Abstract

PURPOSE:To improve the stability of the engine by arranging that the present calculated ignition timing and the previous ignition timing with each other and that the difference does not exceed a certain predetermined value. CONSTITUTION:The outputs of an angle detector 1 and a pressure detector are coupled to an ignition timing calculation unit 3, and an ignition system effects ignition in the individual cylinders in the engine in calculated ignition timings. In the ignition timing calculation unit 3, the previous ignition timing is memorized, and the ignition timing this time calculated from the engine operating conditions are compared are compared with each other. When the difference exceeds a predetermined value, the ignition this time is made at an instant obtained by adding a predetermined value to the predetermined value or subtracting it from the predetermined value, while when the difference is within the predetermined value the ignition is made on the basis of the result of calculation.
