The power drop during the use of generator sets is mostly caused by insufficient fuel supply and insufficient air supply.

燃油供给不足

Insufficient fuel supply

1、发电机组低压油路供油不畅的原因是：油箱油量不足；油箱盖通气孔堵塞；油箱出口滤网堵塞，油箱开关堵塞或开度不够；滤清器堵塞。

1. The reasons for the poor oil supply of the low-pressure oil circuit of the generator set are: insufficient oil in the oil tank; The vent hole of the fuel tank cover is blocked; The filter screen at the outlet of the oil tank is blocked, and the oil tank switch is blocked or the opening is not enough; The filter is blocked.

2、发电机组喷油泵供油不足的原因是：柱塞及出油阀磨损，引起泄漏；出油阀垫不严密引起泄漏；油泵滚轮及供油凸轮磨损使供油有效行程变小等。

2. The reasons for the insufficient oil supply of the fuel injection pump of the generator set are: the plunger and oil outlet valve are worn, causing leakage; The oil outlet valve gasket is not tight, causing leakage; The wear of oil pump roller and oil supply cam reduces the effective stroke of oil supply, etc.

3、发电机组喷油器喷油少的原因是：喷油器针阀偶件磨损，使回油增多；喷油压力过高，喷油延续时间短，喷油器回油管堵塞等。喷油器回油增多和不回油的检查方法：拧松喷油器回油管接头螺丝，如有较多不断流出，说明针阀磨损，应予以更换。如果回油管

3. The reason why the fuel injector of the generator set injects less fuel is that the needle valve coupling of the fuel injector is worn, which increases the return oil; The injection pressure is too high, the injection duration is short, and the fuel injector return pipe is blocked. Inspection method for increased return oil and no return oil of the fuel injector: loosen the connector screws of the fuel injector return pipe. If there is more and more continuous outflow, it indicates that the needle valve is worn and should be replaced. If the oil return pipe

不回油，会使喷油器上腔燃油增多，压力增大，针阀在打开时上行阻力大，导致喷油器工作性能恶化，应清理堵塞物。

If the fuel is not returned, the fuel in the upper chamber of the injector will increase, the pressure will increase, and the upward resistance of the needle valve will be large when it is opened, resulting in the deterioration of the working performance of the injector. The blockage should be removed.

空气供给不足

Insufficient air supply

1、发电机组空气滤清器堵塞：观察康明斯发电机排气管，如果在空转时冒黑烟，或稍加负荷就冒黑烟，表明气缸进气不足，致使喷入的不能完全燃烧，应清洗或更换滤芯。

1. The air filter of the generator set is blocked: observe the exhaust pipe of Cummins generator. If black smoke is emitted during idling or with a little load, it indicates that the air intake of the cylinder is insufficient, so that the injected air cannot be completely burned. The filter element should be cleaned or replaced.

2、发电机组的气缸压力不足：气缸压力不足多为气缸漏气引起，要重点对其气缸进行维修。

2. Insufficient cylinder pressure of generator set: the insufficient cylinder pressure is mostly caused by cylinder leakage, and the maintenance of its cylinder should be focused.
