PURPOSE:To rapidly and surely heat and evaporate fuel by forming a heater face which electrically generates heat on an intake downstream side face of a throttle valve, and arranging a fuel injector on the intake downstream side therefrom, and pointing the fuel injection direction to the heater face. CONSTITUTION:An intake port 3 is formed in the combustion chamber 2 of an engine 1, and an intake manifold 6 is mounted on its mounting part 5. A throttle valve 15 is rotatably arranged in the throttle body part of the intake manifold 6 via a throttle shaft 16. In this case, a valve body part is mode of a heat insulation material in the throttle body 15, and the heating face where a flat face heater is buried is formed on the downstream face side. A fuel injector 9 is arranged on the mounting part 12 formed on the downstream side of the throttle body part. The fuel injection direction of the fuel injector 9 is pointed to the heating face of the throttle valve 15. Consequently, fuel is rapidly and surely heated and evaporated. |
