A Case Study of Short-circuit of Electronic-control Gasoline Engine

一辆2005年北京产的BJ6602G1客车，装配CA4G25E电控汽油机（4缸），出现无法启动故障。据车主介绍，此车在大修完1周后，出现加速无力和无怠速状况，多次启动后便已无法着车。

The coach BJ 6602G1 was produced in 2005, and was incorporated with electronic-control gas-oline engine model CA4G25E.Once the engine failed to start, and after examining and testing, it was found that a short-circuit inside of ECU happened that caused the failure of the engine. It restarted after the circuit was reconnected.
