ABSTRACT:
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.
