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.

The gap in the piston ring compresses to a few thousandths of an inch when inside the cylinder bore. Carburetor Seat are a major factor in identifying if an engine is two stroke or four stroke. Three piston rings suggest that it is a four stroke engine while two piston rings suggest that it is a two stroke engine.
