ISBE CUMMINS piston ring 102mm 4089258
Piston rings include gas rings and oil rings. The role of the gas ring is to ensure the seal between the piston and the cylinder. Prevent the cylinder in the high temperature, high pressure gas leakage into the crankcase, but also the top of the piston to conduct most of the heat to the cylinder wall, and then by the cooling water or air away.
Oil ring is used to scrape the excess oil on the cylinder wall, and in the cylinder wall coated with a uniform oil film, which can prevent oil fleeing into the cylinder combustion, and can reduce the piston, piston ring and cylinder wear, reduce friction resistance.
Piston ring marking GB/T 1149.1-94 stipulates: All piston rings requiring installation direction should be marked on the upper side, that is, the side close to the combustion chamber. The rings marked on the upper side include: tapered rings, internal chamfering, external cutting table rings, nose rings, wedge-shaped rings and oil rings requiring installation direction, the rings are marked on the upper side.

The role of piston rings:
1, sealing role: piston rings can maintain the seal between the piston and the cylinder wall, control leakage to a minimum, by the gas ring, can prevent air leakage caused by the cylinder and piston or cylinder and ring between the bite, but also to prevent the deterioration of lubricating oil caused by the failure;
2, thermal conductivity: piston rings can be high heat transfer generated by combustion dispersed to the cylinder wall.
