采用经验法确定低压油路的漏气部位,是依据发动机工作状态来判别的。当发动机在工作中因供油管路中进入空气而自行熄火时,其漏气部位在输油泵至油箱的油管或接头处。这是因为发动机工作时,输油泵至喷油泵的油管压力高于 Empirical method to determine the low-pressure oil leaks, is based on the engine to determine the working conditions. When the engine at work because of the oil into the air line and turn itself off, the leak in the pump to the fuel tank or pipe joints Department. This is because the engine work, the pump to the fuel pump tubing pressure is higher than
