    摘要： An internal combustion engine has an engine control for processing a number of measured values received over measurement lines, converting the measured values into control data for operating the engine and carrying the control data over engine feed lines to the engine, for instance for controlling at least one of fuel injection, air delivery and ignition with the control data. A method for controlling the internal combustion engine includes directly measuring a temperature of walls or structures of a catalytic converter disposed downstream of the engine, supplying a value of the temperature to the engine control over at least one data line, processing the value of the temperature in the engine control along with other measured values and using the processed value to control the engine. An apparatus for controlling the engine and for monitoring the temperature of the catalytic converter includes at least one temperature sensor integrated on or in walls or structures of the catalytic converter. An engine control receives a number of measurement data as input variables from measurement lines and derives control data for operation of the engine from the measurement data. Engine feed lines carry the control data to the engine. At least one data line delivers measured temperature values from the catalytic converter to the engine control as input variables in addition to other input variables.

    摘要： A catalyzer configuration, in particular for internal combustion engines, has a diffusor which widens in the direction of flow disposed upstream of a honeycomb body, a converger which narrows in the direction of flow downstream of the catalyst body, and at least one flow guiding body located within the diffusor and/or converger. In order to achieve a uniform inflow at the front side of the catalyst body without excessively throttling the exhaust gas flow, a flow guide body composed of a multiplicity of adjacent and/or imbricated channels having at least partially an increasing cross-section in the direction of flow is disposed in the diffusor. The individual channels preferably have an opening angle .alpha. that prevents burbling at the walls of the individual channels. In addition, the flow guide body can be coated with a catalytically active material, thus allowing the volume of the diffusor and/or of the converger to be used for housing catalytically active surfaces.

    摘要： A method for converting soot particles of an exhaust gas includes providing at least nitrogen dioxide or oxygen in the exhaust gas, ionizing soot particles with an electric field, depositing electrically charged soot particles on inner channel walls of at least one surface precipitator, and bringing at least nitrogen dioxide or oxygen into contact with the deposited soot particles on the inner channel walls of the at least one surface precipitator. A device for carrying out the method includes at least one surface precipitator having a plurality of channels through which the exhaust gas can flow and extending between an inlet region and an outlet region, and at least one deposit inhibitor for electrically charged soot particles provided in at least part of the inlet region, especially allowing the soot particles to be evenly deposited and the surface precipitator to be continuously regenerated.

    摘要： Honeycomb bodies, especially those used in an exhaust system of an internal combustion engine, contain a housing and a metal matrix with an average starting diameter. The matrix is connected to the housing, whereby at least one contraction limiter that causes an outward directed tensile stress in at least one part of the matrix is provided. The average starting diameter of the matrix is reduced by 5%, preferably by a maximum of 2%, during and/or after being subjected to thermal stress.

    摘要： A method for operating a particle trap, in particular an open particle trap, in an exhaust gas system of an internal combustion engine, includes determining a first point in time in which the particle trap falls below a first effectiveness limiting value, increasing the effectiveness of the particle trap by adjusting at least one specific operating parameter of the internal combustion engine, while exhaust gas produced by the internal combustion engine does not exceed a temperature of 500° C. in the vicinity of the particle trap, determining a second point in time in which the particle trap exceeds a second effectiveness limiting value, and activating normal operation of the internal combustion engine. The method and an associated device ensure operation of an exhaust gas system of an internal combustion engine, with conservation of fuel, savings of materials and simultaneous high effectiveness of the particle trap integrated into the exhaust gas system.
