The invention describes a device for supplying a reducing agent (22), e.g. urea, to an exhaust line (10) of a combustion engine (101 ). Before the reducing agent (22) is supplied to the exhaust line (10), carbon dioxide is added (29, 30, 31). A very turbulent flow of reducing agent is thus formed in the exhaust line and the problem of urea lumps in the exhaust line (10) is diminished. The invention relates to an engine with such a device and to a vehicle with such an engine. |
