柴油机的燃油系一旦有空气进入,轻则发动机难以启动或运转不稳,重则可能抛锚于路中,尴尬难堪。下面以最常见的柱塞泵燃油供给系统为例,介绍排除方法。1油路中有空气进入的症状空气具有很大的可压缩性和弹性。当油箱至柴油机输油泵段油管存在漏点,产生漏气时,空气将会渗入,从而 Once the fuel system of the diesel engine enters the air, it is difficult for the engine to start or operate unstablely, and may end up in the road with embarrassment and embarrassment. The following to the most common plunger pump fuel supply system, for example, describes the exclusion method. Symptoms of air entering the circuit 1 The air is highly compressible and resilient. When the tank to the diesel engine oil pump section pipe leakage point, resulting in leaks, the air will infiltrate, and thus
