Definitions

  • the invention relates to a cylinder head and to it mounted injector as used in automotive engineering Find use.
  • the invention has for its object a cylinder head and an injector mounted on it with a small one Specify noise emissions with which the above Disadvantages can be avoided.
  • a cylinder head and a injector mounted thereon with the following features: It is a Means for tensioning are provided through which the injector at least one connection point against the cylinder head is excited. At the junction between the injector and a first damping element is arranged on the cylinder head which essentially consists of one of the materials graphite, Polyformaldehyde, polytetrafluoroethylene, memory metal.
  • the transmission of Structure-borne noise from the injector to the cylinder head is strong dampened, so that the airborne sound radiation from the cylinder head is also strongly dampened.
  • the material of the first damping element must be sound absorbing act and at the same time be resistant to pressure, because at the Connection point through the means for tensioning the injector against the cylinder head with a high force, which is usually is between 4 and 12 kN.
  • a flowing of the materials mentioned with high force can be used especially with a positive connection Avoid backing material well.
  • a memory metal is, for example, AlCu titanate.
  • the thickness of the first damping element is preferably about 1/10 mm to 10mm.
  • the cylinder head has an opening for one Combustion chamber on.
  • the injector is in the opening inserted that the injector nozzle towards the combustion chamber is directed.
  • the cylinder head faces inside the opening a paragraph that forms the junction and against the the injector is cocked.
  • the first Damping element arranged.
  • the first damping element is for example, disc-shaped.
  • the means for clamping can be on the injector and on the cylinder head be attached.
  • another damping element arranged which essentially consists of one of the materials Graphite, polyformaldehyde, polytetrafluoroethylene, memory metal consists. It also applies to the further damping element that it should have a sound-absorbing effect as well as against high pressures should be resistant.
  • the means for tensioning is on the injector not attached to the cylinder head. Instead, that's the means attached to another component for clamping, on which one Force can be applied by which the injector against the Cylinder head can be clamped.
  • the means for clamping can have a clamping claw. On upper part of the injector protruding from the opening, in this case is covered by the clamp. The upper Part of the injector has a paragraph against which the Clamping claw pushes down.
  • the means of tension can have a connecting means through which the clamping claw on Cylinder head is fixed and with which the distance between the clamping claw and the cylinder head can be adjusted. With the help of the connecting means, the distance between the clamping claw and the cylinder head and thus the force with the injector is clamped on the cylinder head can be set.
  • a second damping element is arranged.
  • the fourth damping element no component has to enclose, it does not require a recess and can be cylindrical or cuboid, for example be designed.
  • the connecting means can be designed as a screw, which is passed through an opening in the clamping claw.
  • the The head of the screw is arranged over the clamping claw and presses down against the clamp.
  • the thread of the The screw is screwed into the cylinder head.
  • Between the The head of the screw and the claw is preferably a third damping element arranged, which consists of one of the Materials consists of which the first damping element can exist.
  • the figure shows a cross section through part of a Cylinder head and an injector mounted thereon with a first opening, a second opening, a first Damping element, a second damping element, one third damping element, a fourth damping element, a screw, a clamp, a first paragraph and a second paragraph.
  • a cylinder head Z which has a first opening O1 into which a lower part of a Injector I is inserted (see figure).
  • the cylinder head Z has inside the first opening O1 a first paragraph A1 against which the injector I cocked is.
  • the first damping element D1 is disk-shaped and has a thickness of approx. 1/10 mm.
  • a clamping claw S is provided, which has an upper part of the injector I, which from the first opening O1 of the Cylinder head Z protrudes, includes.
  • the upper part of the Injector I has a second paragraph A2 against which the Clamping claw S presses down.
  • a second disc-shaped damping element D2 made of graphite with a Thickness of approx. 1/10 mm arranged.
  • the clamping claw S has a second opening O2 through which a screw SB is guided, the head of which over the clamping claw S is arranged, and the thread in the cylinder head Z is screwed in.
  • a third disc-shaped one Damping element D3 made of graphite with a thickness of approx. 1/10 mm arranged.
  • fourth damping element D4 made of graphite with a thickness of arranged about 1/10 mm.
  • the fourth damping element D4 has the shape of a cylinder.
