INTERNAL COMBUSTION ENGINE, METHOD FOR NEUTRALIZING THE INCREASE IN THE OCTANE REQUIREMENT IN THIS ENGINE, SYNTACTIC FOAM FOR COATING THE SURFACES OF A COMBUSTION CHAMBER OF SAID ENGINE, AND PISTON AND VALVE FOR THE ENGINE

摘要

THE INVENTION CONCERNS THE APPLICATION OF A COATING ON CERTAIN SURFACES OF AN INTERNAL COMBUSTION ENGINE. /P P THIS COATING IS IN PARTICULAR APPLIED ON CERTAIN SURFACES OF THE COMBUSTION CHAMBER 1, OF THE INTAKE MANIFOLD 2 AND OF THE INTAKE VALVE 4 OF AN INTERNAL COMBUSTION ENGINE. THE COATING CONSISTS OF A RESINOUS FOAM WHOSE THERMAL CONDUCTANCE AND THERMAL PENETRATION ALLOW THE TEMPERATURE OF THE COATED SURFACES TO EXCEED, DURING THE COMBUSTION PROCESS, THE TEMPERATURE OF THE FORMATION OF DEPOTAMFASENT BY CHALLENGE, WITHOUT EXCESSIVE TO RAISE THE TEMPERATURE OF THE AIR AND FUEL INTAKE CHARGE DURING THE ENGINE CYCLE INTAKE AND COMPRESSION TIMES. /P P FIELD OF APPLICATION: INTERNAL COMBUSTION ENGINES.
