of ordinary cars, and the vehicle's deceleration braking energy recovery system can also reduce fuel consumption by 20%.
Concentrate on the Industrialization of Gasoline Hybrid Cars
In order to catch up with the advanced level of cars in the world, the strategy adopted by China in the past was: relying on the introduction of production technology from abroad to improve our country’s “electronic management of automobilesâ€, “internal combustion engine†and “development of new exhaust aftertreatment devicesâ€. techinque level. Practice has proved that relying on this strategy, it is impossible to make the three aspects of technology catch up with the world level.
The above three technologies are all weaknesses for China. Can these three weaknesses be turned into strengths? Gasoline hybrid technology can do this. First of all, it is difficult for China to develop gasoline engines for hybrid vehicles on the basis of gasoline engines. Second, under the mode of operation of hybrid vehicles, the existing high EGR can be slightly improved to meet the world's most stringent ultra-low emission standards. Therefore, there is only one weakness in the "Electronic Management of Vehicles". If the allocation of national science and technology funds is considered by the nation's IT industry and motor industry, concentrate on the development of a universal drive energy electronic coordination control system and the corresponding implementation components such as motors, inverters, etc., namely: Universal energy control system dedicated modules The integration, series of high-efficiency electrical appliances, and the modularization of motor components are quickly sold on the market, and the industrialization of gasoline-powered hybrid cars is more practical.
In summary, we can easily see that as long as the earth still has oil, there will be gasoline, and gasoline hybrid cars will survive. Therefore, gasoline hybrid technology life is at least as long as diesel technology, not a transitional technology. Gasoline hybrid technology is a technology that enables China's cars to quickly catch up with the world's advanced level, and it is a powerful measure to reduce China's dependence on foreign oil and ensure energy security. Therefore, it will certainly become the only way for the development of gasoline engines in China.
