PURPOSE:To prevent a blow back in the vicinity of a throttle valve full opening and the displacement of air fuel ratio due to a change of charging efficiency, by providing a limit value in accordance with operation parameters in a fuel supply amount calculated on the basis of detection signals of an intake air amount sensor and a crank angle sensor. CONSTITUTION:A control unit 30 calculates the basic fuel supply amount on the basis of detection values from an intake air amount sensor 13, serving for a Karman vortex street flow meter, and a crank angle sensor 17, performing various corrections on the basis of detection values of water temperature sensor 18, intake air temperature sensor 19, etc. The control unit 30 obtains a predetermined correction coefficient on the basis of engine speed, water temperature, intake air temperature, calculating the limit value of a fuel supply amount on the basis of this obtained correction coefficient.
