Piston Ring is a metal ring inserted into the piston groove. There are two kinds of piston rings: compression ring and oil ring. The compression ring can be used to seal the combustible mixture gas in the combustion chamber. The oil ring is used to scrape excess oil from the cylinder.

Piston ring is a kind of metal elastic ring with large outward expansion deformation. It is assembled into the annular groove corresponding to the profile. Reciprocating and rotating piston rings rely on the pressure difference between the gas or liquid to form a seal between the outer circle of the ring and the cylinder and one side of the ring and the groove.

The piston ring is the core part of the fuel engine. It seals the fuel gas together with the cylinder, piston and cylinder wall. Commonly used automotive engines have two kinds of diesel and gasoline engine, due to its fuel performance is different, the use of piston rings are not the same, the early piston ring by casting, but with the progress of technology, steel high power piston ring was born, and with the continuous improvement of engine function, environmental requirements, a variety of advanced surface treatment applications, such as thermal spraying, electroplating, chrome plating, Gas nitriding, physical deposition, surface coating, zinc manganese phosphating treatment, so that the function of the piston ring is greatly improved
