摘要：
A combustion section 100 for a heat engine 10 has an outer casing 64 with an inner pressure plenum 66. A liner assembly 115 radially inward of the outer casing forms a combustion chamber 62, and the plenum is arranged around the liner assembly. A fuel injector body 203 is coupled to both the outer casing and the liner assembly, and the body has a first inlet opening 221 through a first wall (231 Fig. 5) and a second inlet opening (222 Fig. 5) through a second wall (232 Fig. 4). A mixing passage (207 Fig. 9) is fluidly connected to the inlets and to an outlet 205, and in use supplies a flow of fuel-oxidizer mixture 186 to the combustion chamber, with the first and second inlets receiving the oxidizer from the pressure plenum. The outlet may be a slot, and several fuel injector assemblies 200 may be arranged adjacent to each other. The combustion section may be at least one of a combustor-diffuser assembly, an afterburning system, an inter-turbine combustion system, and there may be multiple first inlets and second inlets. The combustion section is able to accommodate a fuel injector that provides a relatively shorter fuel injector that is less prone to coking or aero/thermal loading.

opening and the inlet passage at the second inlet opening along the tangential direction.
13. The combustion section of any of claims 1 to 12, wherein the body comprises a third wall extended at least partially along the radial direction, and wherein a fuel passage is defined through the third wall.
14. The combustion section of any of claims 1 to 13, wherein the body defines a plurality of first inlet openings and a plurality of second inlet openings each in adjacent arrangement along the longitudinal direction, and wherein the body defines a plurality of third inlet openings between one or both of the first inlet openings or second inlet openings along longitudinal direction.
