METHOD AND DEVICE FOR REACTIVATING EXHAUST-GAS PURIFICATION SYSTEMS OF DIESEL ENGINES WITH LOW-PRESSURE EGR

摘要

The invention relates to a method for reactivating a system composed of an oxidation catalytic converter (5) followed by a possibly catalytically coated particle filter (6), and to a correspondingly adapted exhaust-gas purification system for lean-burn engines (1) with low pressure EGR (14). The present invention relates in particular to the reactivation of such a system during overrun operation of the engine.
