(1)一台 S1100型柴油机启动困难,机手自己在家修理。但是修理效果不佳,修前仅是启动困难,修后却根本不能启动,修前还能听到清脆的喷油声,修后却听不到这种声音,于是拆下喷油泵和喷油器请求检验。经查,二者状态良好,不需要更换。但是机手回去装上后,仍听不到喷油声。笔者到机手那里,打开齿轮室盖检查,发现机手更换了调速齿轮衬套,但却没有压到位(相差4 mm),致使加大油门时柱塞调节臂行程太小,喷油泵不供油。将该衬套压到位后,故障排除。
(1) A S1100 diesel engine is difficult to start and the crew repairs at home. But the repair is not good, repair before the start-up is difficult, but after repair can not start, before the repair can hear the crisp sound of injection, after repair but can not hear this sound, so remove the fuel injection pump and injection Request verification. The investigation, both in good condition, do not need to be replaced. However, after the driver returned to install, still can not hear the fuel injection sound. I went to the hands there, open the gear room cover inspection and found that the hands of the speed change gear bushing replacement, but did not put pressure in place (a difference of 4 mm), resulting in increased throttle when the plunger arm stroke is too small, the pump is not Oil supply. Press the bushing in place, troubleshooting.
