Fuel injector

A fuel injector for an internal combustion engine comprising:

• a centerbody;
• a disposed radially outward of the centerbody to define an annular mixing section between the centerbody and the 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 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;
• a fuel conduit disposed in the centerbody for conducting the fuel to the fuel inlet;
• and
• a valve disposed in the fuel conduit for selectively controlling fuel injection into the mixing section, the valve being positioned sufficiently close to the fuel inlet to reduce a distance between the valve and fuel inlet.

A fuel injector for an internal combustion engine comprising:

• a centerbody;
• a casing disposed radially outward of the centerbody to define an annular mixing section between the centerbody and the casing;
• an air inlet of the mixing section for injecting at least a first portion of combustion air into the mixing section;
• a fuel inlet disposed in the centerbody for injecting fuel into the mixing section;
• a fuel conduit for conducting the fuel to the fuel inlet;
• a valve disposed in the fuel conduit for selectively controlling fuel injection into the mixing section;
• and
• an outlet of the mixing section for discharging a fuel/air mixture.
