Abstract

La présente invention concerne une buse d'injection à gicleurs multiples pour les moteurs à combustion interne à compression d'air, et plus particulièrement pour les moteurs comportant une chambre de combustion à symétrie de rotation, aménagée dans le fond d'un piston 2. Cette buse d'injection 4, décentrée par rapport à l'axe de symétrie du piston, comporte plusieurs gicleurs 6 ayant des diamètres D, D' et des longueurs L différents, de telle manière que chaque jet de carburant 7a, 7b, 7c et 7d, qui a une longueur différente jusqu'au point d'impact sur la paroi 8 de la chambre de combustion 3, arrive sur cette paroi dans des conditions d'impact optimales.
