Abstract

L'INVENTION CONCERNE UN INJECTEUR DE CARBURANT POUR MOTEUR A COMBUSTION INTERNE, A INJECTION ET A COMPRESSION D'AIR, EQUIPE D'UNE AIGUILLE VENANT EN POSITION D'OUVERTURE, DECOLLANT DE SON SIEGE DE FORME CONIQUE, DANS UN PORTE-INJECTEUR, DANS LE SENS OPPOSE A CELUI DE L'ECOULEMENT DU CARBURANT, EQUIPE PAR AILLEURS D'UN CANAL DE SORTIE SE RACCORDANT AU SIEGE ET NE POUVANT ETRE OBTURE DU COTE PAR LEQUEL IL DEBOUCHE DANS LA CHAMBRE DE COMBUSTION. DANS LE SENS D'ECOULEMENT, LA PAROI DU CANAL DE SORTIE 4 COMPREND AU MOINS UNE ZONE DE DISCONTINUITE ETOU UNE ZONE EVASEE PROVOQUANT UN DECOLLEMENT DE L'ECOULEMENT. POUR RENDRE LE FONCTIONNEMENT DES INJECTEURS DE CARBURANT MOINS SUJET AUX DERANGEMENTS, L'INVENTION A POUR BUT D'EVITER LE CALAMINAGE DE L'ORIFICE DE SORTIE.THE INVENTION RELATES TO A FUEL INJECTOR FOR AN INTERNAL COMBUSTION ENGINE, WITH AIR INJECTION AND COMPRESSION, EQUIPPED WITH A NEEDLE COMING TO THE OPENING POSITION, TAKING OFF FROM ITS SEAT OF CONICAL SHAPE, IN AN INJECTOR HOLDER, IN THE OPPOSITE MEANING OF THE FLOW OF FUEL, ALSO EQUIPPED WITH AN OUTLET CHANNEL CONNECTING TO THE SEAT AND CANNOT BE OBSTRUCTED FROM THE SIDE BY WHICH IT OPENS INTO THE COMBUSTION CHAMBER. IN THE FLOW DIRECTION, THE WALL OF THE OUTPUT 4 CHANNEL INCLUDES AT LEAST ONE DISCONTINUITY ZONE AND OR A FLARED ZONE CAUSING A FLOW TAKE OFF. IN ORDER TO MAKE THE OPERATION OF THE FUEL INJECTORS LESS SUBJECT TO DANGER, THE AIM OF THE INVENTION IS TO PREVENT SIZING OF THE OUTLET PORT.
