Abstract

PURPOSE:To permit engine operation in the vicinity of MBT (Minimum advance for best torque) in idling by detecting ignition and miss-fire of the engine from the crank angle position where the number of revolution of engine becomes max. and advancing the ignition timing when ignition is realized and delaying the ignition timing when miss-fire is generated. CONSTITUTION:A throttle-valve switch is read-out in step 51, and steps 53-57 are executed only in idling. The crank angle RPMDEG with which the acceleration speed in engine revolution in the preceding ignition cycle becomes max. is compared with, for example, 70 deg. (step 53). When RPMDEG is larger than 70 deg., ignition is judged, and the ignition timing is advanced. When RPMDEG is equal to or less than 70 deg. miss-fire is judged, and the ignition timing is delayed. Thus, the ignition timing can be set always in the vicinity of MBT in idling.
