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.
