Energy-saving and environmentally-friendly advanced diesel engine technology is highly valued by all countries

According to forecasts from relevant foreign institutions, the total size of the global automotive market will increase by 39% in the 15 years from 2001 to 2014, with gasoline vehicles increasing by 23% and diesel vehicles by 97%.

Due to its remarkable fuel-saving effect, diesel vehicles can meet the stringent emission standards, and have been highly valued by many countries (mainly including the European Union, the United States, South Korea, India, etc.) and have taken measures to encourage the development of diesel vehicles. These countries firstly clarified the strategic positioning of diesel technology in automotive energy-saving technologies. For example, the EU has always encouraged the development of advanced diesel technology and advanced gasoline technology to improve the efficiency of traditional 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 increases to 20%, 300,000 barrels of crude oil per day can be saved. The second is to implement a fuel tax policy. Some countries adopt differential tax rates to make diesel prices lower than gasoline (common in EU countries). For example, South Korea's diesel price is only 75% of gasoline, although diesel prices are 10% to 15% higher than gasoline vehicles, but due to the cost of use. Low, diesel vehicles have achieved rapid development in the initial stage. The third is to implement a vehicle tax concession or even a subsidy policy for diesel vehicles. For example, from January 1, 2006 to December 31, 2010, the purchase of diesel cars can receive a tax return of up to $3,400. The same policy offers for power cars. Different countries have different incentive policies or trade-offs. In countries where the United States, South Korea, etc. are in their infancy, policy support is much stronger.

Diesel fuel saving effect is remarkable

At present, the proportion of diesel vehicles in China is 23.7%, and the proportion of car ownership is only 0.2%. In the first quarter of 2005, diesel vehicles accounted for 3% of newly registered passenger cars. At the level of 50% in the EU. We expect that China's car ownership will reach 60 million and 150 million vehicles in 2010 and 2020, respectively. If the proportion of diesel vehicles in passenger car ownership in 2020 is assumed to be 10%, 20% and 30%, the corresponding proportion of total car ownership is 21.6%, 30.7% and 39.7%. Then, the three scenarios can save 9.36 million tons, 18.87 million tons and 28.37 million tons of crude oil in 2020; they can reduce oil consumption by 3.3%, 6.7% and 10.1%; and reduce oil imports by 3.7%, 7.5% and 11.3%. In particular, if this solution is applied, the external dependence of reducing oil consumption and reducing oil is more than 10%, and the fuel saving effect is very significant. From the perspective of diesel supply capacity, it is not a constraint that cannot be overcome.

In recent years, new energy technologies for automobiles have developed rapidly. New technologies and new concepts such as fuel cells, hybrids, electric vehicles, natural gas vehicles, and alcohol-based vehicles continue to impact people's minds. The mainstream view of experts at home and abroad is that in the first half of the 21st century, internal combustion engines and hybrids, gas and fuel cells, and pure electric vehicles will coexist for a long time, presenting the characteristics of diversified technologies. In 2020, traditional internal combustion engine vehicles will still occupy about 30% of the total, and advanced internal combustion engines and hybrid vehicles will account for about 65%. The rest are 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 automotive energy strategy adopt the principle of technological diversification and clarify two objectives: continuously improve the fuel efficiency of traditional fuel vehicles, develop advanced diesel technology and advanced gasoline technology; develop alternative fuel technologies and new energy vehicles. Develop technologies such as hybrid power and electric vehicles.

Because of its maturity and practicality, advanced diesel technology does not require large-scale construction and transformation of related infrastructure. It is a shortcut to achieve energy conservation and environmental protection goals. The development of advanced diesel technology should be one of the important components of the automotive energy strategy. At the same time, two principles should be clarified: encourage the development of advanced diesel technology, rather than “old” diesel technology; the development of advanced diesel technology should be matched with the “cleaning” of diesel to significantly improve the quality of oil.

Experts suggest that by 2010, 2015, 2020, the proportion of advanced diesel passenger cars in the possession will increase from the current 0.2% to 5%, 15% and 30% respectively.

Develop appropriate incentives

Appropriate incentive measures include, first of all, in the “Eleventh Five-Year” automobile industry plan, it is recommended to explicitly encourage the development of advanced diesel vehicles. At present, there are a large number of policies or regulations restricting the use of diesel vehicles in many places. There is still a misunderstanding of advanced diesel vehicles. Most capable production enterprises are waiting to see if the policy is unclear. The central government clearly encourages the development of advanced diesel vehicles. Help to eliminate conceptual and local regulatory obstacles.
