摘要

The exhaust strand (10) has a mixing device (14) through which an exhaust gas flows for mixing with a reducing agent in an exhaust line. The size of a partial flow (28) of the exhaust gas is variable according to the flow rate. A pushing element (30) is provided for moving the mixing device by using a wall of the exhaust line.
