ABSTRACT:
In controlling ignition timing in accordance with a deviation between a target ignition timing determined on the basis of at least an engine load and an engine speed and an actual ignition timing detected by use of an ignition timing sensor, when non-perfect explosion operating conditions, wherein an ignition signal is difficult to detect, or operating conditions in which the ignition signal is instable are present, an open loop control on the basis of the engine load and the engine speed is effected. Feedback control is effected when the ignition signal is detected with neither non-perfect explosion operating conditions nor instable ignition signal operating conditions being present. When the ignition signal is not detected, the aforesaid open loop control is effected and a trouble in the ignition timing sensor is detected.
