ABSTRACT:
An ignition control device for an internal combustion engine includes a digital control circuit which functions to reduce gradually a current flowing through a primary side of an ignition coil when a current supply to the primary side of the ignition coil continues for a time longer than a normal current supply period, to thereby prevent undesired spark discharge from occurring in an ignition plug.
