案例1故障现象一辆新购买的北方奔驰牵引车(采用潍柴WP10336发动机),驾驶人反映发动机动力不足,该车空载时故障现象不明显,但重载时挡位和发动机转速不匹配,尤其在上坡时出现车辆有耸车的现象,发动机故障灯点亮。故障诊断用WP-VDS100故障检测仪检测,显示为油路系统故障。首先检查位于车架上的燃油滤水滤芯,滤芯底部无水分,无杂质。再解剖检查发动机柴油粗、细滤芯,也均无堵塞。检查油箱出油管路,没有漏气及折弯的现象。最后拆检柴油箱中的燃油回油管,发现回油管粗滤网没有了,而改
Case 1 Trouble phenomenon A newly purchased North Benz tractor (using Weichai WP10336 engine), the driver reflects the lack of engine power, the car no load failure phenomenon is not obvious, but the heavy load and the engine speed does not match, Especially in the ascent when the vehicle has a towering phenomenon, the engine fault light lit. Fault detection WP-VDS100 fault detector detection, showing the oil system failure. First check the fuel filter on the frame of the filter, the bottom of the filter without water, no impurities. Anatomic examination of the engine diesel crude, fine filter, but also no blockage. Check the fuel tank outlet pipe, there is no leakage and bending phenomenon. Finally, seized the diesel fuel tank back to the pipe, found no return to the coarse filter net, and changed
