    摘要： A honeycomb body, in particular a catalyst carrier body, for catalytic conversion of exhaust gases in an exhaust gas system, especially an exhaust gas system of an internal combustion engine, preferably an Otto engine, includes a central channel and adjacent discs defining a multiplicity of curved outer channels bounded by the discs. The outer channels extend outwards from the central channel and have one end opening into the central channel. At least some of the disks have a macrostructure forming a lateral boundary of the outer channels. An apparatus for catalytic conversion of exhaust gases includes a housing having an exhaust inlet opening and an exhaust outlet opening, and the honeycomb body disposed in the housing. An additional microstructure in some or all of the disks can increase the effectiveness of the catalytic conversion.

    摘要： A metallic honeycomb body has an axial length, a partial volume covering at least 55% of the length, a radial dimension of at least 20 mm and inflow and outflow end sides. Sheet-metal layers are structured permitting a fluid, particularly internal combustion engine exhaust gas, to flow through the body between the end sides. The layers each have a surface area, partial regions and end side edges. Each of the layers has a multiplicity of holes formed at least in the partial regions in the partial volume. The holes have a hole surface area of between 1 and 120 mm2. The layer surface area in the partial volume is reduced by 10 to 80%, preferably 35 to 60%, by the holes compared to a layer without holes. The partial volume is spaced from each of the end sides, preventing the holes from touching and cutting through the end side edges. The partial volume amounts, in particular, to more than 60%, preferably more than 90%, of the total honeycomb body volume. A highly effective coating for treatment of a fluid for most known forms of honeycomb bodies yet with a reduced use of coating material while still being able to specifically match properties of a honeycomb body in terms of mechanical stability, heat capacity, thermal conductivity and the like to the requirements of individual applications, is provided.

    摘要： A method for analyzing a condition of at least one partial volume of a catalytic converter through which a gas mixture flows, includes measuring a temperature with a sensor at least at one location or in a region within a partial volume during a change of chemical and/or physical properties of the gas mixture. The location or the region and a configuration of the sensor are selected in such a way that a reaction of the measured temperature to a change of the properties of the gas mixture is at least approximately representative of a reaction of the temperature in the partial volume of the catalytic converter. Set point values are determined for the respective change in the properties of the gas mixture on the basis of a thermodynamic model while taking physical boundary conditions and properties of the partial volume into account. The reaction of the measured temperature is determined and compared with the set point values.

    摘要： A catalytic converter has a carrier structure and a catalytically active coating adhering to the carrier structure, and is disposed downstream of an internal combustion engine of a motor vehicle for cleaning exhaust gas. A method for functional monitoring of the catalytic converter includes determining a temperature of the catalytically active coating and/or of the structure of the catalytic converter at least at one location. A temperature of the exhaust gas is determined upstream of the at least one location of the catalytic converter. At least first derivatives over time of both temperature values are formed. A difference of the derivatives over time is formed. An instant after a start of the engine at which the difference changes its sign is ascertained. An apparatus for functional monitoring of the catalytic converter includes at least one measuring sensor for measuring a temperature of the carrier structure and/or of the catalytically active coating. At least one device determines an exhaust gas temperature. A differentiation circuit forms derivatives over time of the measured or determined temperatures. A subtraction circuit forms a difference between the two derivatives over time. A comparison circuit ascertains an instant at which the difference changes its sign.
