Abstract

A method for evaluating an effective component content (C) of a reducing agent for engine exhaust gas processing arranged in a container () in which a heat transfer provision arrangement () is provided, including steps of: determining (s; s) a prevailing volume (V) and temperature (T) of the reducing agent in the container (); determining (s) a prevailing temperature (T) of the heat transfer provision arrangement (); determining (s) a prevailing temperature (T) of a medium surrounding the container (); for a predetermined time period, determining (s) a mean temperature change rate (Tprim) for the reducing agent; and determining (s) the effective component content (C) of the reducing agent on the basis of the above determined parameters.
