Abstract
An assembly is provided for an engine. This engine assembly includes an engine structure and a fuel injector. The engine structure includes an injector receptacle and a fuel supply passage. The injector receptacle extends longitudinally through the engine structure along a centerline. The fuel supply passage extends laterally within the engine structure to the injector receptacle. The fuel injector is mated with the injector receptacle. The fuel injector includes a nozzle passage and a nozzle outlet. The nozzle passage spirals about the centerline within the fuel injector towards the nozzle outlet. The nozzle passage fluidly couples the nozzle outlet to the fuel supply passage.
Claims18
An assembly for an engine, comprising:
- an engine structure including an injector receptacle and a fuel supply passage, the injector receptacle extending longitudinally through the engine structure along a centerline, and the fuel supply passage extending laterally within the engine structure to the injector receptacle;
- and
- a fuel injector mated with the injector receptacle, the fuel injector including a fuel nozzle and a splash plate, the fuel nozzle including an internal bore, a nozzle passage, and a nozzle outlet, the internal bore projecting longitudinally along the centerline within the fuel nozzle to the nozzle passage, the nozzle passage spiraling about the centerline within the fuel injector from the internal bore to the nozzle outlet, the nozzle passage fluidly coupling the nozzle outlet to the fuel supply passage, the splash plate disposed at a distal end of the fuel nozzle and laterally overlapping the nozzle outlet, and the splash plate extending longitudinally along the centerline.
An assembly for an engine, comprising:
- an engine structure including an injector receptacle and a fuel supply passage, the injector receptacle extending longitudinally through the engine structure along a centerline, and the fuel supply passage extending laterally within the engine structure to the injector receptacle;
- and
- a fuel injector mated with the injector receptacle and attached to the engine structure by a threaded interface, the fuel injector configured as a monolithic body and including a fuel nozzle and a splash plate, the fuel nozzle including an internal bore, a nozzle passage, and an annular nozzle outlet, the splash plate comprising a frustoconical splash plate surface extending longitudinally along the centerline and circumferentially overlapping the annular nozzle outlet, and the fuel injector configured to direct fuel, received by the nozzle passage from the fuel supply passage, out of the fuel nozzle to impinge against the frustoconical splash plate surface;
- wherein the internal bore projects longitudinally along the centerline within the fuel nozzle to the nozzle passage, and the nozzle passage spirals about the centerline within the fuel injector from the internal bore to the nozzle outlet.
An assembly for an engine, comprising:
- an engine structure including an injector receptacle, a fuel supply passage and a combustion chamber, the injector receptacle extending longitudinally through the engine structure along a longitudinal centerline to the combustion chamber, the fuel supply passage extending laterally within the engine structure to the injector receptacle, and the longitudinal centerline parallel with or angularly offset from a centerline axis of the engine structure by less than fifteen degrees;
- and
- a fuel injector mated with the injector receptacle and attached to the engine structure by a threaded interface, the fuel injector including a fuel nozzle and a splash plate, the fuel nozzle including an internal bore, a nozzle passage, and a nozzle outlet, the internal bore projecting longitudinally along the centerline within the fuel nozzle to the nozzle passage, the nozzle passage comprising a spiral nozzle passage, the nozzle passage extending longitudinally along the centerline within the fuel injector from the internal bore to the nozzle outlet, the nozzle passage fluidly coupling the nozzle outlet to the fuel supply passage, the splash plate integral with the fuel nozzle, and the splash plate extending longitudinally along the centerline, and the splash pate extending laterally within the nozzle outlet.
