An electric or electronic system for igniting an internal combustion engine comprising generating electric pulses from a pulse generator at such a desired pulse rate as capable of producing a desired number of electric discharges per one explosion step in each of engine cylinders at the maximum rotational number of an engine crank shaft, stepping-up the voltage of the generated pulses to such a level as enabling electric discharges in a distributor and ignition plugs of the engine cylinders, distributing the thus stepped-up pulses from a feed arm to each of stationary electrodes of the distributor corresponding by the number to that of the cylinders and producing pulse discharges at the desired pulse rate from the ignition plug in each of the cylinders connected to each of the stationary electrodes at the optimum explosion timing to thereby ignite evaporated fuels in the cylinders. An advance control means for the angle of discharge to the stationary electrode adapted to radially displace the feed arm centrifugally due to the rotation of the crank shaft may, desirably, be incorporated to the engine ignition system.
