Abstract

PURPOSE: To improve thermal efficiency of an engine utilizing heat of exhaust gas, by providing ceramic member around the peripheral wall of compression chamber and thereby raising the temperature of exhaust gas.
CONSTITUTION: Peripherally of the lower surface of cylinder head 1, a ring-like heat insulating ceramic member 7 is fitted in the manner not covering the holes of intake and exhaust valves 2 and ignition plug 6. This ceramic member 7 is made of ceramic material such as glass ceramics (crystallized glass), silicon nitride, silicon carbide or alumina, and in order to absorb thermal distortion, damper spacer 8 is interposed between the back surface of ceramic member 7 and cylinder head 1.
