Abstract: A duct assembly for a fuel injector of an engine includes a base and multiple duct bodies. The base includes a number of spaced apart receptacles. Each receptacle defines a cavity with a receptacle axis, a rotational engagement surface, and an axial engagement surface. The duct bodies are correspondingly secured within the cavities. Each duct body defines an axis and a duct extending along the axis to provide a passage for a fuel jet from the fuel injector. Each duct body defines an axial alignment surface engaging the axial engagement surface of the receptacle in which it is disposed to axially align the duct body along the receptacle axis of the corresponding receptacle.

Abstract: A method of forming a feature on a tube having a wall is provided. The wall defines an outer surface and an inner surface. The method includes forming, via a processing device, a Three Dimensional (3D) model of the feature. The method further includes slicing, via the processing device, the 3D model of the feature into a plurality of model layers. The method also includes regulating, via the processing device, a dispensing member to deposit a plurality of layers of a material on the outer surface of the tube to form the feature. The plurality of layers of the material correspond to the plurality of model layers. The method further includes forming, via a machining process, a hole in the wall of the tube to communicate an interior of the feature with an interior of the tube.
