引起喷油泵供油不均的原因,主要是调试不当和机件故障;可通过排气温度、单缸断油以及喷油器喷油量来诊断;出现喷油泵供油不均后,就机可采取调整供油齿圈,排放供油系统空气和对柱塞偶件进行检修等办法予以排除。

The main cause of uneven fuel delivery of injection pump is unsuitable test and trouble components, which can be diagnosed by delivery temperature, oil cut - off on single - cylinder and oil mass of injection pump, and which can be solved by adjusting oil supply gear ring, releasing air of oil supply system and repairing plunger coupled parts.
