ABSTRACT:
An engine control device for controlling the number of revolutions per minute of an engine to be at a prescribed target value in a precise manner during the idling operation thereof. A signal generator generates an output signal representative of the crank angle of the engine in synchrony with the rotation thereof. In one aspect, the number of revolutions per minute of the engine is successively calculated based on the signal generator output. A present average number of revolutions per minute of the engine is calculated and updated every ignition instant. A deviation of the present average number of rpm from the predetermined target value is calculated from the present average number of rpm. The ignition timing is determined based on the deviation thus calculated in such a manner as to maintain the number of engine rpm at the target value. In another aspect, when the number of engine rpm falls into a prescribed idling operation range such as when the engine is decelerated with a clutch disengaged, the operation of the controller for maintaining the number of rpm at the target value is delayed a predetermined time so that a sharp change or an excessive decrease below the target value in the number or rpm can be avoided.
