Abstract (en)
[origin: EP0384436A2] An ignition detecting device for use in an ignition apparatus of an internal combustion engine comprises ignition surge current detector means (10a) for detecting an ignition surge current generated in a primary circuit of an ignition coil (3) due to capacitive discharge of the ignition coil (3), and comparator means (10b) for comparing an output voltage of the ignition surge current detector means (10a) with a predetermined reference voltage (Vref) to detect the generation of the ignition surge current in excess of a predetermined value, thereby making it possible to detect accurately occurrence or nonoccurrence of ignition spark.
