Three major reasons why diesel generator sets cannot start normally

Recently, many users have reported that diesel generators have difficulty starting or even cannot start after running continuously for a period of time. What is the reason for this? Regarding this issue, professional technicians will teach you to conduct self inspection from three aspects:

（1） Fuel system malfunction refers to blockage in the fuel system, or due to air in the fuel system, fuel pump failure or intermittent fuel supply, etc.

（2） Insufficient compression pressure in diesel generator sets is mainly caused by wear and tear of piston rings and cylinder liners, adhesive buildup on piston rings, valve leakage, or low temperature during compression.

（3） Electrical equipment malfunction may be caused by battery depletion, poor contact of power supply wiring, failure or weakness of the starter motor, resulting in the diesel generator set being unable to start normally.

The reasons why diesel generator sets cannot start normally are mainly due to the above situations. You can investigate the causes of the faults one by one and replace or disassemble the worn parts according to the reasons to clean the generator. Only by identifying the faulty area can the problem be solved as soon as possible, ensuring the normal start-up and operation of the diesel generator set.
