Abstract: A particle filter for an internal combustion engine has a filter body (2) with a first channel (5) having a first end (7) facing a filter inlet (3) and a second end (8) facing a filter outlet (4), and a flow-through second channel (6) having a third end (9) facing the filter inlet (3) and a fourth end (10) formed facing the filter outlet (4). The second and third ends (8, 9) cannot accommodate flow therethrough. The channels (5, 6) are divided into a flow-through section (13) and a non-flow-through section (14). A wall (11) between the channels (5, 6) enables soot particles to be separated from exhaust gas flowing through the filter body (2) from the first channel (5) into the second channel (6). The non-flow-through channel section (14) has a heating element (15) to increase a reaction temperature in the filter (1) for burning off the soot particles.

Abstract: In a method for monitoring an exhaust gas purifying component with gas storage capability for purifying exhaust gases from an internal combustion engine, the exhaust gas purifying component comprises a gas storage material which changes from a first state into a second state upon storage of the gas. A temperature change of the exhaust gas purifying component and/or of the gas storage material, substantially based on a heat tonality of the modification transition, is measured and evaluated.

Abstract: A component for cleaning the exhaust gas in an internal combustion engine has a carrier body with a plurality of flow ducts for the exhaust gas. At least some of the walls (3) of the flow ducts have a coating with an oxygen storage capacity. According to the invention, the coating with an oxygen storage capacity is provided for a first delimited region of the carrier body, while a second delimited region of the carrier body is made free of a coating with an oxygen storage capacity or has a coating with a greatly reduced oxygen storage capacity compared to the first region.
