Abstract
PURPOSE:To improve the accuracy in controlling an air-fuel ratio by determining the quantity of fuel injection based on both the stroke of accelerator pedal footing and revolutions, and controlling a throttle valve by use of the correction of acceleration corresponding to an amount of air and the delay in fuel feed obtained on the basis of those such as the stroke of accelerator pedal footing, the change ratio thereof and revolutions. CONSTITUTION:Revolution signals N and water temperature signals Tw are inputted into a microprocessor 6 together with detected values from an air flow meter 2, an air-fuel ratio sensor 4, a crank angle sensor CS, an accelerator opening sensor 5 and the like so as to perform an operational control of the opening time of a fuel injection valve 7. The microprocessor 6 determines the quantity of fuel injection based on those such as the accelerator opening, revolutions and water temperature. And an acceleration correction factor and a load correction factor are obtained from the change rate of the accelerator and the stroke of accelerator pedal footing respectively so as to make the correction to an amount of air based on those such as these correction factors, a revolution correction factor and a water temperature correction factor for controlling the opening of a throttle valve 9 via a throttle actuator 8.
