Abstract

Iniettore in cui un elemento otturatore controllato da un attuatore elettromagnetico controlla la formazione di almeno un getto di combustibile attraverso un foro di atomizzazione, caratterizzato dal fatto di essere provvisto di mezzi di atomizzazione ausiliaria includenti almeno una superficie disposta trasversalmente obliqua rispetto al detto getto di combustibile, ad una distanza dal foro di atomizzazione prefissata e relativamente grande rispetto al diametro del getto, in modo che la superficie sia colpita dal getto in un punto prefissato e con un angolo d'impatto diverso da 0° e da 90°, ed includenti inoltre almeno un condotto per un getto d'aria ausiliaria orientato in modo da dirigere il getto di aria contro la detta superficie obliqua, sostanzialmente in corrispondenza del punto d'impatto su essa del detto getto di combustibile.(Figure 1 e 2).Injector wherein a shutter element controlled by an electromagnetic actuator controls the formation of at least one jet of fuel through an atomization hole, characterized in that it is equipped with auxiliary atomization means including at least one surface transversely arranged obliquely with respect to said fuel jet , at a predetermined distance from the atomization hole and relatively large with respect to the diameter of the jet, so that the surface is hit by the jet at a predetermined point and with an impact angle different from 0 ° and 90 °, and also including at least a duct for an auxiliary air jet oriented so as to direct the air jet against said oblique surface, substantially at the point of impact on it of said fuel jet (Figures 1 and 2).
