The method involves producing hot exhaust gas flow (16') such that another exhaust 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 heating catalyzer (8) i.e. oxidation catalyzer, and supplied as the hot gas flow to the raw exhaust gas (15') downstream to the point and upstream to the filter at an orifice (7). A fresh air flow is supplied to the exhaust gas flow to be heated after reaching a preset heating temperature 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 built into an exhaust section of an internal combustion engine. |
