Definitions

  • the invention relates to an air filter for an internal combustion engine according to the Preamble of claim 1.
  • the object of the invention is to design an air filter housing in such a way that a External and internal noise of vehicles is to be influenced acoustically and in that Air filter housing to integrate a sound device in a simple manner.
  • the perforated insert parts with intervening tissue or sound element no impact noises from the fabric or the scarf element during pressure jumps shock absorbers can be provided on the insert parts.
  • the tissue can also be glued to the perforation.
  • the fabric used is a so-called technical fabric, which is opposite Water, rain and dirt etc. can be sealed.
  • this is Fabric finely meshed so that an adverse intake of warm air from the engine compartment, for example during warm starts.
  • Larger air throughputs, such as when the internal combustion engine is at full load can do this
  • tissue makes up a larger proportion of the air drawn in allow. This leads to a reduction in the pressure behavior in the suction system and can be used to increase the performance of the engine.
  • the one forming the housing opening A wall with perforations is molded into the housing wall and between these Wall and a perforated insert is the part of the Fabric or the thin-walled sound element membrane arranged.
  • the membrane consisting of the tissue or the sound element can also be used be connected to a frame above or below a housing opening arranged and connected to the housing.
  • An air filter housing 1 for an internal combustion engine of a motor vehicle sits down at least composed of a raw air shell 2 and a clean air shell 3, which are tight are interconnected.
  • An air filter 4 is located between these two shells 2 and 3 arranged.
  • Raw air LR is fed into the housing 1 via a Snorkel 20 or through an opening 5 in the raw air shell 2 and then through the Air filter 4 in the clean air tray 3 and from here, the clean air LM via a Feed line fed to a motor.
  • Air opening 6 is provided, which has perforations 7.
  • the opening is exemplary only shown in the raw air tray 2; it can also be provided in the clean air tray 3.
  • These perforations 7 are covered on the outside with a technical fabric 8, that is finely meshed and structured against water, dirt, rain and the like. seals.
  • a thin-walled sound element can also be used, which is the has the same properties as a fabric. In contrast, air can come from outside are sucked in and sound components are in the intake tract via the housing emitted that external and internal noise can be tuned. The same applies also for the clean air shell 3.
  • the fabric or the sound element can vibrate be arranged.
  • a first version according to Fig. 1 is the opening 6 in the raw air shell 2 of the Provided housing 1 with perforations in an insert part 11, the holes certain number, shape and diameter provided by the technical Tissue 8 or the sound element are covered.
  • the insert 11 can either in the housing wall may have been molded in or co-injected, or it may be fastened separate part.
  • After another execution acc. 2 is in the raw air tray 2 between two insert parts 10 and 11 provided with perforations 7 the technical Tissue 8 or the sound element arranged.
  • Stop dampers 12, 13 are mutually directed stop dampers 12, 13 connected to each other, which are spaced or abutting and between them the technical fabric 8 or the sound element is arranged.
  • This Stop dampers 12, 13 preferably consist of a damping material such as for example made of foam, so that no pressure jumps unwanted noises, such as so-called "pop sounds" can occur.
  • the technical fabric 8 or the sound element can have such a structure, that in the area of small air flow rates, such as when starting, idling and at partial load of the Motor only a small air flow is allowed; against it in the area Larger air flow rates, such as at full load, become a larger proportion of the air drawn in authorized.
  • the raw air shell 2 can be provided with the so-called air snorkel 20 by instead of or in combination with the air opening 6, an opening 6a with perforations is provided. This is then the technical fabric 8 or the Sound element covered so that sound radiation can also be emitted from this location is possible. Furthermore, the opening 6 can also be on the side or at another location Raw air or clean air tray 2 or 3 can be arranged.
  • the perforations 7 can also be injected into the housing wall of the raw air shell 2 be and then be covered by the fabric 8 or the sound element.
  • the Opening 6 with the perforations 7 and the fabric 8 or the sound element can in any area of the air duct to the engine.
  • the technical fabric is 8 or the equivalent sound element attached to a frame 14 which with the Raw air shell 2 of the housing 1 is connected and the air opening 6 in the housing 1 covers.
  • This frame 14 can also cover an opening in the clean air tray 3.
  • Fig. 4 is the opening 6 in the raw air shell 2 through a housing wall 15 provided with perforations 7, to which a channel 16 connects which is closed by the tissue 8 or the sound element. A Covering to the outside takes place via a shell 17, which also has perforations 7 having.
