Diesel generator set piston ring is generally divided into gas ring and oil ring.The function of the oil ring of diesel generator set is to prevent the excess oil on the cylinder surface from running into the combustion chamber, and to distribute the oil evenly on the cylinder wall to improve the lubrication conditions of the piston group.

 

The oil ring of diesel generator is located below the gas ring, and its working temperature and gas pressure are relatively low.Therefore, on the one hand, the oil ring of diesel generator set has a large elastic force, and at the same time, the contact surface between the ring and the cylinder wall is reduced as much as possible, so as to enhance the contact pressure per unit area.
