1. An assembly for an engine, comprising:
an engine structure comprising an injector receptacle and a fuel supply passage, the injector receptacle extending longitudinally through the engine structure along a centerline, the injector receptacle comprising an injector aperture and a protrusion aperture, and the fuel supply passage extending laterally within the engine structure to the injector aperture; and
a fuel injector mated with the injector receptacle, the fuel injector comprising a nozzle passage, a nozzle orifice, a base and a protrusion, the nozzle passage extending longitudinally along the centerline within the fuel injector to the nozzle orifice, the nozzle passage fluidly coupled with the fuel supply passage, the base extending longitudinally along the centerline in the injector aperture, the protrusion formed integral with the base, and the protrusion projecting laterally out from the base into the protrusion aperture;
the fuel injector configured to translate longitudinally along the centerline when being inserted into the injector receptacle;
wherein the protrusion aperture is a first protrusion aperture, and the infector receptacle further comprises a second protrusion aperture;
wherein the protrusion is a first protrusion, and the fuel injector further comprises a second protrusion; and
wherein the second protrusion is formed integral with the base, and the second protrusion projects laterally out from the base into the second protrusion aperture.
 
5. An assembly for an engine, comprising:
an engine structure comprising an injector receptacle, the injector receptacle extending longitudinally through the engine structure along a centerline;
a fuel injector received by the injector receptacle, the fuel injector including a fuel nozzle and a splash plate, and the fuel nozzle configured to direct fuel out of the fuel injector to impinge against the splash plate; and
a fastener projecting laterally through a sidewall of the engine structure into the fuel injector to secure the fuel injector to the engine structure;
wherein the engine structure further comprises a fuel supply passage extending laterally within the engine structure to the injector receptacle;
wherein the fuel injector comprises a nozzle passage and a nozzle orifice in the fuel nozzle, the nozzle passage extends longitudinally along the centerline within the fuel injector to the nozzle orifice, and the nozzle passage is fluidly coupled with the fuel supply passage;
wherein the injector receptacle extends longitudinally through the engine structure along the centerline between a first end and a second end; and
wherein the fuel supply passage extends laterally within the engine structure to an intermediate region of the injector receptacle located longitudinally along the centerline between the first end and the second end.
