Abstract
PURPOSE:To prevent slippage in an air-fuel ratio due to variations and secular change of an intake air quantity detecting device by storing a compensating quantity by air-fuel feedback compensation, and finding the compensating quantity of an output characteristic value of the intake air quantity detecting device from the stored value at an equal intake air quantity area. CONSTITUTION:Each detected value of an air flow sensor 1, a crank angle sensor 2, an air-fuel ratio sensor 3, a water temperature sensor 4, a throttle valve opening sensor 5, etc., is inputted into a control unit 10, and a fundamental fuel injection quantity calculated by intake air quantity and engine speed is compensated by a feedback compensation factor or the like on the basis of the detected value of the air-fuel ratio sensor 3. On the basis of this feedback compensation factor, a learning vale at every learning area determined by the fundamental fuel injection quantity and the engine speed is renewed. A compensation quantity of the output characteristic value of the air flow sensor 1 is operated and stored from a value at an equal intake air quantity area of this learning value, and variations in the output characteristic of the air flow meter 1 is compensated.
