摘　　要：介绍了国外各种柴油机电控燃油喷射技术的发展历程、系统典型代表及各阶段的技术特点,阐述了我国应达到国Ⅲ排放标准的技术措施及所采用的电控和非电控燃油喷射技术的特点,指出目前我国采用的电控分配泵、电控泵喷嘴、电控组合单体泵、高压共轨及电控直列泵+冷却EGR等柴油机燃油喷射技术路线可以满足国Ⅲ排放法规的要求。This paper introduces the development course, representative system as well as technical characteristics of different kinds of electronically controlled fuel injection in other countries. By analyzing the features of the electronically controlled and non-electronically controlled fuel injections which have meet the requirements of China lIl emissions regulation, we know that electronically controlled distribution pump; electronically controlled unit pump, electronically controlled assembly pump, high-pressure common rail and electronically controlled in-line fuel pump with cooled EGR can meet the requirements of China Ill emissions regulation.
