The cause of the fuel oil into the oil pan

1:PT pump shaft oil seal is damaged, permeate to diesel oil seal after timing gear box into the oil pan

2:PT fuel pump electromagnetic valve sealing ring is damaged, diesel by cutting off valve into the injector, the combustion chamber the oil sump

3:When the injector hole is too large, or damaged, can lead fuel oil into the oil pan

4:When Fuel injector o-ring damaged, will lead to fuel oil into the oil pan.

5: When Fuel injector working time is not correct, cause incomplete combustion, redundant diesel oil into the oil pan

6:Piston, piston ring and cylinder liner damaged, can lead fuel oil into the oil pan

7: some cylinder pressure too low to work can lead fuel oil into the oil pan.

8:Air filter blockage, or damage of the turbocharger etc, make the diesel generator set intake inadequate, incomplete combustion, can lead fuel oil into oil pan.
