Definitions

  • the present invention relates to an exhaust device on motor vehicles with an arrangement of pipes enclosed by a housing, the end regions of the pipes protruding diametrically from the housing in such a way that one pipe end is connected to the engine and at least one further pipe end protrudes from the side of the housing facing away from the motor.
  • the present invention is based on the object of proposing an exhaust device which has suitable means for sound insulation on the one hand and for cleaning on the other hand, and prevents direct pollution of the ambient air.
  • an economical and structurally simple design should be possible.
  • the object is achieved according to the invention in that the pipe end (7a, 8a) is closed and has openings (9) in the pipe jacket wall at least in the area (7b, 8b) projecting from the housing (2), and in that ( 1) gas-permeable means for cleaning and soundproofing are arranged which at least partially surround the pipe arrangement.
  • FIG. 1 An exhaust device is shown, partly in section, in FIG.
  • a housing 2 encloses a pipe arrangement which is connected to the motor (not shown) by means of the pipe 3.
  • the housing 2 has a jacket wall 4. This can also consist of two parts, which are then welded or flanged together.
  • the housing is closed at both ends by means of a wall 5 and 6, respectively, with openings in the wall for the pipe passages.
  • Pipe parts 7 and 8 are welded to pipe 3 in the housing, which form a branch and in turn are composed of several parts.
  • the end region 7a or 8a of the two tubes is closed at their respective ends and has openings 9 directed towards the carriageway. These openings serve as an outlet for the gases emerging from the engine. They can be arranged in parallel rows or offset.
  • the openings are preferably circular. Experiments have shown that optimal results were achieved with eight openings. The diameter of the openings can be varied.
  • a further wall 10 or 6a is arranged parallel to the wall 6 of the container 2.
  • a filter arrangement is provided between these two walls and is used to clean the exhaust gas emerging.
  • glass wool can also be arranged.
  • the filter arrangement can have ceramic parts and / or metal chips.
  • the inner wall 4 of the housing 2 has a lining 4a, which is provided as a silencer. This lining can be made of glass wool or some other suitable material.
  • REPLACEMENT LEAF ' OMPI Another variant of the described exhaust device is that the pipe run from the engine through the tank is not continuous.
  • a chamber is formed by the container wall and a wall 6a spaced from it.
  • the wall 6a is preferably perforated in order to promote the circulation of the gases.
  • the pipe ends are "held in the respective wall by means of a welded construction.

Abstract

Dispositif d'échappement dans lequel les gaz d'échappement sortant du moteur ne sont pas évacués directement dans l'air ambiant. L'extrémité libre du tuyau d'échappement est fermée et des ouvertures sont pratiquées dans l'enveloppe du tuyau dans la région de l'extrémité libre. Les ouvertures sont dirigées du côté de la chaussée. Des filtres supplémentaires sont situés dans le récipient pour purifier les gaz d'échappement. Le récipient est doté d'un revêtement le long de la surface de son enveloppe pour améliorer l'insonorisation. La construction simple du dispositif d'échappement proposé rend sa fabrication économique. En outre, sa contribution à la protection de l'environnement est considérable.
