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.

An exhaust gas system for diesel vehicles has a first exhaust line and a second exhaust line that can be connected at the exhaust end to an engine. The first and second lines with their ends pointing downstream are connected to an SCR catalytic converter and a device with which a reducing agent can be introduced into the exhaust gas at a location situated upstream from the SCR catalytic converter. An injection unit for the reducing agent is provided only on the first exhaust line, and a mixing device is provided upstream from the SCR catalytic converter so that the exhaust lines open into the mixing device, where the exhaust gas stream of the first exhaust line to which the reducing agent has been added becomes mixed with the exhaust gas stream from the second exhaust line that is free of reducing agent.
