<p>Regeneration of a particle filter integrated into the exhaust pipe from an internal combustion engine. The temperature is monitored by sensors between the entry surface and exit surface in at least two zones during regeneration. The exhaust gas temperature is monitored by sensors upstream and downstream of the filter. The temperature can be monitored at entry, exit, and in the center of the filter. - For the regeneration of a particle filter (10), integrated into the exhaust pipe (12) from an internal combustion engine, the temperature is monitored by sensors (24,26,28) between the entry surface (16) and exit surface (18) in at least two zones during regeneration. The exhaust gas temperature is also monitored by a sensor (30) upstream of the filter, and a sensor (32) downstream of it The temperature can be monitored at the entry, exit, and in the center of the filter. The oxygen level in the exhaust gas (14) is reduced at a monitored temperature which is above a critical level. The oxygen level is increased in the exhaust gas at the monitored temperatures which are below the critical level. The oxygen levels are reduced or increased by running the engine with rich or lean fuel mixtures.</p> |
