Abstract: An exhaust gas suppressor which suppresses the generation of harmful gases contained in exhaust gases from internal combustion engines, wherein secondary air is efficiently heated to high temperature by a double-tubed heater installed downstream of the exhaust manifold of the internal combustion engine so as to connect to the internal combustion engine and is added to a mixture of primary air and fuel present in the suction manifold, the mixture being then fed to an eddy generating device, which generates eddies in the mixture for the complete gasification.

Abstract: An exhaust gas suppressor which suppresses the generation of harmful gases contained in exhaust gases from internal combustion engines, wherein secondary air is efficiently heated to high temperature by a coiled heater tube installed in the exhaust manifold of the internal combustion engine and is added to a mixture of primary air and fuel present in the suction manifold, the mixture being then fed to an eddy generating device which generates eddies in the mixture for complete gasification.
