Abstract

A method for regenerating an exhaust gas purification unit arranged in an internal combustion engine system includes setting a predefined minimum engine speed such that the exhaust gas mass flow exceeds a predefined flow value during the regeneration process. An internal combustion engine system including an exhaust gas purification unit adapted to be operated according to the method is also provided.
