If the diesel generator set does not supply fuel as required, it will cause a variety of harms, mainly including the following aspects: ‌

‌1. Abnormal wear and difficulty in starting: When the fuel supply time is too early, the diesel engine may encounter difficulty in starting, and the crankshaft is easy to reverse, which may cause premature wear of the parts, power reduction and unstable idling. In this case, the abnormal noise may intensify when the accelerator pedal is pressed, and the abnormal noise may weaken or disappear as the speed increases. ‌

‌2. Increased fuel consumption and reduced power: Too late fuel supply time will cause the engine to overheat, the cooling water tank to boil, and the diesel consumption will also increase. At this time, even if the accelerator pedal is pressed, the speed cannot be increased quickly, and white smoke will come out of the exhaust, resulting in both economy and power. ‌

‌3. Emission problems: Incorrect fuel supply time will also affect emission quality. Too early fuel supply will cause incomplete combustion of diesel and produce knocking, which not only weakens power output, but also damages fuel economy, and increases the content of nitrogen compounds in emissions, posing a threat to the environment. ‌

 

‌4. Other symptoms‌: Incorrect fuel supply time can also lead to other symptoms, such as failed start, rough operation, weak output, white smoke and "raw oil" smell in exhaust, easy shutdown at low speed, etc.

 

‌In order to ensure the normal operation of the diesel generator set and extend its service life, the following measures need to be taken‌:

 

‌1. Regular inspection and maintenance‌: Regularly check whether the engine oil is sufficient to prevent cylinder pulling and tile burning caused by lack of oil‌.

‌

2. Accurately control the fuel supply time‌: Ensure the accuracy of the fuel supply time by adjusting the fuel supply advance angle to avoid premature or late fuel supply‌.

‌

3. Monitor noise and vibration‌: After the unit is successfully started, monitor whether there is abnormal noise and vibration, and whether the control interface has abnormal display‌.

 

Through the above measures, the harm caused by incorrect fuel supply time can be better reduced to ensure the stable operation of the diesel generator set.
