Title (DE) INJEKTOR FÜR GASFÖRMIGE KRAFTSTOFFE
(EN) INJECTOR FOR GASEOUS FUELS
(FR) INJECTEUR POUR CARBURANTS GAZEUX
Abstract:
(DE) Injektor (1) zum Eindüsen von gasförmigem Kraftstoff in einen Brennraum einer Brennkraftmaschine, mit eine Düsenkörper (2), in dem ein Druckraum (4) ausgebildet ist, der mit gasförmigem Kraftstoff unter einem Eindüsdruck befüllbar ist und von dem eine Eindüsöffnung (12) ausgeht, durch die der gasförmige Kraftstoff austreten kann. Vor der Eindüsöffnung (12) ist ein Umlenkkörper (15) so angeordnet, dass zumindest ein Teil des austretenden Gasstrahls (14) auf den Umlenkkörper (15) trifft und der austretende Gasstrahl (14) dadurch aufgefächert wird.
(EN) The invention relates to an injector (1) for injecting gaseous fuel into a combustion chamber of an internal combustion engine, comprising a nozzle element (2) in which a pressure chamber (4) is formed, which can be filled with gaseous fuel at an injection pressure and which has an injection opening (12) leading out of same, through which the gaseous fuel can pass out. A deflection element (15) is arranged in front of the injection opening (12) such that at least one portion of the outgoing gas flow (14) comes into contact with the deflection element (15) and the outgoing gas flow (14) is split in this way.
(FR) L’invention concerne un injecteur (1) destiné à injecter du carburant gazeux dans une chambre de combustion d’un moteur à combustion interne, comprenant un corps d’injecteur (2) dans lequel est formée une chambre de pression (4) qui peut être remplie de carburant gazeux sous une pression d’injection et de laquelle part une ouverture d’injection (12) à travers laquelle peut s’échapper le carburant gazeux. Un corps de renvoi (15) est disposé devant l’ouverture d’injection (12) de telle sorte qu’au moins une partie du jet de gaz (14) sortant vient frapper le corps de renvoi (15) et le jet de gaz (14) sortant est ainsi dispersé.
