摘要： A method positions a sensor in a honeycomb body which is provided with hollow spaces that can be penetrated at least in part by an exhaust gas. The sensor is placed in an area of the honeycomb body in which at least one minimum hydrogen concentration occurs when the honeycomb body is operated in the emission system of a motor vehicle. The sensor positioning method allows the sensor to be placed in the honeycomb body in such a way that systematic errors that occur are kept as small as possible as a result of an inherent transverse sensitivity of the sensor to hydrogen. This applies especially to lambda probes. A honeycomb body contains the sensor which is placed so as to supply particularly reliable test data whose systematic error is as small as possible.

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.
