Abstract
In a method for adapting the reducing agent feed in an exhaust gas aftertreatment system having an SCR catalyst for removing nitrogen oxides from the exhaust gas of an internal combustion engine and at least one reducing agent feed device, the minimum opening time of the reducing agent feed device is determined during operation and while suspending nitrogen emission, carrying out the following steps: a) the opening time of the reducing agent feed device is gradually prolonged until b) a reducing agent-sensitive sensor in the exhaust gas aftertreatment system detects a reducing agent signal. An exhaust gas aftertreatment system is designed accordingly for carrying out the method and a device is designed for controlling an exhaust gas aftertreatment system.
