An ignition control system for an internal combustion engine has means for determining the maximum energizing time of an ignition coil from a signal synchronized with the ignition timing of the engine and controlling the period that the energizing current reaches a predetermined value to a predetermined value, thereby determining the maximum energizing time of the ignition coil from the signal synchronized with the ignition timing of the engine, detecting the energizing current of the ignition coil, and variably setting the maximum closed-circuit rate of energizing the ignition coil according to the operating state of the engine and a battery voltage.
