ABSTRACT:
A plasma ignition system for an internal combustion engine which can prevent irregular ignition when the insulation between the electrodes of the spark plug deteriorates due to carbon on the electrodes, and further can prevent electrical noise from being emitted. The system according to the present invention comprises a plasma ignition energy storing condenser, a plurality of switching units, and boosting transformers one each for each of the engine cylinders. In this system, a high tension is generated at the secondary coil of the boosting transformer to generate a spark between the electrodes of the plug and subsequently a large current is passed through the electrodes by the remaining energy stored in the condenser.
