An exhaust gas line (1) of an internal combustion engine includes at least one catalytic converter (2) which is provided with at least one catalytic converter support (4) which is arranged in the housing (3) and which includes at least one first and one second area (5, 6) which can be flowed through
An exhaust gas line (1) of an internal combustion engine includes at least one catalytic converter (2) which is provided with at least one catalytic converter support (4) which is arranged in the housing (3) and which includes at least one first and one second area (5, 6) which can be flowed through in parallel, with the flow being capable of being deactivated in at least one area by a switching device (8) arranged in the exhaust gas line (1). In order to achieve a rapid activation of the catalytic converter in the simplest possible and most compact way, the areas (5, 6) of the catalytic converter support (4) have different physical and/or chemical properties in relation to response behavior, permeability, catalytic activity and/or thermal inertia.

1. A one-piece liquid-cooled cylinder head and liquid-cooled exhaust manifold comprising: a cylinder head defining a gasket surface for attachment to a cylinder block of an internal combustion engine, a first internal cooling chamber, a first inlet channel extending from said gasket surface to said first cooling chamber, and a first outlet channel extending away from said first cooling chamber,an exhaust manifold defining a second internal cooling chamber spaced from said first cooling chamber, a second inlet channel extending from said gasket surface to said second cooling chamber, and a second outlet channel extending away from said second cooling chamber, said second outlet channel connecting with said first cooling chamber, anda valve in one of said first inlet channel, said first outlet channel, said second inlet channel and said second outlet channel, said valve being selected from a thermostat valve and an electric switching valve, so that liquid flow through said first and second cooling chambers can be separately adjusted. 2. A one-piece liquid-cooled cylinder head and liquid-cooled exhaust manifold comprising: a cylinder head defining a gasket surface for attachment to a cylinder block of an internal combustion engine, a first internal cooling chamber, a first inlet channel extending from said gasket surface to said first cooling chamber, and a first outlet channel extending away from said first cooling chamber,an exhaust manifold defining a second internal cooling chamber spaced from said first cooling chamber, a second inlet channel extending from said gasket surface to said second cooling chamber, and a second outlet channel extending away from said second cooling chamber, anda thermostate valve in one of said first inlet channel, said first outlet channel, said second inlet channel and said second outlet channel, so that liquid flow through said first and second cooling chambers can be separately adjusted. 3. A one-piece liquid-cooled cylinder head and liquid-cooled exhaust manifold comprising: a cylinder head defining a gasket surface for attachment to a cylinder block of an internal combustion engine, a first internal cooling chamber, a first inlet channel extending from said gasket surface to said first cooling chamber, and a first outlet channel extending away from said first cooling chamber,an exhaust manifold defining a second internal cooling chamber spaced from said first cooling chamber, a second inlet channel extending from said gasket surface to said second cooling chamber, and a second outlet channel extending away from said second cooling chamber,a cylinder head gasket which provides a throttle opening at the second inlet channel, anda valve in one of said first inlet channel, said first outlet channel, said second inlet channel and said second outlet channel, said valve being selected from a thermostat valve and an electric switching valve, so that liquid flow through said first and second cooling chambers can be separately adjusted.
