Abstract
A piston ring having a ring-shaped body with at least one internal wall surface configured to bear against the piston, an exterior wall surface, and at least a top wall surface extending from the exterior wall surface to the at least one internal wall surface and capable of intersecting a top surface of the piston to form an extended top surface of the piston when mounted on the piston. The top wall surface of the ring cooperates with the piston top surface to form a reservoir that collects liquid scraped off the cylinder wall, thereby reducing or eliminating blow-by of contaminants to the crankcase.
