Abstract

La présente invention concerne un dispositif d'injection de carburant possédant un appareil de chauffage formé par la disposition d'éléments de production de chaleur, disposés le long d'un trajet d'écoulement de carburant dans un corps de buse de sorte à être en contact avec le trajet d'écoulement de carburant. La production et la non-production de chaleur par les éléments de production de chaleur, qui forment l'appareil de chauffage, peuvent être contrôlées pour chaque élément de production de chaleur. En fonction des conditions de fonctionnement d'un moteur à combustion interne, l'appareil de chauffage chauffe le carburant dans le trajet d'écoulement de carburant à partir de son côté aval, qui est proche d'un orifice, par un volume équivalent à la quantité de carburant injectée la fois suivante. Seule une quantité nécessaire de carburant peut être chauffée et injectée.
