摘要： The invention relates to a method for regenerating an emission control system of an internal combustion engine, comprising a storage catalytic converter, a first exhaust gas probe being situated in an exhaust gas tract upstream of the storage catalytic converter and a second exhaust gas probe being situated in a second exhaust gas tract downstream of the storage catalytic converter. A first output signal of a first exhaust gas probe and a second output signal of a second exhaust gas probe are supplied to an engine management system and the storage catalytic converter is regenerated by being exposed to a reductant in a regeneration phase. If the quantity of reductant is controlled by the engine management system during the regeneration phase, whereby said system detects the quantity of reductant that is present downstream of the storage catalytic converter by means of the second output signal of the second exhaust gas probe situated downstream of said converter, the charging of reductant can be significantly reduced with respect to an optimised dosage. Excess consumption of fuel or reductant as a result of the regeneration of the storage catalytic converter is minimised. In addition, the method improves the emission values, thus significantly contributing to the maintenance of emission limits.
