汽车发动机电控系统故障探讨

An Investigation into Faults of Electronic Control of Automobile Engine System

汽车发动机电控系统中电器元件产生故障的三个常见方面:线路故障、元件老化与元件击穿。能准确判断故障现象,查找故障原因,正确使用相关的检测方法和手段,熟练应用汽车万用表和汽车故障解码仪,并掌握发动机各系统的工作原理,才可以更好地判断和修复电控发动机的故障。

This paper analyzed three common aspects with respect to the fault of electronic control system of automobile engine,including circuit fault,components＇ aging and components＇ breakdown.To accurately judge fault,find out the causes,properly apply relevant testing methods and means,skillfully apply automotive multimeter and fault decoding device,and master the working principle of the systems of engine can better judge and repair the faults of electronic-controlled engine.
