Abstract

PURPOSE:To make a control adapted to the operating condition of the engine by a method wherein a condition in which an exhaust gas recirculating valve is left closed due to the abnormality of an exhaust gas recirculating system is detected and an air-fuel ratio as well as an ignition timing are corrected to a predetermined value. CONSTITUTION:One end of a vacuum path 7, communicated with a vacuum chamber 5d moving the valve body 5a of the exhaust gas recirculating valve 5 interposed on the recirculating path 4 of the exhaust gas by the vacuum thereof, is opened in a path 2 and the other end thereof is opened to atmosphere through vacuum solenoid valve 8 and an atmosphere solenoid valve 9 while a circuit 10, controlling the valves 8, 9, controls a fuel injection device 11 and an ignition device 13 through a correcting system 12. When a difference between target moving amount of the valve body 5a and an actual moving amount thereof is not becoming zero after a predetermined period of time is elapsed and the condition in which the valve body 5a is left closed is detected, an abnormality detecting system 17 outputs a signal to the system 12 to correct the signal from the circuit 10 to the devices 11, 13 and the air-fuel ratio is made lean or the angle of ignition timing is delayed, for example.
