Fault in The Oil Supply System of Generator Set

Nov. 02, 2023

The inability to successfully start the generator set three times in a row at an ambient temperature of 5℃ or above is referred to as difficulty in starting. There are two main reasons for the difficulty in starting, one is battery issues, but rather oil supply system faults. Now let's take a look at the specific oil supply system faults.

There is a malfunction in the oil supply system of the generator set:

1. There is no oil in the fuel tank or the fuel tank switch is not opened, resulting in cracking or collapse of the fuel tank.

2. Diesel fuel has poor quality and contains a lot of water.

3. When the ambient temperature is below 5 ℃, improper engine and diesel grades are used, resulting in high viscosity of the engine and diesel, and high starting resistance torque of the diesel engine crankshaft, making it difficult to start.

4. The diesel filter of the generator set is blocked at the inlet pump.

5. There is air in the fuel supply system, causing poor fuel supply.

6. Incorrect fuel supply advance angle, insufficient fuel supply, unable to start.

7. The fuel injector is damaged, with low injection pressure, poor dripping and atomization.

8. The high-pressure oil pipe joint is not tightly sealed or the high-pressure oil pipe is damaged and leaking, making it unable to start.

9. There is a malfunction in the fuel injection pump, such as wear of the outlet valve and plunger coupling, fracture of the outlet valve spring and plunger spring, etc., which causes the fuel injection pump to not supply oil.
