Definitions

  • the invention relates to an air filter for internal combustion engine according to the features of Preamble of claim 1.
  • an air filter for an internal combustion engine in which in the air filter housing an insert made of an air-permeable and fine-meshed textured fabric or a thin-walled sound element in the air filter housing covered opening covers. This can over the protected housing opening to Generating attractive exterior and interior noise on the vehicle Sound components off be emitted to the intake system.
  • the object of the invention is even better at the effect of the sound device to adapt to the respective operating state of the internal combustion engine.
  • the resonator volume which can be switched on or off by the resonator is advantageous and way integrated in the clean air bowl and is about a pipe section with a pipeline leading to the intake tract of the internal combustion engine, wherein in the pipe section a resonator volume on or off switchable Control is arranged.
  • the controlling body is for example as formed vacuum-controlled flap element. Other embodiments of the Control body, such.
  • the Resonatorvolumen controlling valves or membranes are also possible.
  • tissue or the sound element is accommodated in a frame, which as Insert is secured in the housing opening introduced in the air filter housing.
  • the resonator is disabled in the lower and middle speed range to the excitation of the higher engine orders for sound transmission with a discrete Frequency in the interior to use.
  • the resonator active to lower the interior noise level, as in this area Resonance phenomena by the dominant gas exchange orders particularly strong emerge.
  • the air filter housing 2 shown schematically in Fig. 1 consists of a Rohluftschale 4 and a clean air tray 6, both of which are tightly interconnected.
  • an air filter 8 is arranged between these two shells 4 and 6, between these two shells 4 and 6, an air filter 8 is arranged.
  • the feeder of unfiltered air LR in the housing 2 via a with the raw air space 4a in conjunction standing supply line 10 and then via the air filter 8 in the clean air space 6a and from there from the clean air LM via a supply line 12 to the intake of the Internal combustion engine supplied.
  • an opening 13 is introduced into which a with a fabric structure provided insert member 14 is attached.
  • the frame-like Insert 14 has a plurality of window-like openings 14a to 14e, of the technical tissue are covered.
  • the technical fabric can be used on the Insert 14 sprayed on, welded, glued or clamped to the frame of Insert 14 to be attached.
  • the insert 14 in turn can by means of a screw or Clip connection 16 to be attached to the clean air tray 4.
  • the fabric ensures that by the swinging of the air column in the intake tract of the internal combustion engine On the other hand, it prevents sound components from being conducted to the outside Water, dirt or the like. From the outside via the opening 13 in the air filter housing. 2 can get.
  • the tissue can optionally additionally be coated hydrophobic.
  • the housing opening 13 through a thin-walled sound element is covered, the same or similar characteristics as having the tissue.
  • the fabric or the sound element can oscillate in the process Insert 14 to be attached.
  • a resonator 18 is integrated, the volume 20 via a pipe section 22 with the intake tract of the internal combustion engine leading supply line 12 is in communication.
  • a Shut-off 24 arranged in the present embodiment as a flap formed and in its open position the resonator 20 with the Feed line 12 connects and in the closed state, the resonator 20 of the supply line 12 and thus separated from the intake of the engine.
  • the flap member 24 via a linkage 26 with a Vacuum box 28 connected.
  • the vacuum unit 28 is connected via a pressure line 30 with a vacuum accumulator, not shown, connected by a in the Pressure line 30 arranged switching valve 32, the connection between the pressure box 28th and vacuum reservoir is switched on or off.
  • the resonator volume 20 is in the lower and middle speed range by closing the flap 24 separated from the intake of the engine to the excitation of the higher engine orders for sound transmission at a discrete frequency in the Interior to use.
  • the flap 24 is opened and thus the resonator activates to the outgoing sound or sound level lower in this speed range due to resonance phenomena, stimulated by the dominant gas exchange regulations, especially in the intake system is highly trained.
