车用发动机电控式EGR系统设计解析

The Analysis of Electronic Cotroling EGR System

车用发动机的有害排放物是造成大气污染的一个主要来源,随着环境保护问题的重要性日趋增加,降低发动机有害排放物这一目标成为当今世界上发动机发展的一个重要方向。通过对车用发动机废气再循环(EGR)系统的控制方法设计的解析,说明在安装一套排气再循环EGR控制系统是有效降低车用发动机有害排放物的行之有效的方法。

Motor vehicle emission has become a major origin of the atmosphere polution. With the increase of the importance to protect the environment,cutting down the motor vehivle emission has become a important target of world＇s engin development today. This article reveal setting up a control system of Exhaust Gas Re-circulation（EGR） is an effective way to cut down the engin emission by the analysis of EGR.
