1.搭接不良引起的启动困难 一辆北京BJ212车,起动时运转无力,启动困难,起动后低、中速还好,高速时消声器“发吐”、冒黑烟。经检查,原来是该车搭铁几处油污较多,加之锈蚀后松动,导致搭铁不良,电阻相应增大,启动时电流难以形成回路,以致出现上述故障。经过清洗油污,除去锈蚀,重新紧固搭接线,故障得以排除。 1. Difficult start caused by lap joint difficult Beijing BJ212 car, start running weakness, difficult to start, after starting low, medium-speed okay, high-speed muffler “hair spit”, black smoke. After examination, the original car is more than a few dirt on the ground, coupled with loose rust, resulting in poor grounding, a corresponding increase in resistance, start-up current is difficult to form a loop, resulting in the above failure. After cleaning the oil, remove the rust, re-fasten the lap, the fault can be ruled out.
