Piston ring is a kind of metal ring used to embed into the groove of piston. There are two kinds of piston rings: compression ring and oil ring. The compression ring can be used to seal the combustible gas mixture in the combustion chamber; The oil ring is used to scrape the excess oil from the cylinder. Piston ring is a kind of metal elastic ring with large outward expansion deformation, which is assembled into the profile and its corresponding annular groove. Reciprocating and rotating piston rings, depending on the pressure difference of gas or liquid, form a seal between the outer circle of the ring and the cylinder, and between the ring and one side of the ring groove.

 

Piston rings form a seal between the piston and cylinder wall, which prevents pressurized combustion gases from entering the oil sump. They also regulate oil consumption by preventing excessive oil from entering the combustion chamber and burning.Properly functioning rings are vital to maximum engine power and efficiency.

Piston Ring is a metal Ring used to insert the inner Piston groove, Piston Ring is divided into two types: compression Ring and oil Ring.
 1 Compression Ring can be used to seal the combustion chamber combustible mixture of gas.
 2 The oil ring is used to scrape excess oil from the cylinder , Piston ring role includes sealing, oil regulation (oil control), heat conduction (heat transfer), guide (support) four roles.
