Abstract (en)
[origin: WO2006054009A1] The invention concerns a so-called radiofrequency plasma spark plug (1) designed to equip a combustion chamber (2) comprising: an annular shell (3) with a main axis D; a central electrode (7) made of a second conductive material, extending along the main axis D and including an inner portion (8) arranged inside said annular shell (3) and an outer portion (9) arranged outside said annular shell (3); an annular electrically insulating part (10) extending at least about the inner portion (8) of the central electrode (7) so as to be interposed between the shell (3) and the electrode (7), said insulating part (10) only covering part of the outer portion (9) of the central electrode (7). The insulating part (10) having an annular flange (11) concealing the entire circular terminal surface (6) of the shell relative to the uncovered part (16) of the electrode (7).
