Abstract

L'invention a pour objet un injecteur pour moteur à combustion interne du type à aiguille prolongée par un téton pénétrant dans l'alésage d'injection. La longueur L de l'alésage d'injection est inférieure ou égale au diamètre D de cet alésage et, quand D est compris entre 0,8 et 1 mm, lorsque L est supérieur à la profondeur E de pénétration du téton 5 dans l'alésage 1, les rapports E/D et L/D doivent être >= 0,2 et <= 1. L'invention supprime l'accumulation des résidus et la cokéfaction à l'extrémité des injecteurs.The subject of the invention is an injector for an internal combustion engine of the needle type extended by a pin penetrating into the injection bore. The length L of the injection bore is less than or equal to the diameter D of this bore and, when D is between 0.8 and 1 mm, when L is greater than the depth E of penetration of the stud 5 into the bore 1, the E / D and L / D ratios must be> = 0.2 and <= 1. The invention eliminates the accumulation of residues and coking at the end of the injectors.
