- a carrier body for a catalytic reactor is known from DE 88 16 154 U1, the honeycomb body of which is made in one piece from metallic corrugated bands, the sensor being arranged on the carrier body in such a way that part of the sensor is inside the honeycomb body and one Part of the sensor extends outside the honeycomb body or is straight, so that the part of the sensor that lies outside the honeycomb body extends relatively far away from the honeycomb body.
- a carrier body for a catalytic reactor is known from DE 88 16 154 U1
- the honeycomb body of which is made in one piece from metallic corrugated bands
- the sensor being arranged on the carrier body in such a way that part of the sensor is inside the honeycomb body and one Part of the sensor extends outside the honeycomb body or is straight, so that the part of the sensor that lies outside the honeycomb body extends relatively far away from the honeycomb body.
- Such an arrangement requires a relatively large amount of space when installed in the exhaust system of an automobile.
- a measuring sensor is understood to be an arrangement that allows values of at least one parameter of the fluid to be recorded when it flows through the honeycomb body.
- the parameter can be any physical and / or chemical variable that can be determined directly and / or indirectly.
- the sensor can work according to any physical and / or chemical measuring principle. It is also possible for more than one sensor, in particular two, three or four sensors, to be formed in the honeycomb body.
- the measuring sensor also includes a data connection via which the recorded
- the cavities of the honeycomb body can be channels which extend from the first to the second end face of the honeycomb body and thus carry the fluid.
- different types of cavities can also be formed, for example channels which are interrupted by caverns.
- openings and connections from adjacent cavities are also possible.
- at least some of the cavities each have an opening in the first end face and in the second end face.
- the cavities can be at least partially closed, if necessary also with an at least partially flowable material, so that flow cul-de-sacs or flow bottlenecks form.
- Such measures can be taken to set up open or closed particle filters. These are used, in particular, to filter out the particles contained in the exhaust gas of an automobile, such as soot particles, from the exhaust gas.
- the honeycomb body according to the invention can in particular also be used as a catalyst carrier body in the exhaust system of an automobile.
- a coating of ceramic material for example a washcoat, can be applied, in which the catalytically active material is introduced.
- This ceramic coating leads to a further increase in the reactive surface of the catalyst carrier body.
- the honeycomb body according to the invention can be equipped with a corresponding coating which can be used as a storage medium for at least one component of the Allow exhaust gas. This can be, for example, a coating that adsorbs nitrogen oxides (NO ⁇ ) at low temperatures and desorbs at higher temperatures.
- the sensor is in particular designed and introduced into the honeycomb body in such a way that several cavities of the honeycomb body are at least partially penetrated.
- the at least one parameter in the fluid that flows or can flow through these cavities is determined.
- the fluid flowing through these cavities is averaged.
- the honeycomb body according to the invention advantageously allows the control and monitoring of at least one parameter of the fluid, while at the same time the space required for the installation of the honeycomb body with a sensor is small, since the angle between the first and second section of the sensor is arbitrary and thus the space required for the Available space can be adjusted.
- the curvature of the first section can advantageously be adapted to the curvature of the honeycomb body in the region of the exit of the first section.
- the at least one sensor is designed as a lambda probe.
- lambda probes are an important sensor that allow the fuel / oxygen ratio to be determined. Furthermore, it is advantageous to form one lambda probe in front of the honeycomb body or in the initial area of the honeycomb body, preferably within the first 20% of the length of the honeycomb body, and another in the end area, preferably within the last 20% of the length of the honeycomb body or in the direction of flow behind To train honeycomb bodies.
- the at least one sensor comprises at least one of the following parameters of the fluid: a) temperature; b) proportion of at least one component of the fluid;
- the exhaust gas generally has a high temperature and, moreover, the catalyzed reactions are exothermic, the temperature of the honeycomb body, or of the exhaust gas flowing through it, is an important parameter for both the operating state and the general state of the Honeycomb body, as well as for the degree of implementation that is achieved with the catalytic reaction.
- the sensor can also advantageously detect a proportion of at least one component of the exhaust gas, such as the oxygen proportion, the nitrogen oxide proportion, the ammonia proportion and / or the hydrocarbon proportion.
- the measured values recorded in this way can also can be used advantageously for controlling and monitoring at least the exhaust system of an automobile.
- the formation of combined measuring sensors is also possible and according to the invention, which, for example, on the one hand perform the function of a lambda probe and on the other hand additionally also detect the temperature and / or a proportion of a component of the exhaust gas.
- the at least one measuring sensor has means for preventing heat conduction, for example, it can at least partially surround a heat-insulating layer near the first partial area.
- the first section of the sensor is closer to the honeycomb body than in the case of an angled version of the sensor.
- the honeycomb body according to the invention is used in the exhaust system of an automobile, for example as a catalyst carrier body, adsorber body, particle filter, particle trap or as a combined element as a combination thereof, the honeycomb body and therefore also the sensor are high temperatures, for example up to 1000 degrees Celsius and more depending on the position of the honeycomb body in relation to the internal combustion engine, exposed to a strong thermal load on the material, especially the sensor. According to the invention, this effect is taken into account by the formation of a heat-insulating layer, in particular in the first partial area of the sensor.
- This thermal insulation is designed in such a way that it is adapted to the high thermal transients and / or gradients that occur and that these do not lead to rapid wear of the thermal insulation material under the operating conditions, for example in the exhaust system of an automobile.
- Casing tube of the housing or of the heat structure e.g. also by heat Radiation to hinder or even prevent temperature-sensitive sections of the sensor.
- the angle enclosed by the first partial area and the second partial area is 60 to 120 degrees, preferably 75 to 105 degrees, particularly preferably 85 to 95 degrees.
- angles of less than 90 degrees are advantageous.
- an angle of 90 degrees allows the smallest possible space requirement for the installation of the honeycomb body including the sensor.
- Angles of more than 90 degrees can also be advantageous if the angle has at least a portion in a plane encompassing the direction of flow. Such angles reduce the heating up of the first section and in particular of data connections formed in the first section and wear problems in these areas.
- the angle enclosed by the first partial area and the second partial area is essentially 90 degrees.
- At least a portion of the sensor is at least partially curved.
- the angle enclosed by the first and the second partial area is determined as the angle between the tangent in the contact area between the first and second partial area and the axis or tangent of the other partial area.
- the curvature of the curved partial area is adapted to the curvature of the honeycomb body and / or to the geometric conditions in the honeycomb body.
- an adaptation of the curvature of the first partial area to the outer curvature of the honeycomb body, or of the tubular casing of the honeycomb body is advantageous, since this results in the greatest possible space saving. Furthermore, an adaptation of the curvature of the second partial area to the geometric conditions in the honeycomb body can allow a very specific selection of the parts of the fluid, the measured values of which are recorded by the measuring sensor.
- An adaptation to the geometric conditions in the honeycomb body means, for example, that when the honeycomb body is formed from at least partially structured and essentially smooth metallic layers that are twisted in an involute manner, the second partial area also has an essentially involute-like shape. In particular, specific partial flows can be selected in which the measured values are recorded.
- the honeycomb body is at least partially formed from at least one metallic layer.
- honeycomb body from metallic layers, for example sheet metal layers and / or metallic fiber layers, preferably from high-temperature and corrosion-resistant metals, for example high-temperature-resistant steels, advantageously enables the construction of honeycomb bodies which also withstand the harsh conditions in the exhaust system of an automobile can withstand.
- metallic layers also enables a very variable design, in particular of the cavities of the honeycomb body.
- At least one at least partially structured layer with at least one essentially smooth layer and to twist at least one stack.
- two stacks can be wound in an S-shape in opposite directions, or three stacks can be twisted together.
- An essentially smooth layer is understood to mean a layer which may have microstructuring, but whose structuring amplitude is smaller, preferably substantially smaller, than the structuring amplitude of the at least partially structured metallic layer.
- the honeycomb body is wound up from at least one at least partially structured metallic layer and optionally at least one essentially smooth metallic layer.
- the honeycomb body consists of metallic layers, part of which is a sheet metal layer which cannot be flowed through, possibly perforated at least in parts, while another part is made of at least partially flowable material.
- metallic fiber material in particular sintered metallic fiber material, is possible as an at least partially flowable material.
- hole shapes As well as special orientations of the holes with respect to the flow direction of the honeycomb body are also possible and according to the invention.
- cavernous cavities By forming holes, the dimensions of which are greater than the structural repeat length, in the or in individual layers, after winding or twisting, cavernous cavities can be formed, in which the fluid flow is swirled as it flows through the honeycomb body.
- the catalyst support bodies can be made lighter and with less material use with the same conversion effectiveness.
- honeycomb body from ceramic material is possible in various ways.
- the honeycomb body can be extruded or built up in layers from ceramic powder.
- Ceramic honeycomb bodies can be used as a catalyst carrier body, as an adsorber body or as a particle filter if the cavity walls and / or a corresponding coating are designed in the exhaust system of an automobile.
- honeycomb bodies can include the layer-by-layer application of a solidifiable mass which is repeatedly cured by temperature or light. In this way, structures of any complexity can also be produced with undercuts. This process, which comes from rapid prototyping, is already being used in part in series production.
- FIG. 4 schematically shows a third exemplary embodiment of a honeycomb body 1 according to the invention in cross section.
- Both the first partial region 8 and the second partial region 9 are straight in this.
- Both partial areas 8, 9 are connected in the contact area 12, in which they enclose the angle W, which in the third exemplary embodiment is essentially 90 degrees.
- the angle W is spanned in the third embodiment in the second plane 19.
- An angle W of essentially 90 degrees allows, in a particularly advantageous manner, a very space-saving construction of honeycomb body 1 and sensor 7.
