Abstract
An exhaust gas line () of an internal combustion engine includes at least one catalytic converter () which is provided with at least one catalytic converter support () which is arranged in the housing () and which includes at least one first and one second area () which can be flowed through in parallel, with the flow being capable of being deactivated in at least one area by a switching device () arranged in the exhaust gas line (). In order to achieve a rapid activation of the catalytic converter in the simplest possible and most compact way, the areas () of the catalytic converter support () have different physical and/or chemical properties in relation to response behavior, permeability, catalytic activity and/or thermal inertia.
