Causes that the Diesel Generator set cannot be started

2019-05-30

After several years of using, the Diesel Generator set will have some minor problems, such as failure to start normally. The prerequisite for the normal operation of the diesel Generator set is that the atomized diesel can be accurately and timely in the combustion chamber, and the compressed air in the combustion chamber should be reached. Sufficient temperature to catch fire and break out. Today, we analyze why there are no reasons why diesel generator sets cannot be started.

1. There is no oil in the fuel tank or the fuel valve is not open.

2. The oil system blockage of the fuel system causes the unit to not come to the oil.

3. There is moisture in the fuel and it is not easy to catch fire.

4. Air is introduced into the fuel supply system of the generator set to reduce or not supply oil.
5. The temperature in the combustion chamber and the cylinder is too low or the injection quality of the injector is not good, so that the fuel atomization is not good, and it is difficult to form a combustible mixture, so it is difficult to start.
6. The high pressure oil pump has insufficient oil supply and the oil supply pressure is too high or too low.
7. The unit injection time is too early or too late.
8. The generator set starts to run out of battery power, the controller is not energized, and the start relay is faulty.
9. The preheating is insufficient before starting, and the unit is in a low temperature state.
10. Diesel generators use fuel of the wrong type or grade.
11. The oil pump is faulty.

12. The unit starts to have insufficient battery capacity.
