Because the old oil of the unit is used for a long time, it becomes thinner and thinner, so there are more and more carbon deposits. Thin oil is easy to leak oil, resulting in more and more carbon deposits and a lot of power loss. When the new oil is replaced, the diesel generator cannot adapt to the viscosity of the oil, which may increase the speed, resulting in a loud noise of the generator.

Maintenance:

1. Cleaning: Regularly clean the dust and debris on the surface of the unit and keep it well ventilated.

2. Oil replacement: Replace the oil according to the specified time and mileage to ensure the lubrication of the engine.

3. Filter cleaning and replacement: The air filter, fuel filter and oil filter should be cleaned or replaced regularly to prevent impurities from entering.

4. Battery maintenance: Check the battery power and electrolyte level, keep the electrodes clean, and tighten the connection lines.

5. Cooling system inspection: Ensure that the radiator is not blocked, the coolant circulates normally, and prevent the engine from overheating.

In short, regular repairs and maintenance can effectively reduce the failure rate of diesel generator sets and improve their working efficiency and stability.
