Abstract

L’invention concerne un dispositif d'injection de carburant pour moteur à combustion interne comprenant : - un conduit d’écoulement (5) du carburant s'étendant selon une direction d'écoulement; - un insert gicleur (6), dans lequel l’insert gicleur (6) comprend : - un corps cylindrique (10) positionné dans le conduit d’écoulement (5), - un canal (11) traversant de part en part le corps cylindrique (10); et dans lequel le corps cylindrique (10) comporte successivement dans la direction d’écoulement une portion emmanchée (12) qui est emmanché en force dans une partie d’emmanchement (8) du conduit d’écoulement (5) et une portion guidée (13) destinée à coopérer avec une partie de guidage (9) du conduit d’écoulement (5) de sorte à guider le mouvement dudit corps cylindrique (10) dans le conduit d’écoulement (5) avant l’emmanchement en force, la portion guidée (13) comportant un diamètre extérieur qui est inférieur à un diamètre extérieur de la portion emmanchée (12), et dans lequel un ratio entre le diamètre extérieur de la portion emmanchée (12) et une dimension de la portion guidée (13) dans la direction d’écoulement est compris entre 0,33 et 1.
