<p>The exhaust system comprises an exhaust duct (7), a catalytic converter (8) for selective catalytic reduction, a mixing duct (12), and a mixer (10) that is connected to the mixing duct (12) for receiving a partial exhaust gas stream and reducing agent and releasing the mix- ture of the exhaust gas and the reducing agent into the mixing duct (12). The mixer (10) is a venturi mixer comprising a first duct section (10A) with a first cross- sectional area, a second section (10B) with a second cross-sectional area, and a third section (10C), which is arranged between the first and the second sections (10A, 10B) and has a third cross-sectional area, which is smaller than the first and the second cross-sectional areas.</p> |
