Definitions

  • the invention relates to a sealing arrangement for a fuel injector, in particular the invention relates to a sealing arrangement for a nozzle retaining nut of a fuel injector, to ensure a fluid-tight connection between the fuel injector and a cylinder head. Furthermore, the invention relates to a nozzle retaining nut for a fuel injector.
  • a nozzle retaining nut holds the two main components of a fuel injector - an injector and a valve body - firmly together.
  • the injection nozzle protrudes in the assembled state of the fuel injector in a cylinder head into a combustion chamber of an automobile engine, wherein the valve body arranged above actuates the injection nozzle.
  • seal assembly At such a seal assembly high demands are made. On the one hand, it is exposed to high thermal loads, -40 ° C at cold start in winter to over + 150 ° C under operating conditions, and secondly high mechanical loads, in particular vibration loads. In addition, the seal assembly must ensure a durable sealing state between fuel injector and cylinder head with long-lasting loads.
  • both sealing surfaces must be machined very accurately in order to get the connection ever fluid-tight. Due to the lateral play to be provided between the fuel injector and the injector bore, no centering between the fuel injector and the injector bore is possible with this design, so that this must be done by means of other inputs or devices.
  • the angular difference of 2 ° to 5 ° is too small to prevent jamming and to ensure self-centering.
  • increasing the angular difference between the truncated cone on the nozzle retaining nut and the conical bore in the cylinder head to more than 5 ° smears would be made to the later seal quality, which can lead to leaks in the operation of the fuel injector.
  • the DE 101 02 192 A1 discloses fastener means for a fuel injector on a cylinder head, wherein the fuel injector within the cylinder head is surrounded by a sleeve which sealingly cooperates in cooperation with a sealing element of soft metal lying on a bottom of a stepped bore in the cylinder head.
  • the fuel injector should have a good self-centering when mounted in the cylinder head and produce a permanently fluid-tight connection between the fuel injector and the cylinder head in cooperation with the cylinder head. This should preferably be done by means of the nozzle retaining nut of the fuel injector.
  • the object of the invention is achieved by means of a sealing device or a sealing arrangement for a cylinder head and a fuel injector, in particular for a nozzle retaining nut of the fuel injector and the cylinder head, wherein the one component has a radially preferably completely encircling, extending in a longitudinal direction, concave cross-sectional profile, which on / in a sealing surface or sealing edge of a second component fluid-sealing attachable / einpressbar is.
  • the nozzle retaining nut of the fuel injector is configured with a radial and completely circumferential concave chamfer.
  • a sealing seat edge is horizontally extending within a stepped Injektorbohrung or tapered at an angle.
  • the concave chamfer and the sealing edge of the sealing seat edge interact in a special way.
  • a Vormontage- or centering state of the fuel injector is used with its nozzle lock nut in the Injektorbohrung without artificial forces acting on the fuel injector.
  • the dimensions of the nozzle retaining nut and the injector bore are selected such that the concave region or the concave chamfer of the nozzle retaining nut is seated against the sealing edge of the sealing seat edge of the injector bore.
  • the concave chamfer of the nozzle retaining nut sits only with a circle or a thin circular ring (centering state) on the edge of the sealing seat edge, as a result of which the nozzle clamping nut can not jam in the injector bore. Due to a low friction between the nozzle retaining nut and the cylinder head, the fuel injector is self-centering in the injector bore.
  • the concave chamfer preferably has the lowest possible coefficient of adhesion and / or sliding friction, as a result of which self-centering is still favored.
  • the sealing state between the fuel injector and the cylinder head can be assumed.
  • the fuel injector is pressed with a large static force in the Injektorbohrung or the sealing seat, which is formed in the bore, whereby the preferably harder relative to the cylinder head concave area the sealing seat edge preferably plastically deformed and pressed into the sealing seat edge is that a fluid-tight connection between the nozzle lock nut and the cylinder head is made.
  • a planar sealing section is formed between nozzle retaining nut and cylinder head, wherein due to the plastic deformation of the sealing seat rim, this adapts to the concave bevel and produces a high fluid pressure between the fuel injector and the cylinder head at high surface pressure. Furthermore, it is thereby possible to compensate for unevenness or small recesses in the surfaces. Such arrangements are permanently resistant to pressure undercurrents, so that a thermally and mechanically highly resilient seal assembly is realized with simultaneous long-term tightness.
  • the angle in the centering between a tangent to a contact point between the seat edge and Konkavfase, with the radially outwardly extending sealing seat edge is about 10 °, resulting in a good self-centering of the fuel injector in the cylinder head.
  • a tangent angle of a radially outer contact point between Konkavfase and sealing seat edge changes to the usual in the prior art 2 ° to 5 °.
  • the cylinder head or the sealing seat edge here are usually made of aluminum or magnesium.
  • the concave chamfer results in particular in the further inner radial region of the sealing seat edge an increased specific surface pressure, whereby the seal between the fuel injector and the cylinder head is improved over the prior art.
  • the highest surface pressure occurs at the inner region of the sealing seat edge, on which also the internal pressure of the combustion chamber rests; which is particularly advantageous, since a pressure infiltration can be effectively countered.
  • the voltage curve in the cylinder head is cheaper, resulting in fewer cracks in the cylinder head, which increases the durability of the cylinder head.
  • the introduction of force into the nozzle retaining nut is optimized over the prior art, which likewise results in a more favorable stress curve within the nozzle retaining nut.
  • a connecting line which in the centering state passes through the contact point of the concave chamfer with the sealing seat edge and through a peripheral point on the outer diameter of the concave region (in this case, the two points of the straight line and a longitudinal axis of the nozzle lock nut lie in one plane) a corresponding diametrically opposite straight line an angle of preferably about 108 ° or about 110 °.
