Abstract

An exhaust-gas system has an exhaust-gas pipe for guiding an exhaust-gas flow and an injection nozzle mounted to the exhaust-gas pipe for injecting reducing agent into the exhaust-gas flow. Downstream of the injection nozzle, the exhaust-gas pipe branches into at least two exhaust-gas lines. A fluid divider, formed with a front face that faces upstream into the gas flow, is disposed between the injection nozzle and the branching. The front face is oriented with respect to the cross section of the exhaust-gas pipe and the injection nozzle, such that the exhaust-gas flow and the medium are divided among the exhaust-gas lines in a predefined dividing ratio.
