ABSTRACT:
In an exhaust gas purifying apparatus for a diesel engine having a diesel particulate filter (DPF) provided in an exhaust pipe, a temperature of the DPF is indirectly detected (presumed) to prevent an over-heat of the DPF during a re-generation operation thereof. For that purpose, the DPF is hypothetically divided into multiple cells, the temperature at the respective cells is presumed based on a heat budget of the cell, and the maximum temperature among those multiple presumed temperatures is controlled to be lower than a predetermined value.
