ABSTRACT:
An induction discharge system ignition device for an internal combustion engine includes a power switching device for producing a voltage to be applied to the primary winding of an induction coil. The secondary of the induction coil is connected to apply a high-tension voltage to a spark plug. The power switching device and the coil are particularly arranged to produce a voltage of at least 6.0 kV across the electrodes of the spark plug when the spark plug has a leakage of 100 k.OMEGA.. The turns ratio of the coil is, preferably, 70 or less.
