Method and apparatus for monitoring a reductant solution composition in the exhaust system of an internal combustion engine |
abstract |
In a method and apparatus for monitoring a reductant solution composition in the exhaust system (1) of an internal combustion engine (2) with metered injection of the reductant solution upstream of an SCR catalyst (7), metered injection of the reductant solution into the exhaust stream and quantitative determination of a consequent change occurs the water content in the exhaust stream, preferably by measurement with a broadband oxygen sensor (12). With knowledge of the injected volume flow, it is possible to deduce the actual urea content of the reducing agent solution from the sensor signal, so that deviations from the standard composition during metering can be taken into account or indicated as errors. |
