Abstract

Une méthode et un appareil de dilution de carburant pour réduire les oxydes d'azote à l'aide d'un dispositif de dilution de carburant qui inclue : un premier conduit possédant une entrée et une sortie, le premier conduit de transmission d'un écoulement continu de carburant qui entre puis sort dans un premier état thermodynamique et un premier indice de carburant; et un second conduit doté d'une admission et d'une voie de sortie, le second conduit pour transmettre un écoulement continu de liquide accédant par l'admission et quittant par la voie de sortie dans un second état thermodynamique différent et un second indice de carburant différent du premier indice de carburant d'au moins environ 0,1; la sortie du premier conduit et la voie de sortie du second conduit définissant un lieu de mélange proche de la sortie et de la voie de sortie pour mélanger l'écoulement continu de carburant et l'écoulement continu du liquide pour générer un écoulement continu de carburant dilué ayant un indice de carburant intermédiaire; et une buse de fermeture pour transmettre au moins une partie de écoulement continu de carburant dilué par la buse de fermeture.
