The reasons for the unstable frequency of diesel generator sets after starting:
1. Air enters the fuel supply system's oil circuit, causing unstable diesel engine speed
2. There is a blockage in the oil circuit
3. The uneven fuel supply of each sub pump in the high-pressure oil pump results in different detonation forces of diesel during combustion in the combustion chamber
4. The poor atomization of the fuel injector inside the cylinder results in different detonation forces of diesel during combustion in the combustion chamber
5. The stability adjustment component inside the AVR control board is damaged
6. Poor contact or short circuit fault in the contact parts of each circuit
The above Huaquan Power has provided a brief introduction, hoping to provide users with reference.
