Abstract

Methods and systems are provided for regenerating a NOx storage catalytic converter of a multi-cylinder internal combustion engine comprising selectively switchable cylinders. During permissible engine operating conditions, the switchable cylinders may be deactivated in order to regenerate the NOx storage catalytic converter using the rich exhaust from the active cylinders blended with un-combusted gas from the deactivated cylinders.
