Abstract

A method for enriching the exhaust gas of an internal combustion engine with a reducing agent is provided, the internal combustion engine including at least one cylinder and having an intake system for admission of charge air, an exhaust gas discharge system for discharging exhaust gases, and at least one exhaust gas aftertreatment system for reducing nitrogen oxides arranged in the exhaust gas discharge system and which is periodically provided with a supply of reducing agent. The method comprises enriching the exhaust gas with the reducing agent in the exhaust gas discharge system upstream of at least the one exhaust gas aftertreatment system when a fuel supply of the at least one cylinder of the internal combustion engine is deactivated due to an absence of load demand.
