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.

摘要： A precision fuel rail assembly for direct fuel injection comprising a plurality of formed parts first assembled and positioned loosely on a precision fixture, then joined (e.g. tack welded), by applying a BFM on all joints forming a “green” assembly and firing in a brazing oven, to produce a precision assembly formed from stainless steel parts. A bracket defining a sole plate for the assembly may be formed as a continuous element or a plurality of individual fuel rail brackets. Flanged sockets are attached to the bracket at locations corresponding to the fuel injector locations on an engine bank. Bolt holes are provided along the centerline of the sockets and fuel injectors. The bracket supports a fuel distribution tube via saddle elements disposed between the bracket and the tube. A jump tube supplies fuel from the distribution tube to each socket.

摘要： An internal pulse damper for use in a fuel rail for an internal combustion engine. The damper is formed from a length of tubular metal stock having a flat oval cross-section and ends flattened by crimping to form a captive-air pillow. The end crimps are improved through use of tooling to eliminate a creased sidewall area vulnerable to stress failure in prior art pulse dampers. Such tooling includes constraints to prevent the tubing sides from flaring out and forming a longitudinal crease adjacent the end crimp during squeezing-shut of the tube end.
