Abstract
PURPOSE: To perform an appropriate air-fuel ratio change-over control during the time of acceleration, a cruise, and deceleration of a vehicle by cnducting the air-fuel ratio change-over by using the throttle valve opening rate and an voltage signal.
CONSTITUTION: A signal on an intake air flow rate detected by a take air flow meter 7 is input to a combined circuit 9, which consists of an EGI control unit 3 and a composite circuit 8 constisting of circuits classified by the intake air flow rate, a solenoid driving circuit for the ignition timing control, and a solenoid driving circuit for an EGR control. From the combined circuit 9, driving electric power is output to a terminal 6' for an ignition timing control solenoid, a terminal 5' for an EGR control solenoid, and a fuel injection valve 4.
