Piston and Piston Rings. A piston is a cylindrical engine component that slides back and forth in the cylinder bore by forces produced during the combustion process. The piston acts as a movable end of the combustion chamber. The stationary end of the combustion chamber is the cylinder head. Pistons are commonly made of a cast aluminum alloy ...

The three main functions of piston rings in reciprocating engines are: 1. Sealing the combustion/expansion chamber. 2. Supporting heat transfer from the piston to the cylinder wall. 3. Regulating engine oil consumption. During the compression and power strokes, the compression ring seals the combustion gases and prevents blow-by.
