点火系统和供油系统故障是发动机的常见故障,特别对电控发动机而言,当发动机不能起动或易熄火时,究竟是点火系统故障还是燃油喷射系统故障或其他系统的故障,往往是维修中首先要判定的问题。现以典型进口电控汽车为例,阐述电控发动机电子点火系统的故障诊 Ignition system and fuel system failure is a common engine failure, especially for electronically controlled engines, when the engine can not start or easy to turn off, whether the ignition system failure or fuel injection system failure or other system failure, often in maintenance First of all to determine the problem. Now taking the typical imported electronic control car as an example, it expounds the fault diagnosis of electronically controlled engine electronic ignition system
