ABSTRACT:
The ignition timing is controlled in that a change in engine speed is detected from a differentiated value dN/dt, and when dN/dt is larger than a predetermined value and when a value of dN/dt is positive, the ignition timing is retarded by a predetermined value from a fundamental ignition timing, and further, when dN/dt is larger than the predetermined value and when the value of dN/dt is negative, the ignition timing is advanced by the predetermined value from the fundamental ignition timing.
