Professor Chen Quanshi, deputy director of the Automotive Research Institute of Tsinghua University and director of the electric vehicle research office, said in an interview with reporters that with the gradual shortage of oil resources, reversing the current oil-based energy utilization pattern and achieving energy diversification will become the future development of the automotive industry. the trend of. According to statistics, cars consume about 85% of China’s total gasoline production and 20% of total diesel production each year. According to the forecast of the Ministry of Industry of the Development Research Center of the State Council, the fuel demand of motor vehicles is 138 million tons by 2010 and 2020 respectively. 2. Hundred million tons, which is 43% and 57% of the total national oil demand that year, that is to say, at that time, the car will have to “eat†about half of its self-produced and imported oil. China has long ceased to be an oil exporter in the 1990s, and new oil demand will increasingly depend on imports. China's foreign dependence on foreign investment increased from 7.6% in 1995 to 33.8% in 2000. In 2003, China imported 91 million tons of crude oil, an increase of 31% over 2002. By 2020, China's oil consumption is expected to reach about 450 million tons, and the dependence on foreign oil will reach 60% at that time. In the long run, the ultimate solution is not to restrict the development of the auto industry, but to look for alternatives to oil and develop new energy vehicles. In addition to using gasoline as a fuel, many energy-saving and environmental-friendly automobiles have appeared on the market, such as diesel cars, electric vehicles, LPG vehicles, natural gas vehicles, methanol vehicles, ethanol vehicles, DME vehicles, and biodiesel vehicles. According to Professor Chen Quanshi, compared with gasoline engines, diesel engines have features such as high efficiency, low fuel consumption, long life, and reliable use. They have reduced the fuel consumption of gasoline engines by 45% to 60%. However, compared with the number of diesel cars with a ratio of nearly 50% in the European market, the number of diesel cars in China is relatively small. The most important factor constraining the development of diesel cars is the quality of Chinese diesel. At present, the quality of diesel fuel in most regions of China cannot meet the requirements for the use of diesel technology in the latest Euro III and IV emission standards. Although the diversification of automobile energy cannot be achieved overnight, with the reduction of non-renewable energy sources, the increase of environmental pollution, and the maturity of its own technologies, new energy vehicles will eventually become the best choice for people, with broad market prospects. It is fancy this point. According to EU statistics, the market share of diesel cars in the major EU countries has increased rapidly from 16% in 1991 to 44% in 2003. Last year, sales of diesel cars in Germany accounted for 30% of the total sales of cars, while the fastest increase in the number of diesel cars was also counted in France, Belgium and Austria. At present, the major car manufacturers in Europe have recently launched cars that meet the Euro IV emission standard. This indicates that modern diesel technology can completely clean exhaust gas as well as gasoline engines and other alternative fuels. Due to the generally high prices of oil products in European countries, even though the price of diesel cars is on average 1,000 to 1,500 euros more than that of equivalent gasoline cars, Europeans are still willing to buy diesel cars due to fuel economy. The U.S. Department of Energy has also established the “Hydrogen Planâ€, announcing that it will invest 1.2 billion U.S. dollars in the research and development of hydrogen fuel cells and propose that in 2010, the share of fuel cell vehicles will account for 25% of the entire automotive market. The development target proposed by the Ministry of Economy, Trade and Industry of Japan is to reduce the price of fuel cells for automobiles to the level of ordinary gasoline engines before 2010, and it is necessary to first popularize fuel cell vehicles from government departments. ——— Xinhua News Agency, Beijing, August 25, Yang Ming
