摘要：The method involves producing hot exhaust gas flow (16') such that anotherexhaust gas flow (16) to be heated is diverted from a raw exhaust gas (15) to a branch-off
point (6) upstream to a particulate filter (3). The diverted gas flow is heated by a heatingcatalyzer (8) i.e. oxidation catalyzer, and supplied as the hot gas flow to the raw exhaustgas (15') downstream to the point and upstream to the filter at an orifice (7). A fresh airflow is supplied to the exhaust gas flow to be heated after reaching a preset heatingtemperature measured at the hot gas flow and/or a preset lambda value. An
independent claim is also included for a device for regenerating a particulate filter builtinto an exhaust section of an internal combustion engine.
