1.汽油机无法起动汽油机无法起动不外乎有三大原因:燃料系统的毛病、电路系统的毛病和气缸压缩力不够。一般情况下,三大毛病不会同时发生。因此,当一台机器无法起动时,首先应判断故障原因,确定故障出在哪一个系统中,然后采取措施。可按下列步骤进行检查。 (1)首先用手转动起动轮,转过上止点时,感到比较费力,转过上止点后起动轮可以自动转过一个较大的角度,说明压缩力正常。对于新机器或大修后的机器,一般情况下压缩力是正常的。 (2)起动时气缸内无爆发声,排气管排气无力,排出的气体干燥无味,出现这种现象大多说明油路系
1. Gasoline engine can not start Gasoline can not start there are three major reasons: the fuel system problems, circuit system problems and cylinder compression is not enough. Under normal circumstances, the three major problems will not happen at the same time. Therefore, when a machine can not start, we should first determine the cause of the malfunction, determine which system the fault belongs to, and then take measures. Can follow the following steps to check. (1) First, turn the starter wheel by hand, turn over the top dead center, feel more strenuous, turn the top dead center after the start wheel can automatically turn a larger angle, indicating normal compression. For new machines or overhaul machines, compressive forces are generally normal. (2) There is no explosion sound inside the cylinder at start-up, the exhaust pipe is exhausted exhaustless, the discharged gas is dry and tasteless, and most of this phenomenon shows that the oil system
