1台ZL30型装载机在工作中突然发生自动熄火故障。之后多次启动,均不能着车。检查该装载机所配的4135型柴油机燃油供给系统、电路系统及油底壳内的机油,均正常。但在检查水散热器时,发现其内部冷却液面下降,且曲轴不能完成360°旋转。卸下柴油机4个喷油器,按下启动开关,发现从Ⅲ、Ⅳ缸喷油器安装孔内喷出冷却液,之后曲轴转动正常。初步判断,由于Ⅲ、Ⅳ缸汽缸盖垫漏水,造成冷却液进入活塞顶部燃烧室,导致活塞不能上、下运行以及曲轴
A Taiwan ZL30 loader sudden failure of the automatic shutdown at work. After several starts, can not drive. Check the loader with the 4135 diesel fuel supply system, the circuit system and the oil pan, are normal. However, when inspecting the water radiator, it was found that the internal coolant level dropped, and the crankshaft could not complete 360 ° rotation. Remove the four diesel injectors, press the start switch and found that from the Ⅲ, Ⅳ cylinder injector installation hole jet coolant, crankshaft rotation after normal. Preliminary judgments, as Ⅲ, Ⅳ cylinder head gasket leakage, resulting in coolant into the top of the piston chamber, resulting in the piston can not run up and down and the crankshaft
