Extended data:

Engine:

The displacement of Cummins engine is 1.4~9 1 liter, and the power range covers 3 1~3500 horsepower. Widely used in road vehicles such as heavy trucks, medium-sized trucks, buses, recreational vehicles, light commercial vehicles, pickup trucks, and off-road equipment such as construction machinery, mining equipment, agricultural machinery, ships and railways.

The reliability, durability and fuel economy of Cummins engine are few in the industry, and it has always been in the leading position in the fierce competition to meet the increasingly stringent automobile emissions, off-highway motor equipment emissions and ship engine emissions.

If the negative hole in the middle of the small piston is blocked, the pressure oil in the C cavity can not be obtained, and the pressure in the C cavity is far lower than the system pressure, so the small piston is always in the left shift position. No matter whether the system pressure is high or low, it is still in an overflow state. So once the small damping hole is blocked, the impact will be great.
