Zusammenfassung:	PURPOSE:To prevent erroneous operation due to noise which takes place upon driving of actuators, by blocking the delivering of actuator drive signals from an electronic control device during operation of detectors for detecting the running parameters of the engine. CONSTITUTION:An electronic control device 33 computes various control signals in accordance with engine running parameters detected by an air-flow meter 1 and sensors 21, 23, 24, 25, 27 for detecting the temperature of intake-air, the temperature of cooling water, knocking, the air-fuel ratio, and the rotational speed, respectively. Further, the thus obtained control signals are used for controlling actuators such as, for example, a step motor 13 for a flow control valve, a fuel injection valve 15, an ignition device 15, etc. In this arrangement, upon rotational speed interuption process of a running parameter detecting means such as, for example, the rotational speed sensor 27, an actuator such as, for example, the step motor 13, is deiven during the period of the rotational speed interruption mask, but the operation of the actuator is inhibited other than the period.
