A device is provided for the distribution of flowable additives in exhaust gas systems of an internal combustion engine, in particular for the distribution of a water/urea mixture in an exhaust gas system of a diesel engine, having an injection device in particular opening into the exhaust tract before a so-called SRC catalytic converter, with a swirl generation device being provided for the improvement of the mixing of the exhaust gas with the additive in the introduction region of the additive in the exhaust tract.

Device for the distribution of flowable additives in exhaust gas systems

A system assembly detects the amount of reducing agent and the amount of pollutant in an exhaust gas. The system assembly has a first pollutant sensor, which is cross-sensitive to the reducing agent, and is provided for emitting a first measuring signal proportional to the amount of pollutant in the exhaust gas for use in front of a filtering device for the selective reducing of the reducing agent or the pollutant in the exhaust gas. A second pollutant sensor, which is also cross-sensitive to the reducing agent, emits a second measuring signal proportional to the amount of pollutant in the exhaust gas for use behind the filtering device.
