PURPOSE:To stabilize the engine rotation quickly under idling by providing an ignition timing operating means for leading the ignition timing correctively on the basis of a correction factor based on the fluctuation of rotation and the engine condition. CONSTITUTION:Rotary fluctuation operating means 111 will operate the rotary fluctuation which is the difference between average rotation and instantaneous rotation of engine. Correction factor for correcting the rotary fluctuation with correspondence to the engine rotation is operated through correction factor operating means 113. On the basis of the rotary fluctuation and the correction factor, ignition timing control means 114 will operate the optimal ignition timing under idling of engine thus to suppress rotary fluctuation. Consequently, engine rotation under idling can be stabilized quickly. |
