Abstract

A method for exhaust-gas aftertreatment of an exhaust gas (11) leaving an internal combustion engine (10), wherein the exhaust gas (11) is guided across a rotating particle filter (12) in such a way that the exhaust gas (11) flows through a part or section of the filter medium rotated into the exhaust gas flow, and the exhaust gas (11) does not flow through a part or section of the filter medium rotated out of the exhaust gas flow, wherein the part or section of the filter medium, which is rotated out of the exhaust gas flow, is initially regenerated inside of the rotating particle filter (12) in a first subchamber (14) of the rotating particle filter (12) located outside of the exhaust flow by oxidizing the soot in the filter medium, that subsequent to this regeneration, ash is removed from the part or section of the filter medium rotated out of the exhaust flow in a second subchamber (15) of the rotating particle filter (12) located outside of the exhaust gas flow, and that, subsequent to the regeneration and ash removal, the or section of the filter medium, rotated out of the exhaust gas flow, is rotated into the exhaust gas flow.A method for exhaust gas aftertreatment of an exhaust gas (11) leaving an internal combustion engine (10), wherein the exhaust gas (11) is guided across a rotating particle filter (12) in such a way that the exhaust gas (11) ) flows through a part or section of the filter medium rotated into the exhaust gas flow, and the exhaust gas (11) does not flow through a part or section of the filter medium rotated out of the exhaust gas flow, wherein the part or section of the filter medium, which is rotated out of the exhaust gas flow, is initially regenerated inside of the rotating particle filter (12) in a first subchamber (14) of the rotating particle filter (12) located outside of the exhaust flow by oxidizing the soot in the filter medium, that subsequent to this regeneration, ash is removed from the part or section of the filter medium rotated out of the exhaust flow in a second subchamber (15) of the rotating particle filter (12) located outside of the exhaust gas flow, and that, subsequently nt to the regeneration and ash removal, the or section of the filter medium, rotated out of the exhaust gas flow, is rotated into the exhaust gas flow.
