Abstract

L'invention concerne une bougie d'allumage à effet de surface formée d'un corps isolant (12) et pourvue d'une électrode de masse (16), dans laquelle le corps isolant s'étend dans une direction privilégiée (D) et se termine par une face d'extrémité (13) sensiblement plane.Le corps isolant est traversé sur sa périphérie par au moins deux électrodes (11) alimentées en haute tension dont une extrémité en forme d'ergot (14) fait saillie de la face d'extrémité du corps isolant, chaque ergot s'étendant dans une direction prédéterminée. Pour chaque électrode haute tension (11), une contre-électrode (15) reliée à la masse est insérée dans le corps isolant, son extrémité étant localisée sensiblement à l'aplomb de l'ergot de l'électrode haute tension correspondante de manière à générer une amplification suffisante du champ électrique au niveau de l'extrémité de l'ergot pour faire jaillir une étincelle vers l'électrode de masse lors de l'application d'une haute tension à l'électrode haute tension.The invention relates to a surface effect spark plug formed of an insulating body (12) and provided with a ground electrode (16), in which the insulating body extends in a preferred direction (D) and ends with a substantially planar end face (13). The insulating body is crossed on its periphery by at least two electrodes (11) supplied with high voltage, one end of which in the form of a pin (14) protrudes from the face end of the insulating body, each lug extending in a predetermined direction. For each high voltage electrode (11), a counter-electrode (15) connected to ground is inserted into the insulating body, its end being located substantially in line with the lug of the corresponding high voltage electrode so as to generating sufficient amplification of the electric field at the end of the lug to cause a spark to fly towards the ground electrode upon application of a high voltage to the high voltage electrode.
