Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for electrically powering an ignition spark plug of a combustion engine to an electric voltage adapted to ensure generation of a branched ignition spark, the method comprising: increasing the electric voltage for powering the spark plug from a zero voltage to a first voltage stage created at an electric voltage value just necessary for formation, at a free end of an electrode of the spark plug, of first electric filaments originating from the…
