Definitions
- the invention relates to a muffler housing and an associated metallic catalyst carrier body for cleaning exhaust gas, in particular small engines.
- the invention further relates to a method for producing a catalyst carrier body.
- Catalyst carrier bodies for cleaning exhaust gas which have holding elements.
- FR 2 444 793 describes a carrier body in which metallic clamping bands are used to fix the position of the packet of the catalyst carrier body.
- the clamping bands are not intended for attachment to an exhaust pipe housing; rather, in the exhaust pipe housing in an additional work step, for which a special additional manufacturing device is required, sections have to be formed circumferentially on the outer circumference of the catalyst carrier body in order to seal the To ensure support body in the exhaust pipe housing.
- DE 38 29 668 describes an exhaust gas silencer for two-stroke engines with a receptacle for a catalyst carrier body, in which the receptacle forms an exhaust gas space through two profiled plates.
- the catalyst carrier body has, in a known manner, a jacket tube on which the plates are appropriately supported and fastened, the plates being attached to the catalyst carrier body provided with jacket tube in such a way that it points away from the support region as a whole, but not penetrates.
- the profiled plates also contain a part of the exhaust pipe, so that the production such complex profiled plates is expensive and does not appear to be particularly suitable, in particular, for catalytic converters of small engines.
- a catalyst carrier body is described in US Pat. No. 4,795,615, in which jacket clamping strips are provided for fixing the position in the exhaust pipe system.
- the jacket clamping strips ensure a positional fixation in the exhaust pipe housing, but the catalyst carrier body must have further devices so that it can be kept dimensionally stable during transport until installation in the exhaust pipe housing.
- EP 0 470 113 describes a catalyst carrier body which has a jacket tube so that it can be transported in a dimensionally stable manner to the installation location in an exhaust gas pipe system, the jacket tube having a circumferential bead to which a holding plate can be fastened.
- This holding plate is used for the further fastening of the unit consisting of holding plate, casing tube and catalyst carrier body in the exhaust pipe housing.
- a catalyst carrier body is described in DE 27 46 475, in which a tension band is placed around a carrier body, the overlapping ends of which are fastened to the inner circumference of the exhaust pipe housing.
- a tensioning strap serves the possibility of being able to transport the carrier body separately to the installation location, a mechanically stable attachment in the exhaust pipe housing, which is also stable against vibrations, is therefore difficult because the tensioning strap should absorb thermal expansions and therefore not in its entirety with the exhaust gas pipe housing can be connected.
- the object of the invention is to create a catalyst carrier body and a method for its production, which can be transported in a dimensionally stable manner, does not require a jacket tube and can be produced inexpensively as well is easily adaptable and usable in an exhaust pipe housing.
- a corresponding muffler housing for installing such catalyst carrier bodies is also to be created.
- the metallic catalyst carrier body according to the invention is used to purify exhaust gas, in particular small engines, and has a longitudinal axis and a multiplicity of flow paths in its interior, the catalyst carrier body being provided for mounting in an exhaust pipe housing.
- the carrier body has a holding element with an opening therein, which in the region of the opening surrounds a part of the lateral surface of the carrier body, in particular essentially encloses an entire circumference, and is fastened directly to the catalyst carrier body, the holding element being fastenable in the exhaust gas line housing and holds the catalyst carrier body dimensionally stable and / or carries substantially alone.
- the holding element with the exhaust pipe housing which has an inflow chamber for the exhaust gas stream to be cleaned and an outflow chamber for the cleaned exhaust gas stream, the two chambers being connected to one another via the catalyst carrier body, in such a way that a first part of the carrier body faces the inflow chamber and a second part of the carrier body of the outflow chamber which is sealed off from it is facing.
- the first and second part of the carrier body are preferably of approximately the same length.
- Corresponding installation conditions of the catalyst carrier body in the exhaust pipe housing, in particular if this is a muffler housing may however require different length distributions.
- the holding element is fastened directly to the carrier body, it serves to directly guarantee the dimensional stability of the catalyst carrier body once it has been produced.
- the holding element is further designed so that it corresponds to the inner shape of the exhaust pipe housing and thus also serves for direct attachment within the exhaust pipe housing.
- This attachment is carried out so that a reliable, essentially sealing subdivision of the exhaust pipe housing into an inflow chamber into which the exhaust gas stream to be cleaned enters, and an outflow chamber into which the cleaned exhaust gas stream enters from the catalyst carrier body.
- radial catalytic converters axial catalytic converters, ie honeycomb bodies through which radial or axial flow can occur, and also so-called diagonal catalytic converters can be used without further notice.
- Diago nal catalysts should be understood to be those which have flow paths in the interior of the catalyst carrier body which have both a radial and an axial directional component.
- the holding elements are plate-shaped.
- the holding element is designed as an essentially flat plate.
- the use of a flat plate is particularly advantageous since a flat plate with an opening adapted to the shape of the catalyst carrier body is easy to produce and can also be easily adapted to the internal shape of the exhaust pipe housing.
- the holding element has an approximately elliptical shape for obliquely arranging a catalyst carrier body which is round in cross section.
- the opening of the holding element has a collar at its edge.
- the collar can be produced using known manufacturing processes, such as, for example, a drawing process, when working in the opening.
- the collar serves, among other things, for better fastening and ensuring better dimensional stability of the actual catalyst carrier body without a tubular casing. Welding the collar onto the catalyst carrier body is easier than welding into a collarless opening.
- it is particularly expedient if the edges are flanged on the narrow sides, so that an obliquely inserted catalyst carrier body rests on the flanges on both sides.
- a body in the axial type with a honeycomb structure or, in a likewise preferred manner, in a radial type also with a honeycomb structure can preferably be used as the catalyst carrier body.
- a method for producing a catalyst carrier body ready for installation in an exhaust gas line housing is created, in which, after winding or packaging or wrapping of at least partially structured sheet metal layers, this is carried out directly by a manufacturing device for producing the actual catalyst carrier body in a Holding element provided opening is inserted and fastened there, in particular welded or attached by positive locking.
- the opening is preferably designed in such a way that the longitudinal axis of the catalyst carrier body is inclined with respect to a direction essentially perpendicular to a plane which characterizes the extent of the holding element, the retaining element directly sealingly and completely around the outer surface of the catalyst carrier body Opening is attached.
- the catalyst carrier body produced with this method and provided with the holding element can thus be transported separately and, in accordance with the external design of the holding element, can be used in any shape of an exhaust pipe housing and can be fastened to or in this in such a way that the holding element represents a baffle plate and the exhaust pipe housing divided into an inflow chamber for the exhaust gas to be cleaned and an outflow chamber for the cleaned exhaust gas.
- the actual catalyst carrier body is only wound, layered or entwined, in particular from sheet metal layers already coated with ceramic and / or catalytically active material, at least in some areas, without the contact points of several superimposed layers being soldered.
- sheet metal layers already coated with ceramic and / or catalytically active material, at least in some areas, without the contact points of several superimposed layers being soldered.
- the catalyst carrier body is produced from sheet metal layers made of expanded metal.
- the catalyst carrier body is preferably made of a film with a corrugated structure by being introduced arbitrarily into a space with internal dimensions and internal configurations which correspond to the external shape of the actual catalyst carrier body.
- the film having such a corrugated structure is "shot" into a space of this type through a corresponding inlet opening, so to speak, so that a chaotic layered catalyst carrier body is formed.
- the holding element is preferably used as a partition in an used gas line housing and there glued sealing to the housing wall, welded, or rolled with its edge in a circumferential housing edge, so that two chambers connected to each other via the catalyst carrier body are formed.
- a muffler housing according to the invention with an obliquely inserted catalyst carrier body can be formed.
- FIG. 1 shows a catalyst carrier body without a casing tube with a holding element
- Fig. 3 shows the insertion of the catalyst carrier body with the holding element in a muffler housing according to an embodiment of the invention.
- the holding element 3 is flat and has a rectangular shape, which is intended for insertion into an essentially rectangular exhaust pipe housing 6. So that the catalyst carrier body 1, which is round in cross section, can be held obliquely in the holding element 3, the opening 4 in the holding element 3 is elliptical. For better fastening of the inner periphery of the opening 4 of the holding element 3 to the outer periphery of the catalyst carrier body 1, the periphery of the opening 4 can be provided with a flange 5.
- the catalyst carrier body 1 with the holding element 3 thus forms a unit which is transportable and which ensures that after the winding, layering and / or devouring of the catalyst carrier body 1, the latter retains its shape and does not unintentionally dissolve again or from a compact to a non-compact, loose form jumps back.
- the oblique arrangement of the catalyst carrier body in the holding element 3 has the advantage that the height of the exhaust pipe housing 6 can be made smaller than with the catalyst carrier body 1 installed vertically.
- the exhaust pipe housing 6 consists of a housing part 7 surrounding an inflow chamber 10, into which an exhaust gas inlet 9 opens, and a housing part 8 surrounding an outflow chamber 11, from which cleaned exhaust gas exits through an exhaust gas outlet.
- the catalyst carrier body 1 is held in a holding element 3 in the form of a flat plate, the outer dimensions of which are adapted to the inner dimensions of the exhaust gas line housing 6 formed from the upper housing part 7 and lower housing part 8.
- the holding element 3 is both fixed to the catalyst carrier body 1 in the opening 4 and essentially sealing and also firmly and essentially sealingly connected to the inside of the exhaust pipe housing 6, so that the holding element 3 acts as a partition between the inflow chamber 10 and the outflow chamber 11 is used.
- the exhaust gas flow is deflected several times in the exhaust pipe housing, which also achieves good sound insulation.
- the oblique arrangement of the catalyst carrier body 1 in the exhaust pipe housing 6 ensures a relatively large external inflow surface for the exhaust gas stream entering the catalyst carrier body 1.
- a catalyst carrier body 1 without a jacket tube is provided according to the invention with a rectangular and essentially flat holding element 3.
- the outer shape of the holding element 3 is designed so that the housing halves 7, 8 forming the exhaust pipe housing 6, which have a circumferential flanged edge, between their flanged edges, the plate circumferentially with the housing by a corresponding flanging process, welding process or similar known connecting process to one Connect uniform exhaust pipe housing 6.
- the catalyst carrier body 1 is fixedly arranged in the interior of the exhaust pipe housing 6 with an inclined longitudinal axis 2, as shown in FIG. 3.
- the exhaust gas stream enters through the exhaust gas inlet 9 into the inflow chamber 10, which is formed by the upper housing part 7 and the holding element 3. After passage and thus after cleaning in the catalyst carrier body 1, the cleaned exhaust gas stream exits the exhaust pipe housing 6 through the exhaust gas outlet 12 through the exhaust chamber 11.
- a catalyst which can be adapted to a wide variety of installation configurations and is inexpensive to produce is thus created, in particular for use in small engines. It can be constructed in particular from pre-coated sheet metal layers and can be transported without additional elements and without a casing tube, so that the manufacture of the catalyst support body and the installation in a muffler can take place at different locations without additional manufacturing steps or transport locks being required.
