A control unit has a fuel supply controller and a throttle valve opening degree controller. The fuel supply amount controller estimates and calculates the amount of fuel being supplied in cylinders with a real time. The throttle valve opening degree controller calculates a necessary opening degree so as to give a predetermined air-fuel ratio in accordance with a result value by the fuel supply amount controller. The fuel supply amount controller has a processing in which a fuel supply amount is corrected in accordance with an increase or decrease rate of an amount of fuel being adhered to an inner wall surface of an intake pipe. The throttle valve opening degree is controlled in accordance with a value obtained from the throttle valve opening degree controller as a control target value. A time lag in a follow-up for fuel is anticipated in advance, a desirable target air-fuel ratio is maintained correctly and easily.
