ABSTRACT:
An engine control apparatus for changing the air/fuel ratio of an air-fuel mixture supplied to the engine to a richer value each time the exhaust gas temperature exceeds a target value while the engine is operating at high-speed and high-load conditions. During the air/fuel ratio control, the timing of the sparks supplied to the engine is changed, in relation to the changed air/fuel ratio, to retain the engine output torque at a uniform value.
