Method for rejuvenating a smoke filter which is adapted to remove solid particles from an internal combustion engine exhaust gas stream. The filter includes a bed which forms a multi-passage path along which an exhaust stream flows, and in which carbon particles are retained. A heating element incorporated into the filter bed periodically heats the flowing exhaust gas stream as well as the bed. Rejuvenation of the bed by burning off carbon is regulated in response to variations in the gas pressure, and in the bed temperature.
