Abstract (en)

[origin: WO2009147335A2] The invention relates to a method for controlling the power supply of a radiofrequency spark plug (1) in an internal combustion engine up to an electric voltage sufficient for generating a highly branched spark (130). To this end, the electric voltage for powering the spark plug is increased step by step up to an adequate voltage adapted for ignition.
