Abstract
A substantially circumferential annular member is installed in the region defined by the rear face of a piston compression ring and the upper and lower walls and the bottom of the compression ring groove. The annular member moves within said room by the action of inertia forces arising out of the piston reciprocating motion, thereby preventing the build-up of carbon particles in the piston compression ring groove.
