PURPOSE:To carry out ignition always at the most proper point by learning the correction value for the ignition timing when knocking can be avoided according to the acceleration state of an engine and executing ignition at the delayed angle in the acceleration state in which knocking was generated in the past. CONSTITUTION:The control value memorized by a means A is searched by a means D on the basis of the engine operation state detected by a means C. The correction value memorized by a means B is searched by a means E, on the basis of the engine acceleration state detected by the means C. The control value is corrected by the correction value by a means F, and the operation of an ignitor G is controlled on the basis of the correction. While, the existence of the generation of knocking due to ignition is detected by a means H. Therefore, when knocking is generated in the engine acceleration state, the data of the correction value which is memorized in the means B is rewritten to the delayed angle side by a means I. Therefore, the data of the correction value is renewed through learning, and ignition is carried out always at the most proper point. |
