一辆小松挖掘机装用三菱S6D110型柴油机,在气温较低时,柴油机冷启动性能变差,刚着车时,排气管尾部黑烟较少。该柴油机装配启动电磁阀,功能是在启动柴油机时加大喷油泵的供油量,使喷入汽缸内的燃油增多,将可燃混合气变浓以提高启动性能。若冷天难启动,应先怀疑电磁阀工作不良。拔下启动电磁阀插接器,将试灯一端接黄色线,另一端搭铁。按下手启
A Komatsu excavator equipped with Mitsubishi S6D110 diesel engine, the temperature is low, the diesel engine cold start poor performance, just the car, the tail of the exhaust pipe less smoke. The diesel engine is equipped with a solenoid valve. The function of the diesel engine is to increase the fuel supply of the fuel injection pump when starting the diesel engine, increase the fuel injected into the cylinder, and enrich the combustible mixture to improve the starting performance. If it is hard to start cold, should first suspect the solenoid valve is not working properly. Unplug the start solenoid valve connector, the test light at one end of the yellow line, the other end of the ground. Press the hand Kai
