ABSTRACT:
An ignition detecting device for use in an internal combustion engine. An ignition surge current detector detects an ignition surge current due to capacitive discharge of the ignition coil. A comparator compares an output voltage detected by the ignition surge current detector with a predetermined reference voltage to detect accurately occurrence or non-occurrence of ignition spark.
