Basically, the unit operates unevenly at low speeds, and the exhaust pipe emits black smoke and makes abnormal noises at high speeds. Insufficient power of the generator unit before reaching major repairs is generally caused by problems in the fuel supply system and insufficient cylinder compression force.

這個時候就先空車檢查，如果加大油門，空車可以達到高轉(zhuǎn)速就是故障在工作機械，如果空車轉(zhuǎn)速上不去就代表故障在發(fā)電機組。

At this point, check the empty car first. If you increase the throttle, the empty car can reach its maximum speed, indicating that the fault is in the working machinery. If the idle car speed does not increase, it indicates that the fault is in the generator set.

檢查排氣歧管根部的溫度，如果溫度過低就是這個缸不工作或者是工作不良，低速時可用手指觸摸檢查，高速的時候就不要這樣做了，免得燙傷手指，這個時候就可以向排氣歧管的根部吐唾液，如果唾液沒有發(fā)出那種被高溫蒸發(fā)的聲音就代表這個缸壞掉了。

Check the temperature at the root of the exhaust manifold. If the temperature is too low, it indicates that the cylinder is not working or is not working properly. At low speeds, you can touch it with your fingers to check. At high speeds, do not do this to avoid burning your fingers. At this point, you can spit saliva at the root of the exhaust manifold. If the saliva does not make the sound of being evaporated by high temperature, it means that the cylinder is broken.

3、自動熄火

3. Automatic flameout

自動熄火的原因太多了，但是常見的基本就是燃油供給中斷和運動件受阻這兩個問題。

There are too many reasons for automatic shutdown, but the common ones are the interruption of fuel supply and the obstruction of moving parts.

在正常運轉(zhuǎn)的時候，如果，轉(zhuǎn)速慢慢的掉下來，聲音慢慢的變小，油溫、壓力、水溫都正常，推動油門沒有效果，延續(xù)一段時間后再慢慢的熄火，停車后用改錐能盤動飛輪就代表是燃油供給不暢或中斷。

During normal operation, if the speed slowly drops, the sound gradually decreases, and the oil temperature, pressure, and water temperature are all normal. Pushing on the throttle has no effect. After a period of time, slowly turn off the engine and use a screwdriver to turn the flywheel after parking, it means that the fuel supply is not smooth or interrupted.

在運轉(zhuǎn)過程中，水溫正常，機油壓力下降，油溫上升，油里面有金屬的碎片，有機油燒干的氣味，機器振動變快，聲音異常，轉(zhuǎn)速慢慢的降低，停車時慣性轉(zhuǎn)動時間短，停車后盤不動飛輪，機器降溫后還是盤不動飛輪那就可以確定是主軸燒瓦。

During operation, the water temperature is normal, the engine oil pressure drops, and the oil temperature rises. There are metal fragments in the oil, and there is a smell of engine oil burning dry. The machine vibrates faster, the sound is abnormal, and the speed slowly decreases. When parking, the inertia rotation time is short, and the flywheel cannot be turned after parking. If the machine still cannot be turned after cooling down, it can be determined that the main shaft is burnt.
