Beschreibung
Zusammenfassung:	An exhaust gas aftertreatment component includes a ceramic carrier body with a plurality of axial flow channels, wherein the carrier body has an inner region and an outer region, which radially surrounds the inner region. A cell density of the carrier body is smaller in the inner region than a cell density in the outer region. At least the outer region of the carrier body has a coaling, wherein the coating of the outer region has an HC adsorber function for a reversible adsorption of unburnt hydrocarbons. An exhaust gas system, which is equipped with such an exhaust gas aftertreatment component, and a vehicle, which has such an exhaust gas system are also provided.
