Abstract: PROBLEM TO BE SOLVED: To optimize ignition timing control of each cylinder during idling driving.SOLUTION: A deviation between a target crank angle and peak timing of combustion pressure, detected based on an ion current, of each cylinder is computed, and feedback correction (advance correction or retard correction) for reducing the deviation is added to ignition timing of the cylinder in order to determine the ignition timing at the time of the next combustion in each cylinder.
