Claim 9:
10. An assembly for an engine, comprising:
a liner extending circumferentially about an axis, a combustion chamber formed by and radially within the liner, a first portion of the combustion chamber disposed to a first radial side of the axis, and a second portion of the combustion chamber disposed to a second radial side of the axis that is opposite the first radial side of the axis;
an outer wall extending circumferentially about and spaced radially from the liner;
a fuel line extending circumferentially within the outer wall;
an injector throat fluidly coupled with the fuel line, the injector throat angularly offset from a radial inner surface of the outer wall by an acute angle in a radial plane with respect to the axis, the injector throat configured to direct fuel received from the fuel line into the combustion chamber through a throat outlet;
a webbing projecting radially inward from the outer wall towards the liner, the webbing forming the injector throat, and the webbing configured with a triangular cross-sectional geometry in the radial plane; and
a compressor rotor comprising a plurality of compressor blades, the compressor rotor rotatable about the axis, wherein the injector throat extends to the throat outlet in a direction along the axis towards the compressor rotor;
wherein the triangular cross-sectional geometry has a first side, a second side and a third side;
the first side is at the outer wall and extends along the axis;
the second side is adjacent and extends parallel to the injector throat;
the third side forms a distal side of the webbing exposed to a plenum radially between the outer wall and the liner; and
the throat outlet is located on the third side and faces an opening in the liner, and the throat outlet is configured to inject the fuel into the opening in the liner through the plenum.
