实例一 故障现象:一辆光阳125型摩托车,在平坦的路面上行驶时,一切正常,只要遇到凸凹不平的路面时,发动机便会自动熄火。 故障分析与排除:经过试车后发现,熄火后,只要车辆不继续颠簸,便可立即启动,这说明发动机本身无任何故障,产生故障的原因与点火系统有关。由于此车型属于坐式车,其发动机采用悬浮方式与车体连接,当车辆在不良路况上行驶时,发动机剧烈地颠簸,同时车体与发动机相互连接的电气线路便会受到不同程度的影响。因此,点火系统中的插头、线路很有可能出现
Example A failure phenomenon: a Gwangyang 125 motorcycle, driving on a flat road, everything is normal, as long as the uneven surface of the road, the engine will automatically turn off. Failure Analysis and Troubleshooting: After the test found that after the flameout, as long as the vehicle does not continue to bumpy, you can immediately start, indicating that the engine itself without any failure, the cause of the fault with the ignition system. Since this model belongs to the semitrailer, the engine is suspended and connected to the vehicle body. When the vehicle is driving in bad traffic conditions, the engine is vigorously bumpy and the electrical connections between the vehicle body and the engine are affected to varying degrees. Therefore, the ignition system plug, the line is likely to appear
