Abstract
A method and to a device for the regeneration of a particle arranged in the exhaust gas train of an internal combustion engine. An exhaust gas stream to be cleaned is supplied to the at least one particle filter. At least in a regeneration mode, a predetermined amount of an exhaust gas stream to be heated is branched off from the exhaust gas stream upstream of an exhaust gas turbine of an exhaust gas turbocharger which branched-off stream, after it has been heated by a heater is mixed in the form of a heated exhaust gas stream at a point upstream of the at least one particle filter back into the residual gas stream which is coming from the exhaust gas turbine and which is at a lower temperature than that of the other stream.
