Definitions
- the invention relates to a damping device for the arrangement between a cylinder head and an injector mounted thereon, in particular in the region of the injector nose and a damping element for arrangement between a cylinder head and an injector mounted thereon, in particular in the region of the injector.
- the fuel is usually injected by means of an injector into the combustion chamber, for this purpose the cylinder head of the internal combustion engine has a dome opening into the combustion chamber, in which the injector is accommodated.
- the injector In the intermittent injection during operation of the internal combustion engine - caused by the opening and closing of the injector - strong vibrations that negatively affect the comfort and acoustic behavior.
- the injector In particular, at elevated fuel pressures, as prevail in direct injection systems in gasoline and diesel engines, occurs an increased vibration load.
- modern combustion methods in which multiple injection takes place during the intake and compression stroke, contribute in particular to the unwanted development of noise and vibration.
- the invention is therefore based on the object to improve an aforementioned damping device or an aforementioned damping element to the effect that in addition to an effective damping, a decoupling of the injector from the cylinder head, even small dimensional tolerances and a positionally accurate determination of the injector are achieved with respect to the cylinder head , In addition, an elastic and / or plastic deformation of the damping element over its lifetime should be avoided.
- a solution of the object is achieved with a damping device having the features of claim 1, wherein the underlying idea comprises a multi-part construction of the damping device.
- the multi-part construction makes it possible to integrate other functions in addition to the damping in the damping device.
- Another solution of the same object is achieved with a damping element having the features of claim 11 by designing the damping element as a metal cushion.
- the damping device has a first partial function range, which is essentially suitable for damping, and a second partial function range, which is suitable essentially for positionally accurate fixing.
- the first sub-functional area comprises a damping element due to its material property and / or configuration. It has proved to be advantageous to use a metal pad of a wire mesh, which optionally comprises coated wires and / or plastic fibers. In addition to the material used, the special damping property also results from the particular design and / or the structure of the first partial function range. In the metal pad made of wire mesh, a very high energy dissipation due to the friction between the wires, the degree of damping can be increased by coating the wires and / or woven plastic threads. Particularly advantageous in conjunction with the good damping property, the mechanical dimensional stability of the metal pad.
- the first sub-functional area is designed annularly, having an at least approximately rectangular or square cross-section.
- the second partial function region comprises a first injector-side part and a second cylinder-head-side part, wherein the first and the second part of the second partial function region are interconnected by means of the first partial function region. What is essential in this connection is the decoupling of the first and second parts of the second subfunction area.
- the first part of the second partial function region is configured as an inner ring, encompassing the first partial function region on the inside and the injector side, and the second part of the second partial functional region as outer ring, embracing the first partial functional region on the outside and on the cylinder head side. Due to its shell-like configuration, the second part of the second partial function region is suitable for absorbing, for example, abrasion from the metal pad made of wire mesh or other particles, so that it is advantageously prevented that particles enter the combustion chamber.
- the second part of the second partial function region is arranged between the cylinder head and the first partial function range, wear on the cylinder head is avoided by abrasion and at the same time increases the damping effect.
- first and the second part of the second sub-functional area are connected by means of a clamping fit with the first sub-functional area.
- the metal cushion preferably consists of a wire mesh or of a metal foam.
- a further improvement of the damping property can be achieved by the metal pad comprising coated wires and / or plastic fibers and / or graphite.
- the metal pad is annular, having an at least approximately rectangular or square cross-section, configured, so that particularly in connection with the selected material of the damping element, a particularly high positional and dimensional accuracy between injector and cylinder head is achieved.
- 1 a shows a damping device in a side view, cut
- FIG. 1b shows a damping device in plan view
- Figure 4 shows a cylinder head mounted thereon fuel injector and damping device.
- the damping device 100 comprises an annular damping element 102 with a square or rectangular cross section, so that two parallel contact surfaces 101, 103 and an annular outer surface 105 and an annular inner surface 107 are formed.
- the damping element 102 which forms a first part functional area, is presently formed as a metal pad from a compressed wire mesh and consists of a stainless steel.
- other materials can be used, the one have a large dissipation factor, ie the property of converting a large proportion of mechanical energy into heat through internal friction.
- elastomeric plastics, special iron-manganese alloys, metal-effect shape memory alloys or graphite-containing materials may also be used.
- the damping element 102 is enclosed by an inner ring 104 and an outer ring 106, which together form a second partial function region for positionally accurate fixing. Both the inner ring 104 and the outer ring 106 are positively connected to the damping element 102, for example in clamping connection, but decoupled from each other by each remaining free gaps 109, 111 are formed. In order to prevent, for example, abrasion of the damping element 102 from reaching the outside, the damping element 102 can also be completely encapsulated by sealing the gaps 109, 111. In this case, preferably, the gap seal is similar compressible, as the damping element 102. Such a gap seal can be made as a bellows made of metal or plastic.
- the inner ring 104, 204 is shown in FIG. It is annular, angularly configured so that a disk-shaped region 212 for injector-side contact with the abutment surface (FIG. 1a: 101) of the damping element and an annular region 210 for abutment with the inner surface (FIG. 1a: 107) of the damping element are formed.
- spring tongues 216 are provided. By means of the spring tongues 216, the damping element can be connected to an injector, so that an assembly is facilitated and it is avoided that the installation of the damping element is forgotten.
- the outer ring ( Figure 1: 106) of the damping device is shown in Figure 3 and designated 306 there.
- the outer ring 306 is also configured annularly with an angular cross section, wherein a disk-shaped surface 310 for cylinder head-side contact with the abutment surface ( Figure 1a: 103) of the damping element and an annular portion 312 for abutment against the outside surface ( Figure 1a: 105) of the damping element are formed.
- damping element 102 made of a highly elastomeric material of the annular portion 312 of the outer ring 306 limits the transverse expansion of the damping element 102 in the outer direction, so that the rigidity of the seal assembly in the axial direction and the positional accuracy of the injection point is increased in the combustion chamber.
- Both the inner ring 204 and the outer ring 306 are presently made of stainless steel and are stamped and bent from sheet metal.
- the composite of inner ring 204 and damping element 102 and outer ring 306 is non-positively and positively joined using the spring action of the wire mesh (102).
- a connection can be made by means of spot welding or adhesive.
- Figure 4 shows a section of an internal combustion engine not shown here with a crankcase, a cylinder head 426 and an enclosed by this combustion chamber 428.
- the cylinder head 426 of the internal combustion engine has a opening into the combustion chamber 428 dome 432, in which an injector 422 is added ,
- the injector 422 includes a port 424 for fuel supply and a projecting into the combustion chamber 428 nozzle 430.
- a damping device 400 is arranged at the contact point between the cylinder head 426 and injector 422 in the region of the injector 420. With the arrangement shown, the intermittent fuel injection during operation of the fuel engine vibration generated - even with increased fuel pressure, as prevail in direct injection systems in gasoline and diesel engines - effectively damped.
- the damping device according to the invention makes it possible to comply with very small dimensional tolerances, which could hitherto only with extremely thin decoupling elements, which have a correspondingly low damping effect.
- the damping device achieves both vibration damping and vibration decoupling.
