喷油器喷油不正常,会造成喷射压力低、雾化不良、燃烧不完全、排气冒烟、喷孔积炭、机器过热、油耗增加,混合气形成不好、喷油嘴磨损加快。柴油机喷油不正常,归纳起来可分3种情况。一、喷油器2次喷射喷油器1次喷油终了,针阀关闭以后,可能重新开启,发生2次喷射。2次喷射是高压油管中的压力波动引起的。当油泵供油结束,泵室内迅速出现低压波,出油阀快速降落,在泵端高压油管中出现一负压
Injector injection is not normal, will result in low injection pressure, poor atomization, incomplete combustion, exhaust smoke, spray holes coke, the machine overheating, fuel consumption increases, the formation of gas mixture, injector wear and tear accelerated. Diesel injection is not normal, can be summed up in three cases. First, the injector 2 injection injector 1 injection end, the needle valve closed, it may re-open, 2 injection occurred. The second injection is caused by pressure fluctuations in the high pressure tubing. When the oil pump ends, the pump room quickly appeared low-pressure wave, the valve quickly landed in the pump side of the high-pressure tubing in a negative pressure
