摘要:
A fuel rail assembly of an internal combustion engine includes an axially extending non-round fuel conduit and at least one axially extending stiffening feature integral with said conduit. Integration of the stiffening features in the conduit enables reduction or elimination of the objectionable frequency noise radiated by the fuel rail assembly. By aligning the stiffening features axially relative to the conduit, panels having a relatively small surface area are formed and, thus, the noise radiating surface area is significantly reduced. The axial orientation of the added stiffening features allows the length of the stiffening features to be relatively large, which increases the stiffening effects to provide increased resistance to flexing, thus, reducing the noise radiated by the fuel system of the internal combustion engine.
