Abstract

A poppet valve that comprises a valve head and a valve stem is used in an internal combustion engine. The valve head is covered with a heat-insulating film except a valve face. The film is made of ceramics. Furthermore, a heat-shielding plate is fixed over a front face of the valve head to form a heat-insulating space between the plate and the front face thereby decreasing operational temperature of the valve.
