Definitions

  • the present disclosure relates to a fuel rail assembly and a method of manufacturing a fuel adapter and a fixing bracket for a fuel rail assembly for an internal combustion engine.
  • Fuel rail assemblies for internal combustion engines utilising fuel injection are in widespread use, and comprise a fuel common rail, also known as a gallery, which forms a reservoir to which the fuel is supplied under high pressure by a fuel pump.
  • the fuel rail typically comprises an elongate body which has a fuel inlet at one end and a plurality of fuel outlets spaced along the fuel rail which are connected to the fuel injectors.
  • a fuel injector is provided for each cylinder of a multicylinder engine for injecting fuel directly into the combustion chamber. It is desirable for practical reasons for the fuel rail to be as close to the cylinder combustion chambers as possible to enable the passage of fuel from the fuel rail to the fuel injector to be as short as possible.
  • the fuel rail assembly is located in a position in a harsh environment where it is subjected to high temperatures, high pressures, and vibrations. Providing the necessary durability and reliability for the assembly is therefore a major problem.
  • the fuel outlets formed in the wall of the fuel rail are connected to a fuel injector adapter which is secured to the fuel rail so as to be in mechanical and hydraulic connection with a fuel injector.
  • the fuel injector is connected to the adapter through a fuel injector cup into which an inlet port of the fuel injector is inserted.
  • the fuel injector cups may be connected directly to the fuel rail or via pipe elements.
  • the fuel injector adapters may be secured to the fuel rail by a bonding technique such as brazing and this bonding is subject to the considerable pressures which exist in the fuel rail which can be 200 bar or even more.
  • the bonded connection is therefore a potential source of leakages and consequent failure.
  • the present disclosure seeks to provide a solution which mitigates the possibility of leakages and failure occurring.
  • a fuel rail assembly for an internal combustion engine, comprising an elongate fuel rail having a fuel inlet, and a plurality of fuel outlets spaced along the fuel rail.
  • the fuel outlets are adapted to be in hydraulic communication with a fuel injector by which fuel is injected into the engine.
  • the fuel outlets are shaped and arranged to provide a fluidic connection from the fuel rail to the fuel injector.

  • the fuel adapter provides a mechanical connection to the fuel rail
  • the fuel adapter is in direct mechanical contact with the fuel rail.
  • That "the fuel adapter provides a hydraulic connection to the fuel rail” means in particular that the fuel adapter is in fluidic connection to the fuel rail so that fluid can flow from the fuel rail into - and in particular through - the fuel adapter.
  • Said surface of the fuel adapter may, in some embodiments, be shaped to provide an exterior face to match a profile surface on the fuel rail.
  • the fuel adapter has a tubular shape with a curved external circumferential surface comprising the exterior face, the curvature of the exterior face being smaller than the curvature of surface sections following the exterior face in both circumferential directions.
  • the circumferential surface is in the shape of an elliptical cylinder, the semi-major axis of which is parallel to an elongation direction of the fuel rail and the semi-minor axis of which is perpendicular to the elongation direction of the fuel rail.
  • the fuel adapter has a cylindrical shape with a flattening representing the exterior face. The flattening may extend along the entire length of the fuel adapter in direction of its cylinder axis in one embodiment.
  • the fuel adapter may have an elongate shape with a first axis or length that is longer than a second axis or length.
  • the fuel adapter may have a substantially elliptical form or rectangular form when viewed from above.
  • the expression "viewed from above” is in particular understood to indicate a top view along an installation direction in which the fuel injector is insertable into the fuel adapter or into a fuel injector cup which may be fixed to (or in one piece with) the fuel adapter.
  • the installation may expediently be perpendicular to an elongation direction of the fuel rail.
  • Either the longer axis or length or the shorter axis or length may include the exterior face which is secured to the fuel rail.
  • the exterior face and the fuel adapter may be secured to the fuel rail by brazing such that the fuel rail assembly comprises a brazed joint at the interface between the exterior face of the fuel adapter and the profile surface of the fuel rail.
  • a brazed joint with a more uniform thickness than e.g. with a circular cylindrical fuel adapter can be formed between this exterior face of the fuel adapter and the profile surface on the fuel rail.
  • a brazed joint with a more uniform thickness may be used to improve the reliability of the brazed joint.
  • the fuel rail assembly may further comprise one or more fixing brackets for securing the fuel rail assembly to an engine.
  • the or each bracket may have a surface shaped to provide an exterior face shaped to match a profile surface on the fuel rail by which the fixing bracket is secured by brazing to the fuel rail.
  • the fixing bracket may have a tubular shape with a curved external circumferential surface comprising the exterior face, the curvature of the exterior face being smaller than the curvature of surface sections following the exterior face in both circumferential directions.
  • the shape of the exterior face and the profile surface of the fuel rail may be used to increase the area of the interface between the fixing bracket and the fuel rail and increase the area of the brazed joint formed between the two parts.
  • the fixing bracket is integrally formed with a fuel adapter, wherein the fuel adapter may be a fuel adapter according to one of the embodiments, developments and examples described above.
  • the or each adapter incorporates a fuel injector cup for receiving an inlet port of a fuel injector.
  • the tubular shape of the fuel adapter has a closed axial end and an open axial end, the fuel injector cup being fluid-tightly fixed to the open axial end.

  • the cylinder axes of said circumferential surface and of the adapter and of the profile surface may be mutually perpendicular and in particular skew.
  • This arrangement has the advantage that a particularly large surface area is provided between the fuel rail and the adapter which increases the bonding area between the two components. This increases the strength of the bonding between the components.
  • the disclosure may also be adapted to secure a mounting bracket or brackets to the fuel rail by which the fuel rail is secured to the engine in the installed condition.
  • Each bracket is shaped to provide an exterior face shaped to match a mating profile surface on the fuel rail by which surface the bracket is secured by a bonding technique such as brazing to the fuel rail.
  • the bracket is formed with the said exterior face by mechanical deformation of the material of the bracket.
  • the exterior face is formed by machining into the material of the bracket
  • the fixing bracket is formed by deforming a circular cylindrical member, such as a tube, into a generally elliptical cylindrical shape having said exterior face in the elliptical face. In this way, a greater surface area is formed in the mating surfaces between the two components which greatly increases the bonding area available to strengthen the bond between the two components.
