When the energization cutoff timing is temporarily stored and the crank angle position determined by the reference signal of the corresponding cylinder inputted from the reference signal distribution means and the position signal inputted from the crank angle sensor coincides with the set energization start timing. The ignition signal output means starts energization to the temporary side of the corresponding ignition coil, and outputs an ignition signal that causes ignition to occur by cutting off the energization when the set energization cut-off timing coincides with the same. Ignition system for internal combustion engines.
