According to foreign agency forecasts, the total size of the global automotive market will increase by 39% during the 15 years from 2001 to 2014, of which gasoline vehicles will increase by 23% and diesel vehicles will increase by 97%. Due to its remarkable fuel-saving effect and ability to meet stringent exhaust emission standards, diesel vehicles have been highly valued in many countries (mainly the European Union, the United States, South Korea, and India) and have taken measures to encourage the development of diesel vehicles. These countries first identified the strategic positioning of diesel technology in automotive energy-saving technologies. For example, the EU has consistently encouraged the development of advanced diesel technologies and advanced gasoline technologies to increase the efficiency of conventional fuel vehicles; the US government changed its previous vague attitude towards diesel technology in 2005. President Bush once said that if the proportion of diesel cars in the United States is raised to 20%, 300,000 barrels of crude oil can be saved each day. Followed by the implementation of fuel tax policy. Some countries adopt a differential tax rate to make diesel prices lower than gasoline (more common in EU countries). For example, the price of diesel in South Korea is equivalent to only 75% of gasoline. Although the price of diesel vehicles is higher than that of gasoline vehicles by 10% to 15%, it is due to the cost of use. Low, diesel cars have achieved rapid development at the initial stage. The third is to implement vehicle tax incentives and even purchase subsidies for diesel vehicles. For example, between January 1, 2006 and December 31, 2010, the United States can purchase diesel cars for a tax return of up to $3,400. The same policy preferences for power cars. Different countries have differences in their encouragement policies or trade-offs. Countries such as the United States and South Korea, which are in their infancy, have much stronger policy support. At present, China’s diesel vehicles account for 23.7% of car ownership and only 0.2% of car ownership. In the first quarter of 2005, diesel vehicles accounted for 1.3% of newly registered passenger cars, far below the EU 50. %s level. We expect that China's car ownership will reach 60 million vehicles and 150 million vehicles in 2010 and 2020, respectively. If 2020, the proportion of diesel vehicles in passenger vehicle occupancy is assumed to be 10%, 20%, and 30%. The corresponding proportion of total vehicle ownership is 21.6%, 30.7%, and 39.7%. Then, the three scenarios could save 9.36 million tons of crude oil, 18.87 million tons and 28.37 million tons of crude oil in 2020, reduce automobile oil by 3.3%, 6.7%, and 10.1%, and reduce oil imports by 3.7% and 7.5% respectively. 11.3%. In particular, if a high-level plan is applied, the external dependence on reducing the use of automobile oil and reducing oil is more than 10%, and the fuel-saving effect is very significant. From the perspective of diesel fuel supply capacity, it is not an insurmountable constraint. In recent years, the development of new energy technologies for automobiles has been rapid, and new technologies and concepts, such as fuel cells, hybrids, electric vehicles, natural gas vehicles, and alcohol automobiles, continue to impact people's minds. The mainstream view of domestic and foreign experts is that in the first half of the 21st century, internal combustion engines and hybrid, gas and fuel cells, and pure electric vehicles will coexist for a long time, showing the characteristics of technological diversification. In 2020, traditional internal combustion engine cars will still account for about 30% of the total. Advanced internal combustion engines and hybrid vehicles will account for about 65%. The rest will be pure electric vehicles, gas and fuel cell vehicles. In addition, the industrialization of fuel cell vehicles still has a long way to go. In this context, it is recommended that China's auto energy strategy adopts the principle of technological diversification and clear two goals: First, we must continuously improve the fuel efficiency of traditional fuel vehicles, develop advanced diesel engine technology and advanced gasoline technology; Second, we must develop alternative fuel technologies. And new energy vehicles, the development of hybrid, electric vehicles and other technologies.
