What is a Piston Ring?
Piston ring is used to insert the piston groove inside the metal ring, piston ring is divided into two types: 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.
The piston ring is a kind of metal elastic ring with large outward expansion deformation, which is assembled in the profile and its corresponding annular groove. Reciprocating and rotating piston rings rely on the pressure difference of 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 ring groove.
Commonly used car engines have two kinds of diesel and gasoline engines, because of their different fuel performance, the use of piston rings are not the same.
Early piston rings were formed by casting, but with the progress of technology, high-power steel piston rings were born, and with the continuous improvement of engine functions and environmental requirements, a variety of advanced surface treatment applications, such as thermal spraying, electroplating, chromium plating, gas nitriding, physical deposition, surface coating, zinc-manganese phosphating treatment, etc., the function of the piston ring is greatly improved.
