An engine piston is a cylindrical metal component that reciprocates (moves up and down) inside an engine cylinder to convert the explosive energy of burning fuel into mechanical motion. It acts as the movable end of the combustion chamber, with piston rings sealing the gap against the cylinder wall to prevent gas leakage. This force is transmitted via a connecting rod to the crankshaft, which ultimately rotates the engine's wheels.
