Abstract: A playback mode operation process of the soot-particle filtering filter is provided to perform exact regeneration mode logic even when the number of rotation of the soot-particle filtering filter is changed. A playback mode operation process of the soot-particle filtering filter comprises a step(S51) which periodically reads an exhaustion pressure and an exhaustion flow for the predetermined time; a step(S53) producing the slope of X coefficient; and a step(S55) entering the playback mode after rising the discharge temperature.
