1. The fuel supply time is incorrect, and the fuel supply advance angle may be large or small. If the high-pressure oil pump installation gasket has been tampered with in the past, it is recommended to restore it to its original factory condition. Because the fuel supply advance angle has been adjusted to the optimal state when leaving the factory.
2. Excessive clearance between the piston rings leads to air leakage during the compression stroke, causing the cylinder air compression temperature to fail to reach the state of fuel self ignition.
3. The plunger pair of the high-pressure oil pump is severely worn, and the fuel supply pressure is too low, resulting in poor atomization quality of the fuel injector and difficult combustion. Suggest replacing the plunger pair.
4. The aging of the fuel injector, incomplete fuel cut-off, and dripping of oil result in poor atomization quality. Suggest replacing the fuel injector.
5. The air filter is severely blocked and the intake is insufficient. It is recommended to clean it.
