Fuel and outside air are sucked into the exhaust manifold 18, and exhaust gas is exhausted from the exhaust manifold 18 to the exhaust pipe 19. As the suction negative pressure acts on the heated air injection flange 7, the outside air flowing from the air cleaner 21 through the air regulator 24 and through the air heater 17 is heated to a high temperature by heat conduction from the exhaust gas. , the heated secondary air is injected obliquely downward from the primary hole 2 of the heated air injection 7 lange 7 and the injection holes 5, 51 on the inner surface of the 21 21 while swirling. Therefore, the mixture is 1
: The mixture is diluted to a mixture ratio of 15 or more, raised to high temperature, completely gasified, and completely combusted in the cylinder 12. The CO acid component HC in the exhaust gas is completely combusted in the cylinder 12. It is possible to reduce the amount of components and improve fuel efficiency. In particular, in the present invention, the injection hole 5
．． 51 is spirally inclined obliquely downward, and the cylindrical body 10
．． 10' is provided on the lower surface of the injection flange 7, a large amount of heated secondary air is injected in a whirlpool due to the venturi action of the shank tube 11, and mixes well with the air-fuel mixture to form gasoline. The fine particle component is further made into ultrafine particles.
