1. The governor does not reach the minimum speed.

排除方法：對高壓油泵上部4個汽缸的高壓油管逐個進行斷油試驗，結果發現第三缸斷開后排藍煙現象消失。停機后，拆卸第三缸噴油器，對噴油器進行噴油壓力試驗，結果發現第三缸噴油嘴偶件發生滴油現象且量很少。

Troubleshooting: the high-pressure oil pipes of the upper four cylinders of the high-pressure oil pump were cut off one by one, and the results showed that the blue smoke disappeared after the third cylinder was cut off. After shutdown, the third cylinder injector was disassembled and the injection pressure test was carried out. The results showed that the third cylinder injector had little oil dripping.

2、發電機組各汽缸工作不良，導致各缸壓縮壓力不同。

2. The bad working of each cylinder of the generator set results in different compression pressure of each cylinder.

排除方法：對柴油機油底殼內的機油標尺進行檢查，觀察是不是機油黏度太低或機油量太多，使機油進入燃燒室后且蒸發成油氣未燃燒而從排氣管排出。但通過檢查發現機油的質量和數量符合柴油機的用油規定

Troubleshooting: check the oil gauge in the diesel oil pan to see if the oil viscosity is too low or the amount of oil is too much, so that the oil enters the combustion chamber and evaporates into oil gas, which is not burned and discharged from the exhaust pipe. However, it is found that the quality and quantity of engine oil meet the requirements of diesel engine

3、調速器內部調速彈簧彈力減弱，使調速性能發生變化。

3. The elastic force of the speed regulating spring inside the governor is weakened, which changes the speed regulating performance.

排除方法：起動柴油發電機組后使轉速提高到1000r/min左右，觀察轉速是不是有所穩定，但聽到發電機組轉動的聲音還是不穩定，故障未被排除。

Troubleshooting: after starting the diesel generator set, increase the speed to about 1000r / min, observe whether the speed is stable, but hear the sound of the generator set rotating is not stable, the fault has not been eliminated.
