Diesel characteristic of the work itself is its low-emission engines. Modern diesel engines generally use EFI, common rail, turbocharged technology in the cold in the lower weight, noise and smoke control has been made a major breakthrough, reaching the level of gasoline engine, and exhaust HC, CO and CO2 content of less than gasoline engine and gas engine. China caused some cities to prohibit diesel vehicles culprit - Soot, by increasing injection pressure has been the method has been effectively resolved. New diesel particulate emissions reduced by 90%, generally 16 to 21, while gasoline engine only 7-10. Diesel is far greater than the thermal efficiency of gasoline engines, low fuel consumption than gasoline engine about 20 percent, CO2 emissions compared with gasoline engines also much lower. China calls for a new driving force for China's automotive diesel engine vehicles, the total production of the Toyota Motor Corp. of Japan only one year yield. Internal Combustion Engine Industry there is a more serious structural shortage, caused by diesel vehicle market has become a gap in the domestic market. Throughout China's history of the development of diesel-powered, in the 20th century, in the late 1980s, mainly to the diesel-powered heavy-duty trucks starting in China, so far the heavy-duty trucks have been used 100% of the diesel-powered, and 90% of large Nez injecteurs have been. Minibuses still in the area mainly to petrol-powered, homemade minibuses only use diesel-powered Nanjing Iveco, other models are used petrol Evidently incomplete varieties of products in China is one of the weaknesses automotive products.
