Abstract
In a method for monitoring an SCR catalyst, in particular for monitoring the storage capacity of the SCR catalyst for ammonia, superstoichiometric metering () of reducing agents into the SCR catalyst is performed for diagnostic purposes, and the storage capacity of the SCR catalyst is inferred in accordance with at least one characteristic value, which is dependent on the nitrogen oxide conversion rate of the SCR catalyst. In this method, a conditioning phase () for setting a specifiable operating point () is carried out before the superstoichiometric metering () of reducing agents.
