Abstract

PURPOSE:To alleviate shocks in time of reacceleration, to remove occurrence of abnormal combustion and get rid of the shortage of accelerating feeling by a method wherein among several kinds of ignition timing values calculated on the basis of several kinds of different conditions, the most advanced ignition value is used as the ignition timing. CONSTITUTION:A microcomputer 5 inputs signals from an angle sensor 1, a load sensor 2, a throttle switch 3 and a fuel cut-off detector 4, calculates ignition signals, controls the operation of a transistor 12 in an ignition device 11 to come into igniting operation. When the fuel transfers from a cut-off state to an acceleration state and the engine rotates for an intended time and at an intended number of rotation, among the 1st intended value (a positive number of one or less) multiplied by an optimum ignition timing, the value subtracting the 2nd intended value from the optimum ignition timing and the given 3rd intended value, the most advanced value is outputted as the ignition timing.
