PURPOSE:To improve engine startability ever so better, by installing a heater, capable of heating air, in a position short of a suction valve inside a suction pipe, while installing another heater, capable of heating ethanol, inside a fuel injection valve or the suction pipe. CONSTITUTION:An electric heater 9 heating air A is installed in a position short of a suction valve 1 inside a suction pipe 10. In addition, a fuel injection valve 4 spraying ethanol to the inside of the suction pipe 10 is installed in the suction pipe 10. The fuel injection valve 4 is also provided with a heater 8 heating the ethanol. At the time of starting, the air A inside the suction pipe 10 is heated by the heater 9, and the ethanol heated further by the heater 8 is sprayed to the inside of the suction pipe 10 from the fuel injection valve 4. Thus, favorable starting is performable. |
