Abstract
PURPOSE:To improve the accuracy of a control apparatus in the caption by separating and studying intake air quantity and the characteristic value of a fuel supply means after such processes that the intake air quantity and the characteristic value of the fuel supply means are calculated and corrected from air-fuel ratio feedback correction quantity and invalid injection time is corrected from the value of the low load area after correction. CONSTITUTION:Each detected value of an intake air quantity sensor 1, a crank angle sensor 2, an air-fuel ratio sensor 3, a water temperature sensor 4, a throttle valve open degree sensor 5, a knock sensor 6 and a vehicle speed sensor 8 and the like is inputted into a control unit 10. The control unit 10 calculates the basic fuel injection quantity from the intake air quantity and the rotational speed, and this quantity corrected with the air-fuel ratio feedback correction quantity on the basis of the air-fuel ratio sensor 3, the correction quantities of the characteristic values of the intake air quantity sensor 1 and a fuel injection valve 11 calculated on the basis of the air-fuel feedback correction quantity and an invalid injection time calculated from the air-fuel ratio feedback quantity corrected by these characteristics values.
