Title (EN) DUAL FUEL INJECTION VALVE
(FR) SOUPAPE D'INJECTION DE DEUX CARBURANTS
Abstract:
(EN) A dual fuel injection valve with concentric needles comprises an inner needle and an outer needle surrounding the inner needle, both needles being located inside the injection valve body. The valve is provided with a first set and a second set of orifices for separately injecting two different fuels directly into the combustion chamber of an internal combustion engine. The outer needle is fixed against rotation with respect to the injection valve body such that an interlace angle between the centerlines of the first series of orifices and second series of orifices is set at different predetermined angles to reduce methane emissions.
(FR) Une soupape d'injection de deux carburants dotée d'aiguilles concentriques comprend une aiguille intérieure et une aiguille extérieure entourant l'aiguille intérieure, les deux aiguilles se situant à l'intérieur du corps de soupape d'injection. La soupape est dotée d'un premier ensemble et d'un second ensemble d'orifices destinés à injecter séparément deux carburants différents directement dans la chambre de combustion d'un moteur à combustion interne. L'aiguille extérieure est fixée contre rotation par rapport au corps de soupape d'injection de sorte qu'un angle d'entrelacement entre les lignes médianes de la première série d'orifices et de la seconde série d'orifices soit réglé sur différents angles prédéfinis afin de réduire les émissions de méthane.
