Abstract

Dispositif allumage pour moteur à combustion interne comprenant une chambre de combustion principale (13) et une préchambre de combustion (14) comprenant des moyens d’allumage (15), ladite préchambre étant relié à ladite chambre principale par une pluralité d’orifices de passage (133) destinés à l’alimentation de ladite préchambre en mélange combustible sous l’effet de la compression dudit mélange dans ladite chambre principale et, après allumage dudit mélange, à l’éjection des gaz brûlés dans une zone supérieure (130) de ladite chambre principale, sous l’effet de la montée en pression dans la préchambre, ladite zone supérieure comportant une enceinte intermédiaire (131) comprenant une partie supérieure close (132) faisant saillie dans ladite préchambre et reliée à celle-ci par ladite pluralité d’orifices de passage, chacun d’eux débouchant dans ladite enceinte intermédiaire d’une manière sensiblement tangentielle par rapport à une paroi axiale (135) de ladite enceinte, et une partie inférieure ouverte (134) débouchant dans ladite chambre principale.
