Abstract
A transient correction of an ignition timing is precisely executed even in a transient state. The ignition timing at a stationary time is computed on the basis of an operating state detected by an operating state detecting means, and the ignition timing at the stationary time is corrected by a transient time ignition timing correcting means defined by a transfer function G(s).
