摘要
EGR技术作为一种有效降低NOx排放的方法而得到广泛应用,EGR 系统能否正常工作直接影响发动机的排放效果.国六法规要求,OBD(车载诊断系统)需要对 EGR 系统的相关失效进行监测.本文介绍了满足国六法规要求的EGR系统诊断功能及其原理,为发动机电控系统诊断策略开发提供参考.
Abstract
EGR technology as a kind of effective method to reduce Nox emissions is widely used.The normal operation of EGR system directly affects the emission effect of engine.CHINA Ⅵ requires oBD(on-board diag-nostic system)to monitor EGR system failures.In this paper,EGR system diagnosis function satisfied the re-quirement of CHINA Ⅵ and its principle were introduced,which provide reference for engine electronic control system diagnosis strategy development.
