Definitions

  • the invention relates to an intake system, in particular for use as an intake passage of an internal combustion engine, according to the preamble of claim 1 (see US-A-444 9607 or US-A-3712416).
  • Intake systems for internal combustion engines are provided in particular in the region of the intake manifold with shunt resonators in order to achieve a damping of the intake noise.
  • these shunt resonators consist of a resonator chamber and a resonator neck which connects the resonator chamber to the suction tube.
  • This basic form of shunt resonator can be varied depending on the particular application. There are several necks conceivable that allow for different lengths attenuation of intake noise of different frequencies.
  • the resonator space can have almost any shape.
  • the resonator space described above must be considered structurally already in the design of the intake manifold.
  • the disadvantage here is that the resonator described can not be used subsequently to improve the acoustics of a suction tube, if the results are unsatisfactory with respect to the intake noise of the intake manifold. In such a situation, there is often no additional space for a shunt resonator even in the engine compartment since the development of the vehicle in question is almost completed. This can be necessary expensive new construction in Saugrohr Anlagen.
  • the object of the invention is to provide a Helmholzresonator claimed a small space for themselves and can also be added later in an existing Saugrohrkonstrutation. In this case, either special frequencies of the intake noise to be damped or broadband attenuation can be achieved.
  • an inner structure is inserted into the interior of the suction tube and fastened there.
  • This internal structure together with the walls of the suction pipe, forms a resonator space which must have at least one opening to the intake manifold volume.
  • Such an internal structure requires no additional space in the engine compartment.
  • a further advantage is the possibility of retrofitting. This is especially easy to implement with suction tubes, which are manufactured in multi-shell technology.
  • such an internal structure can be introduced through the inlet or outlet openings of the suction tube.
  • the shape of the suction tube does not have to be changed at all or only insignificantly.
  • the internal structure z. B. glued, it must be adapted only to a certain contour region of the suction tube.
  • the inner structure may be designed such that it generates a plurality of resonator chambers of different volume after mounting in the intake manifold. By this measure, different frequencies in the intake can be mainly attenuated.
  • a useful variant of the invention provides for the assembly of the inner structure in the interior of the suction tube. This is arranged in front of the intake ducts to the cylinders. Therefore, the noise damping acts on all intake ports of the intake manifold.
  • An alternative variant of the internal structure provides for their design as an insert. This can be carried out in one piece with a positive effect on the economy in mass production.
  • the inner structure may have regions of different wall thickness. If one sees several openings in an inner structure, this results in different neck lengths for the shunt resonator.
  • the positive effect of this measure is a broadband attenuation of the intake noise.
  • the inner structure can also be welded into the intake manifold. This is especially true for plastic suction, but is also conceivable for metallic suction pipes.
  • a plastic entry part can in particular be joined by the ultrasonic welding process. However, there are other welding methods, eg. As the friction welding, possible.
  • a suction pipe 10 is shown in section through one of the intake ports 11.
  • the combustion air is supplied to a plenum 12 through an inlet, not shown.
  • the collecting space distributes the combustion air to the intake ducts 11, which are connected by outlets 13 with not shown cylinder-side air inlets. Through this, the combustion air is supplied to the engine: dead spaces 14 formed in the intake manifold can be used for damping the intake noise.
  • the suction tube consists of several shells 15. Before the shells are welded together, internal structures 16 can be brought into contact with inner walls 17 of the suction tube.
  • the internal structures have bores 18, which serve as necks for the resonator spaces formed by the internal structures.
  • the inner structures can preferably be mounted in the collecting space 12 of the suction tube.
  • the inner structures 16 may consist of a perforated plate 19 and spacers 20 which are mounted between the inner wall 17 and plate 19, consist.
  • the inner structure may consist of a single insert part 21, which is preferably welded to the inner wall 17.
  • welding shoulders 22 must be provided on the inner wall. The welding of the shells 15 takes place after introduction of the inner structures 16.
  • the collection space 12 is shown in longitudinal section. It represents the connection of an inlet 24 for the combustion air and the Saugkanalmünditch 25.
  • the inner structure 16 is shown in plan view. In this illustration, the comparatively large surface area in relation to the height of the inner structure (see FIG. 1) becomes clear. This geometry is necessary because the cross-section of the collecting space must not be excessively narrowed. In this way, a sufficient air supply of the intake ducts is given.
  • FIG. 3 shows a section through the wall section of an inner structure 16.
  • the wall thickness of the component increases linearly in this case.
  • the holes 18, which are introduced at regular intervals in the wall and serve as necks for the shunt resonator, have a different length. As a result, the shunt resonator exhibits a broadband effect.
  • FIG. 4 schematically shows an inner structure 16 with a plurality of resonator cavities 23. These cavities are formed by a dividing wall 26 which rests on the inner wall 17 of the Suction tube supported.
  • the inner structure can be glued via a circumferential lip 27 with the suction tube wall.

Abstract

L'invention concerne un tuyau d'aspiration à niveau sonore optimisé, notamment un tuyau d'aspiration s'utilisant comme canal d'aspiration d'un moteur à combustion interne. L'optimisation du niveau sonore résulte de l'utilisation de résonateurs en dérivation (16, 18) prévus dans l'espace collecteur (12) du tuyau d'aspiration. Ce dernier est produit selon la technique des coques multiples. Avant d'assembler les coques (15), les structures d'insertion (16, 18) sont collées ou soudées. Les résonateurs en dérivation requièrent un encombrement réduit et s'utilisent également pour optimiser ultérieurement des tuyaux d'aspiration dans la phase d'essai, lorsque ceux-ci ne fournissent pas les résultats escomptés en termes d'acoustique.
