The invention relates to an exhaust gas after-treatment component (26), comprising a ceramic carrier (30) having a plurality of axial flow channels (32), wherein the carrier (30) has an inner region (34) and an outer region (36) that radially surrounds the inner region (34) and a cell density of the carrier (30) in the inner region (34) is lower than a cell density thereof in the outer region (36), and at least the outer region (36) of the carrier (30) has a coating and the coating of the outer region (36) has an HC adsorber function for reversibly adsorbing unburnt hydrocarbons (HC). The invention further relates to an exhaust system (10) that is provided with such an exhaust gas after-treatment component (26) and to a motor vehicle that comprises such an exhaust system (10). |
