Abstract:
A method for controlling the power supply of a radiofrequency spark plug in an internal combustion engine up to an electric voltage sufficient for generating a highly branched spark. To this end, the electric voltage for powering the spark plug is increased step by step up to an adequate voltage adapted for ignition.
