Abstract
A gas turbine engine carburetor includes a fuel injector having a plurality of circumferentially spaced apart fuel outlets. A plurality of air swirlers (24) are circumferentially spaced apart around the fuel injector (22), with each swirler having a fuel inlet (24b) disposed in flow communication with a respective one of the fuel outlets for receiving fuel therefrom. Each swirler includes a plurality of swirl vanes to swirl air for mixing with the fuel from the fuel inlets. The multi-swirler carburetor having a common fuel injector increases injection points for reducing NO.sub.x emissions.
