Title (EN) INTERNAL COMBUSTION ENGINE FUEL INJECTING DEVICE
(FR) DISPOSITIF D'INJECTION DE CARBURANT POUR MOTEUR A COMBUSTION INTERNE
Abstract:
(EN) The invention concerns an internal combustion engine fuel injecting device (1) connected to a circuit (2) supplying fuel under adapted pressure, said injector (1) comprising an injection nozzle (8) at the end (14) of which is arranged at least an aperture for injecting fuel (10). The invention is characterised in that said injector (1) co-operates with cyclic vibration means (6) controlled by the engine electronic control system to cause the injection nozzle (8) to vibrate, said injection nozzle (8) being adapted to eject a predetermined amount of fuel at each one of its oscillations.
(FR) Dispositif d'injection de carburant pour moteur à combustion interne comprenant un injecteur (1) relié à un circuit (2) d'alimentation en carburant sous une pression adaptée, ledit injecteur (1) comportant une buse d'injection (8) à l'extrémité (14) de laquelle est ménagé au moins un orifice d'injection de carburant (10), caractérisé en ce que ledit injecteur (1) coopère avec des moyens de mise en vibration cyclique (6) pilotés par le système électronique de contrôle moteur de façon à provoquer la vibration de la buse d'injection (8), ladite buse d'injection (8) étant adaptée pour éjecter une quantité de carburant prédéterminée à chacune de ses oscillations.
