    Abstract: PURPOSE: A piston top ring for an engine is provided to improve engine output by reducing amount of blowby gas and to reduce air pollution and waste of the oil by preventing oil from letting in a combustion chamber. CONSTITUTION: A head unit of a piston receives heat of high temperature the same as a cylinder forming a combustion chamber. The piston has a smaller diameter than a diameter of a skirt unit to form a clearance. The piston ring is installed on the head unit to prevent leakage of compressed gas through the clearance. Thereby, the piston ring maintains tightness of the combustion chamber against pressure of expansion gas. In addition, the piston ring prevents leakage of the expansion gas to a crankcase from the combustion chamber. The piston ring transfers heat into a wall of the cylinder while forming a film by scratching oil of the cylinder. Moreover, the piston ring is inserted to a groove by being formed as a ring composed of steel to prevent the oil from letting in the combustion chamber.
