ABSTRACT:
An actual ignition timing detecting device for use with a simultaneous ignition engine in which two cylinders are actually ignited in an alternate manner by simultaneously applying an ignition pulses generated in inverse polarities between the two terminals of an ignition coil. The actual ignition timing of the two cylinders can be detected from the rise and fall of a pulse signal, which rises at the misfire timing and falls at the actual ignition timing, by detecting the ignition pulses of one of the cylinders and by forming that pulse signal at all times in accordance with the difference in waveform between the actual ignition and misfire pulses of the ignition pulses detected.
