How to Check The Low Pressure Oil Circuit of The Generator Set?

If you want to check whether the low-pressure oil circuit of the generator set is blocked, you can check that no abnormalities are found in the generator set. Remove the four fuel injectors on the cylinder head of the generator set, and then conduct an injection pressure test. The inspection results show that the first cylinder, the fuel injector, is not working and running; The third cylinder, fuel injection nozzle blowby; The fuel injection nozzles, injection pressure, and atomization requirements of the first and fourth cylinders meet the standards. The fuel injection nozzles of the first and third cylinders were replaced, and the fuel injection pressure was installed and debugged. After assembly and testing, it was found that the frequency of the generator set and the speed of the diesel engine have improved to some extent, but still cannot meet the specified requirements. Further inspection of the compression force inside the cylinder is needed.

Use a cylinder pressure gauge to check the compression situation inside each cylinder of the generator set. Through testing, it was found that the compression force inside each cylinder of the generator set varies greatly. This situation is generally caused by the lax valve closure of the generator set and the excessive gap between the inner wall of the cylinder sleeve and the piston. Remove the cylinder cover of the generator unit and inspect the sealing of the intake and exhaust valves. After removing the cylinder cover of the generator unit, it was found that the two cylinder gaskets were not assembled correctly, and there was a lot of carbon accumulation in the valve seats of the first and third cylinders, and the intake and exhaust valves were not tightly closed;

Remove the carbon deposit on the cylinder head of the generator set, grind the valve until it is sealed, and adjust the valve clearance of the generator set to the normal value after assembling the cylinder head. After starting the generator set, observe the speed, smoke exhaust and frequency of the generator set again, and find that all the above faults disappear.
