A SUPPORT BODY (1) IS DESCRIBED WHICH HAS AN ADSORBER MATERIAL (2) FOR ADSORBING NITROGEN OXIDES IN AN EXHAUST GAS WHICH IS GENERATED IN AT LEAST ONE COMBUSTION CHAMBER (3) OF AN INTERNAL-COMBUSTION ENGINE (4). A METHOD IS DESCRIBED FOR OPERATING AN INTERNALCOMBUSTION ENGINE (4) HAVING AN EXHAUST SYSTEM WHICH HAS A SUPPORT BODY OF THIS TYPE. ALL THE COMBUSTION CHAMBERS (3) OF THE INTERNAL-COMBUSTION ENGINE TOGETHER HAVE AN OVERALL COMBUSTION CHAMBER (5), AND THE SUPPORT BODY HAS AN ADSORBER VOLUME (6). THE ADSORBER VOLUME IS CONFIGURED TO BE LESS THAN 75%, IN PARTICULAR LESS THAN 45%, AND PREFERABLY EVEN LESS THAN 5% OF THE COMBUSTION CHAMBER VOLUME (5). A SUPPORT BODY (1) OF THIS TYPE ENSURES A GOOD COLD-STARTING PERFORMANCE OF THE EXHAUST SYSTEM (20) AND PREVENTS THE EMISSION OF NITROGEN OXIDES, IN PARTICULAR WHEN USING THE PROPOSED METHOD OF OPERATING THE EXHAUST SYSTEM (20).
