Definitions

  • the present invention relates to a silencer for an at least partially twin-flow exhaust system of an internal combustion engine, in particular of a motor vehicle.
  • the invention also relates to an exhaust system equipped with such a silencer.
  • the exhaust gas generated by the internal combustion engine is discharged via two separate floods.
  • a double-flow design can be useful, for example, in V-engines or boxer engines.
  • the two strands of the twin-flow exhaust system can be assigned to common silencer, for example.
  • Such a silencer in this case comprises a housing which encloses an interior space, and two exhaust pipes through which exhaust gas can flow in parallel and which are respectively led through the interior of the housing.
  • a silencer can be designed as a Helmholtz resonator. The interior of the housing then serves as a resonance volume.
  • a T-shaped neck body may be provided, which is communicatively connected via a cross tube to the two exhaust pipes and from which an extending between the exhaust pipes extending tube, which is open to the interior of the housing.
  • a cross tube to the two exhaust pipes and from which an extending between the exhaust pipes extending tube, which is open to the interior of the housing.
  • EP1959106A1 discloses a conventional muffler with a Helmholtz resonator.
  • the present invention is concerned with the problem of providing for a muffler of the type mentioned or for an exhaust system equipped therewith with an improved embodiment, which is characterized in particular by the fact that the muffler is comparatively compact and comparatively inexpensive to produce, at the same time a sufficient Damping effect should be feasible.
  • the invention is based on the general idea to form the neck body by means of two sheet-shaped longitudinal walls, which are spaced apart and abut respectively on both exhaust pipes. Between these longitudinal walls, a neck volume is limited, which is open on the one hand to the resonant volume, ie to the interior of the housing and in the other side side openings of the exhaust pipes open.
  • the neck body receives an extremely easy to implement structure that can be produced inexpensively and also comparatively easy gas-tight connect with the exhaust pipes. For example, only straight welds are required, which are relatively easy to produce with high quality.
  • the neck body between the two exhaust pipes requires little installation space, since the two longitudinal walls are supported directly on the exhaust pipes, so that lying between the two longitudinal walls wall portions of the exhaust pipes form lateral boundaries of the neck volume and thus contribute to the realization of the neck body.
  • the proposed neck body comes with a comparatively small distance between the exhaust pipes to a sufficient neck volume for to realize the desired Helmholtz resonator. Accordingly, the proposed muffler can build comparatively compact.
  • the neck body may also have a sheet-like transverse wall which limits the neck volume on the one hand of the side openings, so that the neck volume only on the other hand, the side openings to the resonance volume is open. Due to this construction, the formed Helmholtz resonator has only a single neck volume, whereby it can be designed specifically for a specific resonance frequency.
  • the neck body is formed by a U-shaped sheet metal part, whose legs form the longitudinal walls and whose two legs connecting base forms the transverse wall.
  • this sheet metal part may be formed in particular from a single piece of sheet metal.
  • Fig. 1 to 8 comprises a muffler 1, which can be used in a not shown here, at least partially twin-flow exhaust system of an internal combustion engine, which may be arranged in particular in a motor vehicle, a housing 2, the interior 3 encloses.
  • the housing 2 consists, for example, of two frontally arranged bottoms 4 and of two half-shells 5, which surround the interior 3 laterally and in which the bottoms 4 are used for longitudinal limitation of the interior 3.
  • Fig. 1 is the observer facing half-shell 5 omitted to allow insight into the interior 3 of the housing 2.
  • the housing 2 has through the two half-shells 5 and through the two floors 4 an extremely simple and inexpensive construction. In principle, however, other designs for the housing 2 are conceivable.
  • a one-piece tubular body can be used instead of the two half-shells 5.
  • the muffler 1 also has exactly two or at least two exhaust pipes 6, which can be flowed through in parallel by the exhaust gas of the internal combustion engine and which are respectively guided through the inner space 3.
  • the exhaust pipes 6 are guided through the two bottoms 4.
  • the bottoms 4 have for this purpose annular collar 7, in which end portions of the exhaust pipes 6 are inserted.
  • Each exhaust pipe 6 has within the housing 2 in the Fig. 4, 5 and 8th recognizable side opening 8. These side openings 8 are expediently arranged on the two exhaust pipes 6 so that they face each other. In particular, they are aligned with each other.
  • the muffler 1 further includes a neck body 9, which serves to connect the two side openings 8 communicating with the interior 3 of the housing 2, in such a way that in this case a Helmholtz resonator is formed.
  • the interior 3 of the housing 2 then serves as resonance volume of the Helmholtz resonator, while the neck body 9 encloses a neck volume 10 which defines the neck of the Helmholtz resonator.
  • the neck body 9 has two sheet-shaped longitudinal walls 11, each at both exhaust pipes 6 abut.
  • the longitudinal walls 11 are spaced from each other and define the aforementioned neck volume 10.
  • the longitudinal walls 11 are arranged so that the side openings 8 open into the neck volume 10 between them.
  • the two longitudinal walls 11 are open to the interior 3, that is to say to the resonant volume of the Helmholtz resonator designated below by 12.
  • the neck body 9 is disposed entirely within the housing 2, in particular spaced from the housing 2 positioned.
  • the neck body 9 also has a sheet-like transverse wall 13, which likewise forms a boundary of the neck volume 10. Accordingly, the neck volume 10 on the one hand of the side openings 8 is limited by the transverse wall 13 and on the other hand, the side openings 8 to the resonance volume 12 open. As a result, the neck volume 10 can be precisely determined, which simplifies the design of the Helmholtz resonator to a specific resonant frequency.
  • the neck body 9 according to the 6 and 7 produce by means of a U-shaped sheet metal part 14, which may be formed in particular from a single piece of sheet metal.
  • Legs 15 of the U-sheet metal part 14 form the longitudinal walls 11, while the two legs 15 interconnecting base 16 of the U-sheet metal part 14 forms the transverse wall 13.
  • the Helmholtz resonator For the design of the Helmholtz resonator, it has proven to be favorable to arrange the two side openings 8 in the region of the transverse wall 13. As a result, virtually the entire neck volume 10 is available for generating a vibrating air mass.
  • the neck body 9 can also be dispensed with the transverse wall 13, so that the neck volume 10 then on both sides of the side openings 8 to the resonance volume 12 is open.
  • the neck body 9 then has two mutually opposite openings, with which it communicates with the resonance volume 12 and with the interior 3.
  • the side openings 8 are located within the neck volume 10.
  • the Helmholtz resonator acts uniformly for both exhaust pipes 6.
  • the two exhaust pipes 6 are guided in a straight line and parallel to each other through the housing 2.
  • the exhaust pipes 6 in the example between the plates 4 each have a constant cross section, which facilitates in particular the attachment of the neck body 9.
  • other designs are conceivable here as well.
  • the longitudinal walls 11 and the possibly existing transverse wall 13 are each "sheet-shaped" configured. This means in the present context, a substantially flat configuration of the walls, that is, the respective wall is dimensioned considerably larger in the longitudinal direction and in the width direction than in the thickness direction. Furthermore, the longitudinal walls 11 are each configured just here. Further, the investment areas in which the longitudinal walls 11 abut the exhaust pipes 6, designed here in a straight line, which is a gas-tight Connection between the longitudinal walls 11 and the exhaust pipes 6 simplified.
  • the neck body 9 may be welded or soldered to the exhaust pipes 6.
  • the bottoms 4 can be welded or soldered to the half-shells 5. Also, the two half-shells 5 can be attached to each other by welds or solder joints.
  • the exhaust pipes 6 may be soldered or welded at their ends to the collar 7 of the bottom 4.
  • the housing 2 may have a cross-section in the shape of a horizontal figure 8, that is, the half-shells 5 are each concave outwards.
  • the stability of the housing 2 can be increased.
  • this also the vibration behavior of the housing 2 can be influenced in the desired manner.
  • this also allows the resonance volume 12 to be defined for the design of the Helmholtz resonator.
  • the side openings 8 are provided with a circular cross-section. Fits to the transverse wall 13 in longitudinal section, such as in Fig. 7 clearly semicircular design. The radii of the side openings 8 and the transverse wall 3 are suitably coordinated with each other.
