A method and a device for the addition in droplet form of a liquid reducing agent to an exhaust gas line of an internal combustion engine, particularly to a rear end side of an exhaust gas treatment component, includes at least identifying at least one exhaust gas parameter during operation of the internal combustion engine, determining a size of a droplet of the reducing agent to be added as a function of an exhaust gas parameter, adjusting a first delivery pressure of the reducing agent toward the exhaust line as a function of the determined size of the droplet, and adding the reducing agent to the exhaust line with an adding unit. In this way, it can be achieved, in particular, that the end side of the exhaust gas treatment component is evenly wetted during operation of the internal combustion engine by using the droplets of the reducing agent. |
