The Development and Current Situation of Electronically Controlled Fuel Injection System of Diesel Engine for Vehicle

电子控制技术是车用柴油机燃油喷射系统发展的必然趋势。本文简述了车用柴油机采用电控燃油喷射系统的必要性及其组成，分析了国内外柴油机电控燃油喷射系统的发展及应用实例。并着重介绍了电控泵喷嘴和高压共轨电控燃油喷射系统。

Electronically controlled fuel injection is the trend of development of the fuel injection. Necessity of adopting electronically controlled fuel injection and its constitution are briefly described. At the same time the recent development and some practical examples are analyzed in this paper. At last the electronically controlled unit injection system and the electronically controlled injection system of the common rail forms are introduced in detail.
