Definitions

  • the invention relates to an inlet member for an internal combustion engine according to the Preamble of claim 1.
  • Products with acoustically perceptible sound radiation are then assessed favorably, when their sound effect is pleasant for human hearing. This is especially true for passenger cars that are driven by internal combustion engines, their occupants, namely driver the sound build-up induced by the internal combustion engine attach particular importance.
  • the goodness of the sound structure one Internal combustion engine is quality relevant and by using the knowledge of the technical specialty noise, vibration, roughness - noise, vibration, harshness (NVH) - can be optimized.
  • a known inlet member DE 30 11 294 C2 comprises a housing with a Air intake pipe and a line connected to a suction pipe.
  • the housing has Walls that delimit a chamber through which intake air flows.
  • the object of the invention is to take such precautions on the inlet member, so that the sound structure it induces is beneficial for human hearing.
  • the main advantages achieved with the invention are the fact that the Inlet member through the thin-walled attached to the wall of the housing Radiates defined frequencies, which are based on the theory of harmony in have a certain relationship and a targeted and beneficial one have a psychoacoustic effect on human hearing.
  • the surfaces can be done with reasonable effort Integrate housing. A particularly advantageous function is achieved if the Surfaces are attached to the walls of a container of a suction system. Finally can be targeted with the mass parts attached to the surfaces Frequency radiation can be optimized.
  • An internal combustion engine not shown, includes an inlet member 1, which in the Embodiment is formed by a suction system 2; an air filter also falls under the genus inlet organ.
  • the suction system 2 has an air inlet at 3, which opens into a container 4.
  • a throttle body (not shown) is connected upstream of the air inlet.
  • the container 4 comprises walls 5, 6 which delimit an interior space 7. At the Operation of the internal combustion engine, the interior 7 is flowed through with intake air.
  • Manufactured suction system 2 is for installation in a series internal combustion engine trained, but there is also the possibility of appropriate adaptation to adapt to other types of internal combustion engines.
  • the walls 5, 6 are relatively thin-walled in the manner of a membrane Surfaces 12, 13; 14, 15; 16, 17; 18, 19 provided that are thinner than that remaining area of the walls 5, 6 i.e. outside of these areas, what with Fd (Surface thickness) ⁇ Wd (wall thickness) is expressed.
  • the surface is 12 in Figure 2 shown, being on an inside 20 with a plate-like trained mass part 21 is provided, which only in the area of the surface 12 is provided and is held in position by suitable measures.
  • the surfaces 12, 13; 14, 15; 16, 17; 18, 19 can be circular, square or be rectangular; other configurations are also possible, such as elliptical, polygonal or the like.
  • the areas can be of different sizes, for example, area 18> area 19. The shape, size, and location of these areas can be determined mathematically or iteratively to each other.
  • the surfaces 12, 13; 14, 15; 16, 17, 18, 19 are in the area of the feed lines 8, 9, 10, 12 are provided, which are spaced apart and at 22 with Pipe socket for injection nozzles are provided. At least the surfaces 14, 15 seen in the longitudinal direction C-C of the container 4 on an area dimension Fm, the wider is the cross-sectional dimension Qm of the corresponding supply line e.g. 10th
  • the surface 12 is reduced by a local cross-sectional taper Qv formed, the thickness of which is less than the thickness Wd of the wall 5. Finally, at 23 the transition between Wd and Qv is indicated.
