文章结合世界各国机动车尾气排放的实施,阐述目前国内城市客车排放法规的实施情况,指出电控燃油喷射是实现国Ⅲ排放的关键技术。文中详细介绍了电控燃油喷射技术中的电控高压共轨系统和电控单体泵系统,并对两者特点进行比较。结合国内常用柴油发动机喷嘴系统配置,认为电控高压共轨系统应成为今后大中型柴油发动机的发展趋势。
Combing with the enforcement of sion standards rates domestic all over the enforcement world, the of emission vehicle emisarticle elabostandards on city bus and points out that electronic fuel injection is the key technology to realize 3 - class NAAQS （ national ambient air quality standard）. The article puts emphasis on the electronic high pressure common rail system and electronic unit pump system included in the electronic fuel injection technology, and compares their characteristics. Combing with the popular configuration of fuel injection system on domestic diesel engines, electronic high pressure common rail fuel injection system should be the trend of large and medium diesel engine in future.
