QSL9 Cummins Engine Parts Piston Ring 4089644 For Sany 150T Crawler Crane
Piston Ring 4089644 is fitting on USA Cummins QSL9 Diesel Engine . The Cummins engine model is QSL ISL Series. Piston rings include air rings and oil rings.The air ring ACTS as a seal between the piston and the cylinder.Prevent large leakage of high temperature and high pressure gas in the cylinder into the crankcase, and conduct most of the heat from the top of the piston to the cylinder wall, which is carried away by cooling water or air. The oil ring is used to scrape the excess oil off the cylinder wall and apply a uniform oil film on the cylinder wall, which can not only prevent the oil from running into the cylinder, but also reduce the wear of piston, piston ring and cylinder, and reduce the friction resistance.
The high heat from the combustion is transmitted through the piston rings to the cylinder walls, thereby cooling the piston.The heat emitted through the piston ring to the cylinder wall can generally reach 30 ~ 40% of the heat absorbed by the top of the piston.
Since the piston is slightly smaller than the inner diameter of the cylinder, if there is no piston ring, the piston is unstable in the cylinder and cannot move freely.At the same time, the ring also prevents the piston from directly contacting the cylinder, which supports it.Therefore, the piston ring moves up and down in the cylinder, and its sliding surface is borne by the ring.

The first function of the piston ring is to maintain a seal between the piston and the cylinder wall, controlling the leakage to a minimum.This role is mainly assumed by the gas ring, that is, under any operating conditions of the engine, its compressed air and gas leakage should be controlled to the minimum, in order to improve thermal efficiency;Prevent air leakage caused by the cylinder and the piston or between the cylinder and the ring bite;Prevent the deterioration of lubricating oil caused by the failure.

The second function of the piston ring is to properly scrape the grease off the cylinder wall and maintain normal fuel consumption.When the supply of lubricating oil is too much will be sucked into the combustion chamber, so that fuel consumption increases, and because of the combustion of carbon deposition, the engine performance is very bad.
