Definitions

  • the present invention relates to a device for exhaust gas treatment according to the preamble of claim 1.
  • Exhaust gas treatment devices intended to be arranged in an exhaust system of a combustion engine are previously known in a multiplicity of different forms.
  • Such an exhaust gas treatment device usually comprises a casing with an inlet aperture for receiving exhaust gases and an outlet aperture for exhaust gases, and a passage extending inside the casing to guide the exhaust gases between the inlet aperture and the outlet aperture.
  • the exhaust gases are brought into contact with means arranged inside the casing for damping of the low-frequency noise caused by the exhaust gases, and/or means for cleaning of the exhaust gases, e.g. one or more catalysts for effecting catalytic conversion of environmentally dangerous components of the exhaust gases to environmentally less dangerous substances, and/or one or more particle filters for removing particulate components from the exhaust gases.
  • An exhaust gas treatment device is previously known, e.g. from SE 520 350 C2.
  • That exhaust gas treatment device comprises a substantially cylindrical casing with an inlet aperture arranged in the shell surface of the casing and an outlet aperture arranged in an endwall of the casing.
  • the inside of the casing is provided with means for noise damping and means for cleaning the exhaust gases.
  • That exhaust gas treatment device is thus designed to effect both noise damping and exhaust gas cleaning.
  • An exhaust gas treatment device is also previously known from GB 2 212 771 A.
  • That exhaust gas treatment device comprises a cylindrical casing with an inlet aperture and an outlet aperture arranged in the shell surface of the casing.
  • the inside of the casing is provided with means for noise damping.
  • That exhaust gas treatment device thus constitutes a silencer.
  • the casing is fastened in a retainer which allows rotation of the casing relative to the combustion engine at the time of fitting the casing to the combustion engine.
  • an exhaust gas treatment device of the type concerned to a heavy motor vehicle e.g. in the form of a truck or trailer
  • the exhaust gas treatment device being placed with the longitudinal axis of the casing extending substantially parallel with or substantially perpendicular to the longitudinal axis of the motor vehicle.
  • the exhaust gases from the motor vehicle's combustion engine are released into the open air downwards under the motor vehicle, to the right of the motor vehicle, to the left of the motor vehicle or vertically upwards.
  • the exhaust line between the exhaust gas treatment device and the exhaust system outlet has therefore to be routed differently depending on the desired location and direction of the exhaust system outlet.
  • the object of the present invention is to provide an exhaust gas treatment device of the type indicated in the introduction which affords greater flexibility in the design and fitting of an associated exhaust system and simplifies the adaptation of the exhaust system to the desired location and direction of the exhaust system outlet.
  • the device comprises a pipe connection which has an outlet aperture and an inlet aperture which is connected or connectable to the outlet aperture of the casing, which pipe connection is fastened or fastenable to the casing and settable at different rotational positions relative to the casing in order to regulate the direction of the outlet aperture of the pipe connection relative to the casing.
  • the direction of the outlet of the exhaust gas treatment device can thus be varied without altering the location or orientation of the casing, thereby making it particularly easy to give the outlet of the exhaust gas treatment device a direction which is favourable with regard to the desired location and direction of the exhaust system outlet.
  • the possibility of varying the direction of the outlet of the exhaust gas treatment device according to the invention makes it possible in many cases to make the exhaust line between the exhaust gas treatment device and exhaust system outlet straighter and occupy less space than would be possible when using a conventional design of exhaust gas treatment device with a fixed outlet direction.
  • a straighter and shorter exhaust line is less expensive to manufacture and fit and at the same time reduces the risk of damage to the exhaust line.
  • the pipe connection comprises a contact surface intended to engage with a corresponding contact surface of the casing or of a component arranged in the casing, said contact surfaces being so designed that the pipe connection is rotatable relative to the casing when the contact surfaces are in mutual engagement.
  • the device 1 is intended to be arranged in an exhaust system of a combustion engine in order to effect damping of the low-frequency noise caused by the exhaust gases and/or to effect cleaning of the exhaust gases.
  • the device comprises a casing 2 with an inlet aperture 3 for receiving exhaust gases arising from the combustion engine, and an outlet aperture 4 for departure of exhaust gases after they have passed through the casing.
  • a passage 5 is arranged for guiding the exhaust gases between the inlet aperture 3 and the outlet aperture 4.
  • the passage 5 extending between the inlet aperture 3 and the outlet aperture 4 is provided inside with means 6 for damping of noise caused by the exhaust gases, and/or means 7 for cleaning the exhaust gases.
  • These latter means 7 may comprise one or more catalysts for effecting catalyst conversion of environmentally dangerous components of the exhaust gases to environmentally less dangerous substances, and/or one or more particle filters for removing particulate components from the exhaust gases.
  • the casing 2 constitutes a closed external surface except at the points where the inlet aperture 3 and the outlet aperture 4 are arranged.
  • the device 1 comprises a pipe connection 8 which has an outlet aperture 10 and an inlet aperture 9 which is connected or connectable to the outlet aperture 4 of the casing.
  • the pipe connection 8 is fastened or fastenable to the casing 2 and settable at various rotational positions relative to the casing 2 in order to regulate the direction of the outlet aperture 10 of the pipe connection relative to the casing 2.
  • the pipe connection 8 has a contact surface 11 intended to engage with a corresponding contact surface 12 of the casing 2 (see Fig. 6) or of a component 13 arranged in the casing (see Fig. 4), said contact surfaces 11, 12 being designed to enable the pipe connection 12 to be rotated relative to the casing 2 when the contact surfaces 11, 12 are in mutual engagement.
  • Said contact surfaces 11, 12 are preferably rotationally symmetrical.
  • the pipe connection 8 may be steplessly rotatable relative to the casing 2 or alternatively be rotatable between various predetermined setting positions relative to the casing.
  • the pipe connection 8 and the casing 2 have mutually engaging portions 14 of polygonal cross-sectional shape, e.g.
  • a square cross-sectional shape of the engaging portions 14 concerned provides four different rotational positions of the pipe connection 8 relative to the casing 2.
  • changing the rotational position of the pipe connection relative to the casing involves the pipe connection 8 being removed from the casing 2 and being returned to engagement with the casing after being rotated relative to the casing 2.
  • the pipe connection 8 is with advantage clamped firmly to the casing 2 by a clamping means 15.
  • the clamping means 15 preferably takes the form of a clamp ring, advantageously of V-shaped or U-shaped cross-section, arranged to engage with the pipe connection 8 externally about a flange 16 extending round the pipe connection's inlet aperture 9.
  • the pipe connection's flange 16 is arranged to engage via its outside with the clamp ring 15 and via its inside with a corresponding flange 17', 17 of the casing 2 (see Fig. 6) or of a component 13 arranged in the casing 2 (see Fig. 4).
  • the aforesaid contact surface 11 of the pipe connection is thus arranged on the inside of the pipe connection's flange, while the corresponding contact surface 12 of the casing/component is arranged on the outside of the flange 17', 17 of the casing/component.
  • the device 1 comprises a component 13 in the form of an exhaust gas cleaning unit fitted detachably inside the casing 2 and insertable in the casing 2 via the casing's outlet aperture 4.
  • the clamping means 15 is with advantage arranged to clamp the pipe connection 8 firmly to the casing 2 by firmly clamping a flange 16 of the pipe connection and a flange 20 of the casing to a corresponding flange 17 of the exhaust gas cleaning unit 13.
  • the clamping means 15 has two mutually opposite flanges 21, 22, whereby the one flange 21 engages externally about the pipe connection's flange 16 and the other flange 22 engages externally about the casing's flange 20 and clamps these flanges 16, 20 firmly to the exhaust gas cleaning unit's flange 17 situated under them. It thus becomes possible to use a single clamping means 15 to clamp both the pipe connection 8 and the exhaust gas cleaning unit 13 firmly to the casing 2.
  • the exhaust gas cleaning unit 13 comprises preferably a catalyst but might also comprise a particle filter or a catalyst in combination with a particle filter.
  • the casing 2 is substantially cylindrical and the casing's outlet aperture 4 is arranged in an endwall 23a of the casing, whereby the pipe connection 8 when fastened to the casing is arranged to protrude from this endwall.
  • the pipe connection's inlet aperture 9 has a centreline which substantially coincides with or is substantially parallel with the casing's centreline 24a.
  • the pipe connection's outlet aperture 10 is arranged to be directed away from the casing's centreline 24a when the pipe connection is fastened to the casing.
  • the pipe connection's outlet aperture 10 thus has a centreline 24b which extends at an angle relative to the casing's centreline 24a when the pipe connection is fastened to the casing.
  • the centreline 24b of the pipe connection's outlet aperture 10 consequently extends likewise at an angle relative to the centreline of the pipe connection's inlet aperture 9.
  • the casing's inlet aperture 3 is with advantage arranged in the casing's shell surface 25. If advantageous, elements 26 made of thermally insulating material may be arranged on the outside of the casing, as illustrated in Fig. 3.
  • a cylindrical pipe 27 is arranged inside the casing 2 in such a way that the pipe's centreline substantially coincides with the casing's centreline 24a.
  • This pipe 27 extends from the endwall 23a provided with the outlet aperture 4 to a module 28 which comprises a second endwall 23b of the casing 2.
  • the module 28 is advantageously fastened detachably to the remainder of casing 2 by a clamping means 29 in the form of a clamp ring.
  • the aforesaid exhaust gas cleaning unit 13 is fitted inside the pipe 27.
  • the passage 5 between the casing's inlet aperture and outlet aperture comprises a first part-section 5a situated between the casing 2 and the pipe 27, i.e. externally about the pipe 27.
  • the first part-section 5a is connected by a second part-section 5b situated in the module 28 to a third part-section 5c situated internally in the pipe 27.
  • the casing's inlet aperture 3 is connected to the first part-section 5a and the casing's outlet aperture 4 is connected to the third part-section 5c so that the exhaust gases received by the device are caused to flow successively through the first part-section 5a, the second part-section 5b and the third part-section 5c.
  • the greater part of the noise caused by the exhaust gases from a combustion engine comprises low-frequency noise.
  • a basic principle for damping low-frequency noise arising from exhaust gases is to lead the exhaust gases through a long line between two spaces.
  • the device 1 illustrated comprises noise-damping means 6 constructed according to this principle. Between a first space constituted by the passage's first part-section 5a and a second space constituted by the passage's third part-section 5c, the exhaust gases are led in a spiral flowpath 30 into the passage's second part-section 5b, as illustrated in Figs. 3 and 5. This spiral flowpath leads the exhaust gases radially inwards towards the casing's centreline 24a from the first part-section 5a to the third part-section 5c.
  • a particle filter (not depicted) may be arranged in the first part-section 5a of the passage 5, i.e. in the space between the pipe 27 and the casing 2.
  • the device 1 according to the invention is particularly intended to be fitted to a heavy motor vehicle, e.g. in the form of a truck or trailer, in order to treat exhaust gases from the motor vehicle's combustion engine.
  • the device 1 is normally positioned with the longitudinal axis of the casing extending substantially parallel with or substantially perpendicular to the motor vehicle's longitudinal axis.
  • Figs. 8 and 9 illustrate a device 1 according to the present invention, fitted to a member 40 forming part of the frame of a motor vehicle.
  • the member 40 illustrated is conceived as extending in the longitudinal direction of the motor vehicle.
  • FIG. 8 illustrates how the device 1 is suspended by means of a bracket relative to the member 40 concerned, with the longitudinal axis of the casing 2 extending substantially perpendicular to the longitudinal direction of the member, i.e. substantially perpendicular to the longitudinal axis of the motor vehicle.
  • Fig. 9 illustrates how the device 1 is suspended by means of a bracket 42 relative to the member 40 concerned, with the longitudinal axis of the casing 2 extending substantially parallel with the longitudinal direction of the member, i.e. substantially parallel with the longitudinal axis of the motor vehicle.
  • the passage 5 and the noise-damping means 6 may be designed differently from what is here illustrated.
  • the design of the casing 2 may also be different both internally and externally from what is here illustrated.
