    • H01T13/52—Sparking plugs characterised by a discharge along a surface

Definitions

  • the formation of the surface discharge is promoted with increasing dielectric constant of the insulating body material
  • the formation of a surface charge on the surface of the insulating body is promoted by the lower part of the insulating body on the combustion chamber side, which leads to a particularly low ignition voltage.
  • the insulating body 10 is cross-divided in its end section on the combustion chamber side and therefore has an upper part 23 on the connection side and a lower part 24 on the combustion chamber side.
  • the upper part 23 consists of aluminum oxide (Al 2-, 03-,) with a dielectric constant £ .r

Abstract

Dans une bougie d'allumage à étincelle glissante, afin d'allonger le chemin de glissement de l'étincelle glissante avec une tension donnée d'allumage, la surface supérieure (22) du corps isolant (10) tournée vers la chambre de combustion est formée de telle sorte qu'elle soit traversée par une pluralité de lignes de champ (30) faisant partie d'un champ électrique généré entre l'électrode centrale (21) dans le corps isolant (10) et l'électrode annulaire de masse (16) montée sur le bâti métallique (11) et qui entoure l'électrode centrale (21). Une partie de l'électrode (16 resp. 21) qui représente la cathode (-) est agencée à une certaine distance derrière la surface (22), vue dans le sens d'écoulement des lignes de champ, en formant un angle avec celle-ci.
