Definitions

  • the invention relates to an air filter for an internal combustion engine according to the preamble of claim 1.
  • an air filter for an internal combustion engine in a vehicle for the transmission of sound in the vehicle interior for which purpose a housing opening is provided by a vibrating and airtight membrane in the air filter housing. This has a sound-softening material than the housing wall, so that a targeted Schallerzeugung- and spread is made by the shape and position of the membrane.
  • an air filter for an internal combustion engine with a housing is known, which has in the region of the unfiltered air intake a lower bottom with an opening which is closed by a porous material, whereby input noise is to be reduced.
  • the object of the invention is to design an air filter housing in such a way that an external and internal noise of vehicles is to be influenced acoustically and in the air filter housing in a simple manner of mounting a sound device is to be integrated.
  • the invention advantageously achieves that sound components in the intake tract are emitted via the openings in the air filter housing covered by a fabric or a thin-walled sound element in such a way that an attractive exterior and interior noise is produced on the vehicle.
  • This is essentially achieved by providing at least one perforations exhibiting end of the airborne radiation in the unfiltered air or clean air shell of the air filter housing, which is held inserted in a housing opening and an air-permeable and fine mesh structured fabric or the thin-walled Sound element is completed.
  • the fabric may be water-repellent or waterproof.
  • the perforations are provided in an insert part which is inserted into the housing opening.
  • the fabric or the sound element can also be clamped between two perforated inserts in the housing opening and the housing opening is closed air permeable. Furthermore, a design is conceivable in which the perforations are injected into the housing wall and these are then covered by the fabric or the sound element.
  • stop dampers can be provided on the insert parts.
  • the fabric may also be adhered to the perforation.
  • the fabric used is a so-called technical fabric, which can be sealed against water, rain and dirt, etc.
  • this fabric is fine mesh designed such that a disadvantageous intake of hot air from the engine compartment is avoided, for example, during warm starts.
  • the tissue in the range of small air flow rates, such as at start, idle and at partial load of the internal combustion engine only a small flow to.
  • the tissue may allow a larger proportion of the intake air due to its structuring. This leads to a reduction of the pressure behavior in the intake system and can be used to increase the performance of the engine. Due to the different air intake in the various operating conditions of the engine, a desired hot / cold separation with respect to the intake air is possible.
  • a wall having perforations is formed on the housing wall forming the housing opening, and the membrane consisting of the fabric or the thin-walled sound element is arranged between this wall and an insert part fitted with perforations.
  • the membrane consisting of the fabric or the sound element can be connected to a frame which is arranged above or below a housing opening and connected to the housing.
  • An air filter housing 1 for an internal combustion engine of a motor vehicle is composed at least of a raw air shell 2 and a clean air shell 3, which are sealed together. Between these two shells 2 and 3, an air filter 4 is arranged. The supply of unfiltered air LR in the housing 1 via a Snorkel 20 or via an opening 5 in the Roh Kunststoffschale 2 and then through the air filter 4 in the clean air bowl 3 and from here, the clean air LM is fed via a feed line to a motor.
  • an air opening 6 is provided, for example, the top of the housing or at another location of the housing having perforations 7.
  • the opening is shown by way of example only in the Roh Kunststoffschale 2; It can also be provided in the clean air bowl 3.
  • These perforations 7 are covered to the outside with a technical fabric 8, which is executed fine-mesh structured and against water, dirt, rain and the like. Seals.
  • a thin-walled sound element which has the same properties as a tissue.
  • air can be sucked from the outside and sound components are radiated in the intake via the housing such that an external and internal noise is tuned.
  • the fabric or the sound element can be arranged swinging.
  • the opening 6 in the Rohluftschale 2 of the housing 1 is provided with perforations in an insert part 11 which is provided with holes of a certain number, shape and diameter, which are covered by the technical fabric 8 or the sound element.
  • the insert 11 may either have been molded or sprayed into the housing wall or it is a fastenable separate part.
  • the Roh Kunststoffschale 2 is in the Roh Kunststoffschale 2 between two provided with perforations 7 inserts 10 and 11, the technical fabric 8 or the sound element arranged.
  • stop damper 12, 13 With the inserts 10 and 11 inside mutually directed stop damper 12, 13 are connected, which are spaced apart or adjacent and between which the technical fabric 8 or the sound element is arranged.
  • These stop dampers 12, 13 are preferably made of a damping material such as for example, foam, so that in case of possible pressure jumps no unwanted noise, such as so-called. "Ploppge Hursche" may arise.
  • the technical fabric 8 or the sound element may have such a structure that in the range of small air flow rates, such as at start, idle and at partial load of the engine only a small air flow is allowed; however, in the area of larger air flow rates, such as at full load, a larger proportion of the intake air is allowed.
  • the formation of the raw air shell 2 with the air opening 6 a certain acoustics is achieved by sound radiation to optimize the exterior and interior noise of the vehicle.
  • the Roh Kunststoffschale 2 may be provided with the so-called air snorkel 20 by instead of or in combination with the air opening 6, an opening 6a is provided with perforations. This is then covered accordingly with the technical fabric 8 or the sound element, so that a sound radiation from this location is also possible. Furthermore, the opening 6 can also be arranged laterally or at another location of the raw air or clean air tray 2 or 3. There may be a perforation 7 having opening 6 with a tissue or sound element cover for airborne sound radiation at least in a region of an air duct from the snorkel 20 to the throttle valve of the engine.
  • the perforations 7 may also be injected into the housing wall of the Roh Kunststoffschale 2 and then 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 be arranged in any area of the air duct to the engine.
  • the technical fabric 8 or the equivalent sound element is attached to a frame 14, which is connected to the Roh Kunststoffschale 2 of the housing 1 and covers the air opening 6 in the housing 1.
  • This frame 14 may also cover an opening in the clean air tray 3.
  • the opening 6 in the Rohluftschale 2 is connected by a provided with perforations 7 housing wall 15, to which a channel 16 connects, which is closed by the fabric 8 or the sound element.
