Fuel injector assembly for a heat engine

A fuel injector assembly, the fuel injector assembly comprising:

• a body defining a first inlet opening and a second inlet opening spaced apart from one another along a first direction, wherein the body further defines a fuel-oxidizer mixing passage therewithin extended along a second direction at least partially orthogonal to the first direction, and wherein the first inlet opening and the second inlet opening are each in fluid communication with the fuel-oxidizer mixing passage, and further wherein the body defines an outlet opening at the fuel-oxidizer mixing passage at a distal end relative to the first inlet opening and the second inlet opening, wherein the first inlet opening and the second inlet opening are each configured to admit a flow of oxidizer to the fuel-oxidizer mixing passage, wherein the fuel-oxidizer mixing passage is configured to provide a flow of fuel-oxidizer mixture to a combustion chamber via the outlet opening, and wherein the body defines the outlet opening as a slot extended at least partially along a third direction orthogonal to the first direction and the second direction.
