故障现象:一辆AX100型摩托车,挂四挡正常行驶中,发动机突然熄火,连踏启动杆仍不能启动发动机。 故障分析排除:对突然熄火的故障,一般应先考虑两个方面,即油路和电路。检查油路,该车燃油开关处于开启状态,拔下化油器进油胶管,有燃油流出,证明油路畅通。检查高压线跳火情况,火花正常。取下火花塞试火,火花塞无火。进一步检查发现,有一块状积炭卡在了火花塞主电极与侧电极之间,致使电极短路,火花塞不跳火。将积炭清除,车子启动恢复正常。
Symptom: An AX100 motorcycle, hanging block the normal driving, the engine suddenly turn off, even with the start lever still can not start the engine. Troubleshooting Analysis: Failure of a sudden flameout, the general should first consider two aspects, namely the oil circuit and the circuit. Check the oil, the car fuel switch is turned on, unplug the carburetor into the hose, a fuel outflow, that the oil flow. Check the high-voltage line flashover, spark normal. Remove the spark plug test fire, spark plug without fire. Further examination found that there was a piece of coke stuck in the spark plug between the main electrode and the side electrode, causing the electrode short circuit, the spark plug does not jump fire. Coking clear, the car started to return to normal.
