Automobile dieselization process accelerates
The rising fuel price has promoted the process of dieselization of automobiles. The light passenger car, which was originally powered by gasoline engines, showed the phenomenon that diesel vehicles sold more than gasoline vehicles for the first time in the first half of 2006. This trend is still continuing.
Several domestic backbone diesel engine companies have also developed diesel engines for passenger cars (sedans and mini-cars), which has changed the situation that the original passenger car diesel engines are basically monopolized by foreign diesel engines. At present, domestically produced medium and heavy duty diesel engines are mainly domestic brands, and basically have independent intellectual property rights. Passenger car diesel engines are mainly foreign brands, and basically rely on imports. Only some low-end products use domestic diesel engines, and light-duty diesel engines are Chinese and foreign. Joint ventures and domestic brands are combined.
After several years of rapid development, several domestic companies with strong technical strength and capital have emerged, such as Weifang Diesel Engine Company, Yulin Diesel Engine Company, Shanghai Diesel Engine Company, Wuxi Diesel Engine Factory, Dalian Diesel Engine Factory, Chaoyang Diesel Engine Factory and Yunnan Internal Combustion Engine Factory. In addition, its sales volume, sales revenue and production scale are very impressive. Foreign advanced diesel engine technologies such as high pressure injection, supercharged intercooler, variable section supercharger, four-valve technology, electronically controlled fuel injection technology, emission control technology, etc. have been promoted and applied in China, and the power and fuel consumption rate of diesel engines The emission performance, reliability and other indicators have been greatly improved, and the transition from traditional mechanical products to mechanical and electronic technology products has begun. However, compared with the advanced level of Europe and the United States, there is still a big gap, mainly because there is no core technology for diesel engines. For example, the technology of electronic fuel injection systems is still monopolized by foreign companies. The independent research and development and innovation capabilities are still weak, and product development mainly relies on cooperation with foreign design companies. In addition, although the passenger car diesel engine has been developed, it has not been put on the market, and is only used on some low-end light buses and SUVs.
In the past few years, the domestic diesel engine industry has developed rapidly, but it should be clearly recognized that although the domestic diesel engine production scale is very large, the technical level of most domestic diesel engine products is still low, and the research and development strength of domestic diesel engine enterprises is still weak. Most of the research and development of new products relies on foreign companies, so China is currently only a major manufacturing country for diesel engines, and it is not a manufacturing power.
Electronic control fuel injection technology made a breakthrough
The international diesel engine-controlled fuel injection system is developed and produced by a strong professional production plant, such as Bosch in Germany, Denso in Japan, and Delphi in the United States. In the past, there was no domestic component manufacturer capable of developing and producing electronically controlled fuel injection systems. Fortunately, in recent years, China has made major breakthroughs in the development of the weakest diesel-electric fuel-controlled fuel injection system technology, such as Chengdu Witt. In 2004, EFI and Tsinghua University successfully developed an electronically controlled unit pump system with independent property rights. In the same year, it began to provide complete sets of products for heavy-duty vehicles. Now it has provided thousands of sets of products and became the first in China. The enterprises that produce diesel electromechanical fuel injection system products have broken the monopoly of foreign companies. FAW Group Wuxi Oil Pump Nozzle Research Institute has successfully developed its first generation of electronically controlled common rail fuel injection system with independent property rights, but it has not yet been applied commercially.
