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.

Exhaust gas line of an internal combustion engine

The present invention relates to an internal combustion, reciprocating pin engine with a piston which, on its up-stroke, sucks air or a fuel-air mixture via a flap valve or a similar device into the space beneath its base and, during the down-stroke, sends the then compressed gas via another flap valve or a similar device and a connecting passage to the inlet control ports of said internal combustion, reciprocating piston engine. The pump space of the piston pump which is formed by piston, cylinder liner and annular slide comprises an inlet passage and an outlet passage, equipped with diaphragm valves, respectively. The crankcase, having a cross-section of mainly circular form, is equipped with a rotatable annular slide, which is carried on bearings and into which, with a small amount of clearance, the connecting rod extends, the latter having uniform dimensions in the direction of the axis of the crankshaft at least in the area enclosed by said annular slide, to form a suction chamber A and a pressure chamber B of a separated connecting-rod pump within said annular slide. A large waste space formed by the crankcase can thus be avoided.
