CA 2735157
The disclosure provides a fuel injection nozzle. The fuel injection nozzle includes a nozzle body, with the nozzle body defining a central bore. A fuel atomizer is disposed in the central bore. The fuel atomizer defines a spill-return bore and a swirl chamber. The swirl chamber is in fluid communication with the central bore. The spill-return bore includes a return swirler approximate the swirl chamber. An air supply pump is coupled to the fuel atomizer and is in fluid communication with the spill-return bore. The air supply pump is configured to selectively inject air into the swirl chamber through the spill-return bore.
L'invention concerne une buse à injection de carburant, qui comprend un corps de buse définissant un trou central. Un atomiseur de carburant se trouve dans ce trou et définit un trou de retour de trop-plein et une chambre à turbulence qui est en communication fluidique avec le trou central. Le trou de retour de trop-plein comprend un brasseur de retour proche de la chambre à turbulence. Une pompe d'alimentation en air est couplée à l'atomiseur et est en communication fluidique avec le trou de retour de trop-plein. Ladite pompe est conçue pour injecter sélectivement de l'air dans la chambre à turbulence via le trou de retour de trop-plein.
