A method of operating an exhaust aftertreatment system of an internal combustion engine, exhaust aftertreatment system for an internal combustion engine and internal combustion engine with such an exhaust aftertreatment system

摘要

A method for operating an exhaust aftertreatment system (3) of an internal combustion engine (1) is proposed, wherein during operation of the exhaust aftertreatment system (3) at least one operating parameter is detected that is related to an oxidation state of an SCR catalyst material of the exhaust aftertreatment system (3) depending on the at least one operating parameter at least one measure for preventing a progressive reduction of the SCR catalyst material and / or at least one Reoxidationsmaßnahme for reoxidation of the SCR catalyst material is initiated.
