The present invention also relates to the manufacture of a muffler or muffler for an exhaust system of an internal combustion engine and a catalyst converter mounted in the muffler or muffler of an internal combustion engine, particularly a small engine. method. It is known that the catalyst converter used in the exhaust system of an internal combustion engine is in the form of a honeycomb. The honeycomb pupae are made from metal sheets that are stacked or entangled or twisted together. The other honeycomb ships sequentially contain sintered or extruded materials. Those catalytic converters are used to ensure that the convertible gas still remaining in the exhaust gas is further converted. A high number of ever-increasing exhaust gas regulations, especially for vehicles, means that at the same time the catalyst converter is designed to achieve almost complete conversion, that is, the catalyst conversion The device is in use for an extended period of time. The development of catalyst converter technology is especially along the route of maximizing the active surface area of the catalyst. Therefore, especially those honeycomb ships having a large number of passages in their entire cross section are used. However, in addition to the possibility of increasing the surface area involved, the length and volume of the catalytic converter and its cross section have also been increased. But that requires a lot of available space to accommodate the catalyst converter in the exhaust system. In addition, as catalyst converters continue to increase in size, the workflow for producing catalyst converters therefore becomes more expensive. In addition, with regard to large-scale catalyst converters, special attention must be paid to their corresponding mechanical and thermal changes during operation.

Description of the invention (3) Reveal that the two branches are installed in a curved configuration One of the engine sections is a tube in the vicinity. The two tubes have holes inside. A catalyst active layer is arranged between those two tubes. One of the catalyst converters according to the present invention is particularly suitable for use. The scope is about small engines. The term small engines used after this refers to engines with a cubic capacity of less than 250cc. Engines like this are used especially in lawn mowers, motor-driven saws, and Mobile generators, two-wheeled steam locomotives and similar applications. For saws, lawnmowers, and other flower ball equipment, the people who operate these appliances are often directly in the exhaust area of the small engine for more than an extended period of time. For this reason, the catalyst for exhaust gas cleaning is Place is particularly important. Also note DE 38 29 668, which reveals that in a small engine, the catalyst converter is used in a partition wall that extends approximately perpendicular to the direction of circulation.

It is an object of the present invention to provide a catalyst conversion in a housing Device for an exhaust emission system of an internal combustion engine (preferably a small engine). The catalyst converter can be manufactured in a few working steps. The converter is very compact, but it can still provide sufficient catalytic active surface area, so that it can comply with the limit values set by the regulations on the exhaust emission characteristics of internal combustion engines.

A case of the invention (4), the case will not make the space obtained by the dense catalyst converter lose its value again. Another object of the invention is to provide a method for producing a compact catalyst converter carrier, which ensures the continuous production of the catalyst converter carrier 'while avoiding a high production cost. This object is achieved by a catalyst converter having the features as in item 1 of the patent application for the present application and a method having features as in item 18 of the application for the patent application. The more favorable forms and characteristics are detailed in their subsidiary items. The Shell Standard Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs has printed an exhaust system for an internal combustion engine (especially a small engine). The catalyst converter inside has at least one The metal sheet is twisted or entangled, it forms a channel through which exhaust gas can pass, and it at least partially bears against the skull. When the entire cross-section of the shell is examined, the sheet has a structure such that the cross-sectional area enclosed or enclosed by the closed channel constitutes at least half of the total cross-section of the shell, and the contact The media converter has a maximum of two layers. Limiting the catalyst converter to a maximum of two layers makes it possible to achieve a very compact catalyst converter requiring a small amount of space. For this purpose, the structure of the sheet is required. In terms of space utilization, in addition to the channel effect of the catalyst converter, it can also provide sufficient catalyst active surface area for supply. The use of up to two layers is also beneficial for heating the catalyst converter to its useful or operating temperature, as it contains less mass to be heated than other expensive and complex structure catalyst converters. In addition, the restriction of up to two layers is actually advantageous later. In addition to being flexible, the catalyst converter also has a high degree of stability and rigidity in appearance. For a better application in the field of small engines, the catalyst converter of this case can provide at least a satisfactory catalyst conversion efficiency for exhaust gas.

Description of the invention (5) The enclosure The cross-sectional area constitutes at least two-thirds of the total cross-section of the general body, which can achieve one improvement in catalyst conversion. If the sheet provided with the catalyst active material is twisted or entangled, the resulting The structure becomes opposite to each other, which allows the trapped cross-sectional area defined by the channel to be placed in an area surrounding the center point of the catalyst converter, and the center point is arranged in a The remaining area of the channel is not completely provided. These can be reached in the flattened cross-sectional area of the catalytic converter, and the same is true for circular, oval, or multi-sided catalytic converters. Concentrating around the center point The enclosed cross-sectional area makes it possible for the exhaust gas to be fully acted on the surface of the channel facing away from the center point. In addition, the structure of up to two layers can be particularly advantageous, which makes The flow resistance that should be formed in the channel will not be higher than that of the cross section that does not completely contain the channel. One embodiment of the catalyst converter in this case provides that these mutually opposed structures are entangled or staggered together, but each other No contact. In this way, a pseudo-channel geometry is given to the empty area. The mutually opposed configurations make the enclosed cross-sectional area constitute at least three-thirds of the total cross-section of the shell Secondly, it becomes possible. With regard to small appliances or equipment that must be manually moved in some cases, from the structural point of view, it is very important for them to have a small size and light weight. The media converter can help by having a stabilizing reinforcement. This reinforcement ensures that the catalyst converter can still enjoy its rigidity without excessively restricting its elasticity. The stable reinforcement also It can be designed to show a bearing function for small appliances or equipment. Due to this arrangement, the catalyst converter in this case can also be fully integrated into the small appliance. Please read first · Read the note on the back. Please fill in this%.

The casing and the contact The media converter is then in a position that is also incorporated in the details and explanations of the torsional rigidity and structural engineering involved. A catalyst converter, particularly capable of resisting shock, vibration and rolling, with the catalyst Each channel of the converter is provided with a metal sheet against a reinforcing member. In this respect, the resistance can be supported by the channel forming sheet with an upper side and a lower side respectively with its upper side and lower side. A stiffener is increased. Another possibility of manufacturing a catalyst converter that has a high degree of stability in the shape and also a high degree of elasticity involves constructing the contact with an unstructured sheet and a structured sheet. Media converters are widely available. This layer can be combined with a device for stabilizing the reinforcement. A preferred embodiment of a catalyst converter has an unstructured sheet with an upper side and a lower side, where in each of the upper side and the lower side An additional structured sheet is arranged between the two. This structure is especially a wavy, curved, fan-shaped, or folded sheet. It may also have a microstructure as well as cuts and openings. The contact surface area can also be increased in this manner. With regard to the structure, properties and type of this layer, the attention is particularly directed to EP 0484 364, WO 93/20339, EP 0 152 5δ0 and DE 29 611 143. Printed by the Central Government Bureau of the Ministry of Economic Affairs, Shelley Consumer Cooperative (please read the precautions on the back V, and then fill out this page). Three catalyst sheets (the outermost sheet is structured) are used to make catalyst conversion. This is enough to make it possible for the catalyst converter to be held in the ordinary place only by the clamping force of the outermost sheet. If at least a part of the layer of the catalyst converter is elastic, this will facilitate the holding effect. This is especially the part of the layer that holds up a reinforcement, in particular the housing, or the small device or appliance or the wall of the internal combustion engine. In a further embodiment, in order for the catalyst converter to achieve-high -9-• This paper size is applicable to the National Standard for Difficulties (CNS) A4 specification (210 × 297 mm > ~ ------ A7 B7 V. Description of the invention (7) (Please read the note ^^ on the back before filling this page). It must have a layer of structure with a first metal sheet and a second metal sheet. In this arrangement, the first sheet is preferably 1.5 to 5 times thicker than the second sheet, especially between 2 and 4 times. When using a metal foil between 20 μm and 100 μm, this makes It is possible to use a thinner foil that is particularly desirable in structure without giving up the idea of a catalyst converter that can stabilize itself. Therefore, it is preferred that the first sheet is unstructured, The second sheet is structured. A further embodiment of the catalyst converter in this case is to provide the catalyst converter with a flat cross-section β if it is applied to the catalyst converter from the outside. The direction of the force is known, so having a flattened cross section allows A catalyst converter that can enjoy stability in this direction becomes possible. In this case, the catalyst converter can also be designed so that it has a better direction corresponding to the action of external force. The catalyst converter can The isotropic direction is elastic and may also need to be plastically reactive. The damage to the catalyst converter can be avoided by the area where the catalyst converter is established, which involves an excessively large load, which involves the Plastic deformation is used to receive and absorb these forces. The catalyst converter in the case of the Consumers' Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs can be arranged in an exhaust emission system that is usually taken out of the internal combustion engine. However, The catalyst converter of this case can also be used in the exhaust gas emission system placed in the box of the internal combustion engine. In both cases, it is hoped that the shell of the catalyst converter of this case can become the exhaust gas emission system. This can ensure that when the catalyst converter is heated up, it can dissipate heat to the outside through flow conduction. The casing can be the exhaust emission system A curved pipe or a muffler or muffler. This can ensure the compact installation of the catalyst converter without the need for an extra space for the catalyst conversion. -10- This paper applies the Chinese National Standard (CNS) A4 specification (210X297 metric t) A7 B7 printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs 5. Description of invention (8). According to a further aspect of the present invention, in order to achieve a dense use of the space involved, use A muffler or muffler for an exhaust system of an internal combustion engine (especially a small engine) having means for accommodating the above-mentioned catalyst converter. This is, for example, a housing that is appropriately designed and especially adapted to the use, The housing facilitates the catalyst converter to be placed therein and fixed therein. This can be achieved by using a tubular box as the shell «, and by a suitable space configuration in the engine case of the internal combustion engine. Achieve · Especially for small engines, the combination of the muffler and the catalyst converter makes it possible for the exhaust system to maintain a small size. Preferably, a part of the muffler or muffler has a device for fixing the catalyst converter. This can be a toothed, V-shaped, laterally lamellar, grooved, grooved, or similar structured device. If toothed or similar devices are used, they will at least interact with the oppositely placed sheet. The toothed device fits into the opposedly placed sheet, thereby holding the entire catalyst converter. The service life of the catalytic converter also depends on the individual operating mode of the internal combustion engine and its use range. If the engine is repeatedly operated only within a short period of time 'and if the engine is led to a strong force acting on the engine from the outside world', these will reduce the useful life of the catalyst converter. It is therefore desirable to be able to replace the catalytic converter in place. In the case of the muffler or muffler, the catalyst converter may, for example, be arranged in a top frame and a bottom shell vessel. One of these two and a half halves preferably has a reinforcement, whereby the catalyst converter can be applied to the -11- this standard is applicable to the Chinese national standard ¥ (CNS) A4 secret (210X297 mm) * --- (Please read note f on the back before filling this page).

Immediately thereafter, at least a part of the elongated entity 50 around which the sheet is wound is divided into a plurality of parts 51. A laser is used here as a cutting unit 52. It can cleanly cut out the part 51 from the entity 50. This cutting operation can be performed particularly in such a manner that the part 51 does not require post-processing. The part 51, like the catalyst converter entity completed after that, can be used as the catalyst converter 1. For this purpose, the part 51 is then provided with a catalyst active coating or in In the winding operation, the sheet 49 and the 贲 艎 50 have the coating, respectively. Figure 10 shows a further method of producing a catalyst converter carrier. -19- This paper size applies to China National Standards (CNS) A4 specification (210 X 297 mm) A7 B7 printed by the Shellfish Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 5. Description of the invention (Γ7) method. A catalytically active coated sheet 54 is guided by an infinitely rotating sleeve 53 to a reversing shaft 55. From there the sheet 54 is taken to a first contoured shaft 56 'which is combined with a second contoured shaft 57. The geometry of the two flanking wings with contoured shafts determines the structure of the sheet 54. It was then applied to a hollow solid 艟 58. The hollow solid sheet 58 has a second structured sheet 59 disposed inside, which sheet has also been provided with a catalytically active coating. The hollow real ship 58 and the second sheet 59 can be manufactured, for example, by applying the sheet 54 from a formed layer obliquely to each other to the real sheet. The entanglement effect is shown by the dotted line 60. However, the hollow solid 1158 can also be a tube with a second sheet 59 already inserted. In a slightly different method, the structured sheet 59 is not placed before being divided into parts 51, but only They are placed after they have been cut. Fig. 11 shows a step-by-step production method of catalyst-converted steam turbine load. In this example, the sheet 54 provided with a catalytically active coating is also applied to the hollow entity 58 from an infinite shaft 53 (not shown). The winding effect can be seen from the confrontation between adjacent regions of the winding layer. The winding operation can be carried out particularly in such a manner that the channel 5, as shown by the dotted line, is not interrupted by the winding from the viewpoint of continuity. The same situation applies to the channel of the sheet 54 to which it is applied. The fact is that the butt welding 60 in the example of the sheet 54 is applied at an angle to the hollow real skull 58 'means that the catalyst converter carrier manufactured in this way can have a particularly stable structure. The angled relationship between the butt welds has an advantage, that is, the catalyst converter carrier does not have any axially extending peripheral seams or joints β. On the contrary, the load at the seams is distributed to the entire periphery.

V. Description of the Invention (IS) The operation of printing the film 54 by the Shellfish Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs can also be effective in such a way that the hollow entity 58 of this layer is almost effectively clamped. The connection between the sheet 54 and the actual sheet can be made by the operation of applying the sheet or also by the direct welding after the next working step. The sheet 54 may also be, for example, glued and then welded. "In a slightly different production method, the hollow solid sheet 58 is again manufactured from one layer, as shown in Figure u. However, this time the hollow solid is formed in such a way that it has an overlapping area 61, as shown by a short line. The overlap region 61 then stabilizes the hollow solid. At the same time it can be used to create a connection or union. For this purpose, within a structure, the overlapping area 61 has an adhesive or a lead, after which the bonding material is applied to the area. A relative procedure using the sheet 54 is also used. The elongated hollow body 58 having the applied sheet 54 manufactured in this manner is neatly raised to a moderate temperature in a welding rafter, so that the welded object produces a durable material in the heavy-man region 61. Sexual connection. In this example, the sheet 54 connecting the hollow body 58 to the application is also manufactured by welding. After that, the individual parts 5l are cut out. Fig. 12 shows a method for carrying a catalyst converter which can be manufactured, for example, as described with reference to Fig. Π. The still wide sheet 54 is transferred from the infinite rotation shaft 53 to a first shaped rotation shaft 56 and a second shaped rotation shaft 57. After the contouring operation, the sheet 54 is cut into four individual sheets 54.1, 54.2, 54.3, and 54.4. This is achieved by a cutting device 62 which has a blade 63 for cutting. From there, the sheets 54.1 to 54.4 that should be cut are transferred to the relatively hollow solid «58.1 to 58.4. Each of them is wound on an opposite entity. The production method of this example-21- This paper size applies the Chinese National Standard (CNS) A4 specification (2 丨 0 × 297 mm)-(First 53.

Description of the invention (19) can be suitable for continuous tracking work procedures as the hollow The actual ships 58.1 to 58.4 can also be manufactured successively in the same way as a workstation placed upstream. Figure 13 also shows the production method of a catalyst converter. A structured sheet 65 and an unstructured sheet 66 are introduced into a roller object 64, as in the case of a sardine can opener, and are introduced into a groove 67 in the roller object 64. When the roller object 64 is rotated, the two sheets are wound to form a layer. The shape of the catalyst converter 1 manufactured in this manner depends on the geometry of the roller object 64. The holes formed in the catalyst converter i manufactured in this way can be large or small, depending on the needs involved in the individual. An added, especially a structured sheet can also be introduced into the hole. In the development of the production method of the catalyst converter 1 like this, the roller wheel 64 can be left there, and then it is used for stability by the thickness of its material. The 14th circle shows another production method of a catalyst converter 1. The catalyst converter 1 is manufactured by stacking a structured sheet 65 and an unstructured sheet 66 on top of each other. In this way, the catalytic converter 1 has a maximum of two layers 11, the two layers having an area 6 that is not clustered inside, the enclosure is defined by the periphery of the passage, the enclosure is a closed structure. The end 68 of the structured and unstructured sheet 65, 66, that is, the end beyond the projection of the next actual catalyst converter 1, is vocalized in the direction indicated by the arrow to form a surround around the touch. The outer box of the media converter. For this purpose, the operation of bending the end 68 is not only realized to be advantageous for a single sheet, but also effective for all the sheets brought together in one working step. It does not matter whether the sheet involved is a structured sheet 65 or an unstructured sheet 66. For this purpose, a more advantageous method is to unfold the end 68 (please read the precautions on the back before filling this page).
