Abstract:
A method and a device for the regeneration of a particle filter, especially a diesel particle filter, arranged in the exhaust gas train of an internal combustion engine, wherein an exhaust gas stream to be cleaned is supplied to the at least one particle filter. The exhaust gas stream supplied to the at least one particle filter is a raw exhaust gas stream of the internal combustion engine, into which, during regeneration mode, a heated exhaust gas stream at a higher temperature than the raw exhaust gas stream is mixed at a point upstream of the particle filter under the control of at least one open-loop and/or closed-loop control device, which actuates a throttle device and/or shut-off device in accordance with predetermined regeneration parameters.
