Abstract
L'objet de l'invention est d'obtenir une soupape d'injection qui permette à la quantité de carburant injecté de se volatiliser aussi rapidement et complètement que possible. A cet effet, l'ouverture (53) de l'injecteur se situe à l'extrémité d'un conduit cylindrique (52) et est formée d'un orifice central (530) entouré d'orifices périphériques regroupés (531). On obtient ainsi lors de l'injection un jet de carburant finement réparti et ayant donc une grande surface, ce qui facilite la volatilisation du carburant injecté.The object of the invention is to obtain an injection valve which allows the quantity of fuel injected to volatilize as quickly and completely as possible. To this end, the opening (53) of the injector is located at the end of a cylindrical conduit (52) and is formed by a central orifice (530) surrounded by grouped peripheral orifices (531). There is thus obtained during injection a finely distributed fuel jet and therefore having a large surface area, which facilitates the volatilization of the injected fuel.
