Patent abstract
A fuel injector system provides an air assist fuel nozzle which includes a fuel shroud and an air portion. Air passes around the fuel shroud to air jets in the air portion to provide a focused application of air directly onto a fuel spray from each of a multiple of main fuel jets to impart additional velocity to the fuel as it is flowing out of the fuel nozzle. The air jets increase the resulting fuel spray velocity to a level high enough to reach a prefilmer wall of a swirler even during snap deceleration conditions.
