Abstract:
1. A fuel injector for an internal combustion engine comprising: a centerbody; a first casing disposed radially outward of the centerbody to define an annular mixing section between the centerbody and the first casing; an axial air inlet at an upstream end of the mixing section for axially injecting a first portion of combustion air into the mixing section; a radial air inlet disposed in the first casing for radially injecting a second portion of combustion air into the mixing section; a fuel inlet disposed in the centerbody downstream of the axial air inlet for injecting fuel into the mixing section; and a vortex generator disposed in the mixing section for producing axially extending vortices with the second portion of the combustion air radially injected into the mixing section to promote mixing of the injected fuel with the first and second portions of the injected combustion air to generate a fuel/air mixture at an outlet of the fuel injector.
