Abstract
The invention relates to a method for reactivating a system composed of an oxidation catalytic converter () followed by a possibly catalytically coated particle filter (), and to a correspondingly adapted exhaust-gas purification system for lean-burn engines () with low pressure EGR (). The present invention relates in particular to the reactivation of such a system during overrun operation of the engine.
