Take a look at our full line of low price ATV Piston Rings and Pins from top manufacturers Centauro and J.E. Pistons. Piston Rings are open-ended rings that fit into a groove on the outer diameter of an ATV Piston in reciprocating engines such as combustion engine or steam engine.
Piston rings commonly used include the compression ring, wiper ring, and oil ring. A compression ring is the piston ring located in the ring groove closest to the piston head. The compression ring seals the combustion chamber from any leakage during the combustion process. When the air-fuel mixture is ignited, pressure from combustion gases is applied to the piston head, forcing the piston toward the crankshaft. The pressurized gases travel through the gap between the cylinder wall and the piston and into the piston ring groove. Combustion gas pressure forces the piston ring against the cylinder wall to form a seal. Pressure applied to the piston ring is approximately proportional to the combustion gas pressure.
