Abstract

Buse d'injection de carburant liquide à prémélange qui comporte des fentes (24) d'entrée d'air longitudinales dans une chambre cylindrique (20). Un corps central (42) produit une zone de flux à augmentation axiale vers la sortie (32) de la chambre. Du carburant liquide est atomisé dans un endroit spécifié (58) adjacent au corps central conique (42). Cette zone présente une vitesse de cisaillement axiale élevée produisant une vaporisation intégrale et un mélange uniforme avant la combustion.
