Exhaust gas treatment arrangement for internal-combustion engine, has exit gas line, where exit gas line has unit for producing pressure difference

摘要

The exhaust gas treatment arrangement (5) has an exit gas line (25), where the exit gas line has a unit for producing pressure difference. A bypass path (27) is arranged such that a partition of the exhaust gas flow is provided between the exit gas line and the bypass path by an electronic-control-free medium (30) at an operation of an internal-combustion engine (10). The unit has a turbine (15) of a supercharger (12).
