Abstract

PURPOSE:To improve the efficiency of an engine by maintaining the ignition timing continuously immediately before the occurrence of knocking. CONSTITUTION:The engine knocking is detected by a knock detector 30 and provided through an I/O interface 20 to CPU 12. CPU 12 produces an interruption signal for control/interruption processing in accordance with the output pulse from said detector 30. Igition timing correction control will start in correspondence with said interruption signal. ROM 14 contains control program such as ignition timing control program and fixed data. Ignition signal after arithmetic operation is provided to a ignition coil driving circuit 60.
