Abstract

L'invention porte sur une bougie d'allumage pour moteurs à combustion interne, qui contient un corps massif (2) qui est électroconducteur et thermoconducteur; dans sa cavité intérieure, un isolant étanche aux gaz, en céramique (1) est logé avec une électrode centrale (3) dont l'extrémité saillante est située à l'intérieur d'un cylindre (17) de la bougie d'allumage. La partie inférieure du corps (2) de la bougie d'allumage est un tronc de cône et les trous de passage latéraux (5) sont conçus dans un schéma radial autour de la bougie d'allumage sur la gaine conique, tandis que les trous de passage (5) sont inclinés vers l'axe vertical de la bougie d'allumage à un angle de 45° à 90°. Au moins deux trous de passage latéraux (5) sont conçus dans un schéma radial autour du périmètre de la gaine conique de la bougie d'allumage. En supplément, la bougie d'allumage peut avoir un trou de passage vertical unique (13) et (16) dans l'électrode de masse (10) de la bougie d'allumage, qui est disposé coaxialement à l'électrode (3) de la bougie d'allumage et qui est intégré à une partie inférieure (11) de la bougie d'allumage. L'électrode de masse (10) est homogène avec un corps (2) de la bougie d'allumage, ou est un élément séparé (15) combiné sur une base permanente au corps (2) de la bougie d'allumage. Selon cette variante, la bougie d'allumage à passage a été conçue de telle sorte que le déclenchement de l'allumage à l'intérieur du cylindre (17) de la bougie d'allumage se produit dans la partie centrale du cylindre (17) de la bougie d'allumage, tandis que les trous de passage (5) sont positionnés de telle sorte que la flamme qui se propage à l'intérieur du cylindre (17) de la bougie d'allumage recouvre relativement une distance aussi petite que possible après le déclenchement de l'allumage vers les trous de passage (5). En supplément, pour raccourcir le temps que la flamme prend pour atteindre les trous de passage (5) et donc pour accélérer le moment de déclenchement de l'éjection des courants chauds dans la chambre de combustion du moteur, une ailette (12) est utilisée à l'intérieur de la bougie d'allumage, laquelle peut se présenter en deux variantes, à savoir sous la forme d'une seule pièce du corps (2) homogène avec le corps (2), ou sous la forme d'une bague (14) noyée à froid dans le corps (2), ou encore assemblée par pression à l'intérieur du corps (2).
