ABSTRACT:
A process and a system are used for controlling the mixture composition for an Otto engine with an NOxstorage catalyst during a regeneration phase. The process includes controlling, to the value of one, a λ-value (λM) of an exhaust gas fed to the NOxstorage catalyst during a regeneration phase as a function of a λ-value (λK) of an exhaust gas emitted by the NOxstorage catalyst. The system includes a control device for controlling, to the value of one, a λ-value (λM) of the exhaust gas fed to the NOxstorage catalyst during the regeneration phase as a function of the λ-value (λK) of the exhaust gas emitted by the NOxstorage catalyst.
