Abstract

L'invention concerne un collecteur d'admission d'air délimitant un conduit d'air primaire et au moins deux conduits d'air secondaires. Le conduit d'air primaire possède une extrémité d'entrée conçue pour recevoir de l'air provenant d'une alimentation en air et une extrémité de sortie en communication fluidique avec chaque conduit d'air secondaire. Chaque conduit d'air secondaire possède une extrémité d'entrée conçue pour recevoir de l'air directement en provenance de l'extrémité de sortie du conduit d'air primaire et une extrémité de sortie conçue pour fournir de l'air à un ou plusieurs cylindres d'un moteur à combustion interne. Un trajet de fluide est délimité dans chaque conduit d'air secondaire, et ces trajets de fluide sont sensiblement de même longueur.
