Abstract

PURPOSE: A sintered alloy piston ring which has eliminated the possibility for breakage during machining or mounting in ring grooves of pistons, deterioration in air tightness with the inside walls of cylinders owing to plastic deformation, and degradation in face pressure distribution and is expected to reduce reduction in tension and improve fatigue strength.
