四、积极引进和开发轿车用柴油机近几年来,汽油机采用了提高压缩比,使用电子喷射系统代替化油器等先进方法来提高汽油机的优越性,但一些先进技术同样也被应用在柴油机上,使轿车柴油化也有明显增长的势头,轿车使用柴油机的比重与日共增。我国的柴油资源比汽油资源更丰富些,加上轿车柴油化的一些优越性,因此引进和开 Fourth, the active introduction and development of sedan diesel engine In recent years, the gasoline engine used to improve the compression ratio, the use of electronic injection system instead of carburetor and other advanced methods to improve the superiority of the gasoline engine, but some advanced technologies are also used in diesel engines, Diesel car also has a significant momentum of growth, the proportion of cars using diesel engines and Japan shared. China’s diesel oil resources more abundant than gasoline resources, coupled with some of the superiority of car diesel, so the introduction and opening
