A
piston ring is a split ring that fits into a groove on the outer
diameter of a piston in a reciprocating engine such as an internal
combustion engine or steam engine.
The three main functions of piston rings in reciprocating engines are :
>Sealing the combustion chamber so that there is no transfer of gases from the combustion chamber to the crank.
>Supporting heat transfer from the piston to the cylinder wall.
>Regulating engine oil consumption.
