Definitions
- the present invention relates to a catalytic converter for a small motor, in which a honeycomb body coated with catalytically active material is arranged in a silencer housing arranged close to the motor.
- DE-OS 38 29 668 already provides an example of an exhaust silencer for two-stroke engines, which contains a catalytic converter for exhaust gas purification in its interior.
- EP 0 470 113 B1 also discloses a metallic catalyst carrier body which is particularly suitable for fastening in the partition of a silencer housing.
- the object of the present invention is therefore a catalytic converter for a small engine, which is very inexpensive to manufacture, requires the smallest possible design changes to existing small engines and their exhaust systems, and yet can remove a considerable proportion of the pollutants from the exhaust gas catalytically.
- a catalytic converter according to claim 1 is used to achieve this object, a corresponding manufacturing method being specified in claim 11.
- Advantageous refinements are specified in the respective dependent claims.
- Catalytic converters usually contain honeycomb bodies in order to provide a sufficiently large surface for a catalytic conversion in a partial volume of the exhaust system.
- honeycomb bodies are produced in particular from metal sheets, at least some of these metal sheets being structured in such a way that channels which are permeable to exhaust gas result overall.
- alternating smooth and corrugated sheet layers are used.
- a large number of structures come into consideration for the present invention, so that sheet metal layers with two different corrugations or sheet metal layers with corrugations arranged alternately obliquely to one another can also be used.
- this method has many advantages in terms of production technology and leads to a simple, but durable catalytic converter.
- a silencer housing for small engines consists of two or more individual parts, in particular half-shells and a partition, which can be connected by means of a simple connection process, e.g. B. flanging or welding. These housing parts can Assembling can be used simultaneously for the shaping of the honeycomb body, without the need for additional tools.
- a stack of sheet metal layers with a larger volume than the partial volume to be filled in the muffler housing is simply placed in the intended position when the housing is assembled and squeezed into its final position and shape when the housing parts are assembled. Even if 15 to 30% of the channels are plastically and / or elastically deformed, namely at the lateral ends of the stack and in the outer edge areas, enough cells remain gas-permeable, so that effective catalytic cleaning is ensured.
- the lateral ends of the stack should be held on or in the walls of the housing in a preferred embodiment.
- the sheets are already coated with catalytically active material before being fitted in the silencer housing, either by using sheets already coated for the entire production process or by coating a prefabricated stack of sheet metal layers as a whole.
- a major advantage of the catalytic converter according to the invention is that the considerable deformation of the channels is partly plastic and partly elastic, so that the honeycomb body remains under a pretension which prevents the sheet metal layers from loosening under all operating conditions, in particular thermal alternating loads.
- the honeycomb body will be under maximum prestress in a catalytic converter manufactured according to the invention, since it is deformed everywhere beyond the elastic limit. This prevents relative movements between the sheet layers even with decreasing elasticity with increasing temperature.
- sheet metal layers with so-called transverse microstructures which are known in the prior art, are also particularly suitable for the present invention. These microstructures increase the effectiveness of the catalytic conversion and also cause the sheet metal layers to be clamped together, so that they cannot move against each other, especially under the high elastic preload, even under the most unfavorable conditions. This also applies if not all sheet metal layers, but only a part of them, are attached to the silencer housing with their ends.
- the stack to be squeezed into the muffler housing is adapted in its initial form to the shape of the partial volume to be filled and to the degree of deformation of the individual regions to be expected during the crushing, although the volume of the stack is preferably at least 5%, preferably should be at least 10% larger than the partial volume to be filled.
- silencer housings composed of at least two parts
- clamp the crimped ends of the stack in the joint between these parts in order to enclose the honeycomb body to fix overall.
- This can be carried out both in the case of stacks formed from individual sheets, and in the case of stacks which are wound, folded or laid in a meandering shape from one or more sheets after the ends have been squeezed together.
- the ends of the stack can be included in the technology previously used for assembling the silencer housing, so that the attachment can be carried out, for example, by flanging, welding with a weld seam or spot welding.
- the catalytically active coating on the metal sheets generally does not interfere, so that no additional processing steps are necessary to remove them.
- FIG. 1 shows a longitudinal section through a muffler housing with a schematically indicated installation location of a catalytic converter
- FIG. 2 shows in cross section the parts of a silencer housing, including a stack, shortly before assembly,
- FIG. 3 shows a cross section along the section line III-III in Figure 1 by a silencer housing after assembly
- Figures 4, 5, 6, 7 and 8 different forms of stacks of at least partially structured sheet metal layers.
- Figure 1 shows schematically in longitudinal section a silencer housing 3 for a small engine.
- the exhaust gas enters the exhaust gas inlet 1
- Lower part 3.2 of the muffler housing from where it reaches the upper part 3.1 of the muffler housing through openings in a partition 3.3. From here it flows through the channels 7 of a honeycomb body 4 and then reaches the exhaust gas outlet 2.
- Upper part 3.1 and lower part 3.2 of the muffler housing and the partition 3.3 are connected to one another in the area of a parting joint 3.4, for example by flanging or by a weld.
- FIG. 2 schematically illustrates in cross section the joining of upper part 3.1, lower part 3.2, partition 3.3 of the muffler housing and a stack 8 of sheet metal layers 5, 6, the process of joining being indicated by arrows.
- the stack 8 is formed from alternately arranged individual smooth sheet metal layers 5 and corrugated sheet metal layers 6, which together form a multiplicity of channels 7 which are permeable to the exhaust gas.
- the sheet metal layers 5, 6 are coated with catalytically active material 10. This coating can either be applied to the sheet metal layers 5, 6 in a continuous process before all other processing steps, or else can be applied together after the stack 8 has been layered.
- FIG. 3 shows in cross section along the line III-III in Figure 1 an essentially completely assembled silencer housing with a crimped honeycomb body. It can be seen that the lateral ends 9 of the stack 8, which is still undeformed in FIG. 2, are now squeezed together, with numerous channels 7.1 also being plastically deformed in the edge regions of the honeycomb body. Nevertheless, especially in the inner region of the honeycomb body, there remain sufficient channels which are not plastically deformed and which are sufficient for the catalytic conversion of exhaust gas passed therethrough. However, these channels 7 are deformed considerably elastically by the squeezing forces exerted on the entire honeycomb body, so that the whole honeycomb body is under considerable pretension.
- the crimped lateral ends 9 of the stack of sheets are clamped between the upper part 3.1 and the partition 3.3 of the muffler housing and can be included in the usual connection technology of the muffler housing. As shown on the right side of FIG. 3, this can be a flanging 3.5. However, a welded connection 3.6 indicated on the left side of FIG. 3 is also possible, which also includes the ends of the sheet metal layers 5, 6 of the upper part 3.1, the lower part 3.2 and the partition 3.3.
- FIGS. 4, 5, 6, 7 and 8 show different initial shapes for the honeycomb body 4 to be integrated into the silencer housing 3 as a selection of the shapes that are possible overall.
- Figure 4 shows a trapezoidal sheet metal stack 11, made of smooth sheet metal layers 5 and corrugated sheet metal layers 6, in the lateral end regions 9 of the sheet metal stack 11 those sheet metal layers are longer, the ends of which have a longer path to the parting joint after assembly. In this way it is ensured that the ends of practically all sheet metal layers can be held reliably.
- FIG. 5 shows a meandering stack of sheets 12.1 in which a corrugated sheet layer 6 is layered in a meandering manner, with individual smooth sheets 5 being arranged between the individual layers. A similar configuration is shown in FIG.
- FIG. 7 shows an oval sheet stack 13 made of a smooth 5 and a corrugated sheet 6 as the starting stack.
- Such a stack can be achieved in a conventional manner by flattening a spiral sheet stack stacked with a cylindrical cavity.
- Figure 8 finally shows a particularly preferred embodiment in which only the smooth sheet metal layers 5 are to be included in the connection of the parting line. For this reason, the ends of the smooth sheet metal layers protrude to different degrees, depending on their way to the parting line.
- the corrugated sheet metal layers 6 are shorter and in their respective lengths adapted to the cross-sectional shape of the muffler housing and in turn equipped with a certain excess of volume, which is later reduced by plastic deformation.
- the smooth 5 and the corrugated sheet metal layers 6 are equipped with interlocking structures. Microstructures extending transversely to the direction of flow, as are known from the prior art, are particularly suitable for this purpose.
- the present invention creates the possibility of being able to apply exhaust gas catalysts to small engines on a broad basis in order to relieve the environment and the operating personnel of the small engines.
