Title (EN) FUEL INJECTOR ASSEMBLY HAVING DUCT STRUCTURE
(FR) ENSEMBLE INJECTEUR DE CARBURANT AYANT UNE STRUCTURE DE CONDUIT
Abstract:
(EN) A fuel injector assembly (142) for an engine (100). The engine (100) includes a cylinder head (104) defining a through-hole (140). The fuel injector assembly (142) includes an insert (150), having a first end (152) and a second end (154), configured to be received within the through-hole (140) and coupled to the cylinder head (104). The insert (150) defines a bore (162) extending from the first end (152) to the second end (154). The fuel injector assembly (142) further includes a fuel injector (180) including a plurality of orifices (184), received within the bore (162) of the insert (150); and a duct structure (170) including a plurality of ducts (174), coupled to the insert (150) such that the plurality of ducts (174) align with the plurality of orifices (184) to at least partially receive one or more fuel jets (186) from the plurality of orifices (184) of the fuel injector (180).
(FR) L'invention concerne un ensemble injecteur de carburant (142) destiné à un moteur (100). Le moteur (100) comprend une culasse (104) qui délimite un trou traversant (140). L'ensemble injecteur de carburant (142) comprend un insert (150), ayant une première extrémité (152) et une seconde extrémité (154), conçu pour être reçue à l'intérieur du trou traversant (140) et accouplé à la culasse (104). L'insert (150) délimite un alésage (162) s'étendant de la première extrémité (152) à la seconde extrémité (154). L'ensemble injecteur de carburant (142) comprend en outre un injecteur de carburant (180) comprenant une pluralité d'orifices (184), reçus dans l'alésage (162) de l'insert (150) ; et une structure de conduit (170) comprenant une pluralité de conduits (174), accouplés à l'insert (150) de sorte que la pluralité de conduits (174) s'alignent avec la pluralité d'orifices (184) pour recevoir au moins partiellement un ou plusieurs jets de carburant (186) à partir de la pluralité d'orifices (184) de l'injecteur de carburant (180).
