OSTI ID:6491372
An improved two-cycle engine in which the inner wall of the head of the combustion cylinder facing the combustion chamber is formed of a heat-insulating ceramic element which surrounds the tip of a mounting portion of the spark plug of the cylinder. The tip of the spark plug should be threadless in the area surrounded by the ceramic element. The ceramic element is preferably a sintered product made of silicon nitride, zirconia, sialon, alumina or silicon carbide.
