METHOD AND SYSTEM FOR REGENERATING AN EXHAUST GAS PURIFICATION UNIT.

摘要

The invention concerns a method for regenerating an exhaust gas purification unit (13) arranged in an internal combustion engine system (1). The invention is characterized "in that the method comprises the step of setting a predefined minimum engine speed such that the exhaust gas mass flow exceeds a predefined flow value during the regeneration process. The invention also concerns an internal combustion engine system (1 ) comprising an exhaust gas purification unit (13) adapted to be operated according to said method.
