Abstract

A substantially circumferential annular member 2 is installed in the region defined by the rear face 10 of a piston compression ring and the upper and lower walls 3, 4 and the bottom 5 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. The annular member has an axial dimension greater than clearances f1, f2 and may be sinuous. <IMAGE>
