PURPOSE:To control the amount of atomization in a fuel-atomizing device correctly by providing a blower of a supercharger in the downstream of the fuel- atomizing device. CONSTITUTION:An air-fuel mixture supply port 22 is provided in the downstream of an air-intake port 20 of a mixing chamber 19 to be opened to a Venturi tube part 21 provided on a suction passage 4, and the mixture of the auxiliary fuel and sucked air in the mixing chamber 19 is conducted to a suction passage 4 by the negative pressure generated by the Venturi tube part 21. A supercharger 10 is provided in the downstream of the air-fuel mixture supply port 22 of a fuel-atomizing device 9 between a suction passage 4 and an exhaust passage 6. Since a blower 25 of the supercharger 10 is equipped in the downstream of the fuel-atomizing device 9, the mixing chamber 19 and an oil face 26 in a casing 14 are free from the charging pressure of the blower 25, and the air raised in temperature cannot be introduced into the mixing chamber 19. This construction permits to control the supply amount of auxiliary fuel correctly. |
