    Abstract: A device for the aftertreatment of exhaust gases in an exhaust gas system of internal combustion engines, having at least one reductant decomposition catalyst. Arranged in the exhaust gas flow, and a metering device arranged upstream of the latter in an exhaust gas line for supplying reductant. Preferably at least one other catalyst device is provided downstream of the reductant decomposition catalyst. An inlet section for the exhaust gas having at least one flow deflection area is arranged upstream of the reductant decomposition catalyst and constructed for the exhaust gas to be fed into a housing radially outside an inlet pipe adjoining the reductant decomposition catalyst that encloses the inlet pipe, and is guided in counterflow through a front inlet opening of the inlet pipe to the reductant decomposition catalyst. The reductant is fed into the flow deflection area associated with the inlet opening.

    Abstract: A method and to a device for the regeneration of a particle filter arranged in the exhaust gas tract of an internal combustion engine with at least one NO oxidation catalyst for the oxidation of NO, especially to NO2, which is arranged upstream of the particle filter and through which an exhaust gas stream flows. At least one heater, especially a heating catalyst, through which another gas stream, i.e., a second exhaust gas stream, flows and which heats the additional gas steam, is provided upstream of the particle filter. The heated additional gas stream is mixed upstream of the particle filter with the exhaust gas stream coming from the NO oxidation catalyst, i.e., the gas stream loaded in particular with NO2.

    Abstract: A particle separator and method for removing particles from an exhaust gas stream of an internal combustion engine. A prescribed number of flow cells are formed in the particle separator. The exhaust gas stream flows into and/or out of the flow cells via, as viewed in a main direction of flow of the exhaust gas stream, side wall regions of the flow cells. At least one storage space is formed in the flow cells for storing particles removed from the exhaust gas stream, which flows through at least portions of the particle separator.

    Abstract: A device for reducing the emission of polychlorinated dibenzodioxins (PCDD) and polychlorinated dibenzofurans (PCDF) from transition metal-containing catalyzers for selective catalytic reduction of nitric oxides in the exhaust gas of an internal combustion engine by means of ammonia and/or reducing agents which split off ammonia. At least one catalyzer for oxidizing hydrocarbon-containing PCDD precursor substances and PCDF is arranged upstream of the at least one transition metal-containing SCR catalyzer and/or at least one catalyzer for degrading precursor substances for degrading the polychlorinated dibenzodioxins and/or polychlorinated dibenzofurans is arranged downstream of the at least one transition metal-containing catalyzer. The at least one catalyzer for degrading PCDD and PCDF and/or the at least one catalyzer for oxidizing hydrocarbon-containing precursor substances thereof are/is additionally active for the reduction of nitric oxides by means of ammonia.
