Abstract

La présente invention se rapporte à un injecteur de carburant gazeux ou liquide basé sur des "buses de type à vanne différentielle", à ouverture vers l'intérieur et à injection directe, qui possède de plus grandes vitesse et fréquence de fonctionnement grâce à l'utilisation d'un ensemble de fermeture de vanne à ultra-faible inertie ("aiguille" 10) dont l'avantage est de pouvoir s'utiliser, entre autres, dans des injecteurs de carburant populaires de type à buse de type de type VCO et SAC commandés à partir d'une source à rampe de combustible. Le fonctionnement à grande vitesse et à flux de retour négligeable en termes de fuite de carburant de ladite buse est possible grâce à l'unité de soupape de mesure piézoélectrique (29) à haute vitesse s'ouvrant vers l'extérieur, le flux de retour pouvant être entièrement éliminé par l'application d'un venturi, de préférence dans l'injecteur de carburant, à l'intérieur de sa pointe d'aiguille de vanne. L'invention permet l'injection simultanée de n'importe quel gaz ou liquide tel que le GNL, le diesel et l'eau, selon le cycle. Fig. 14 : rien à traduire
