Apparatus and method for regenerating a particulate filter in the exhaust system of an internal combustion engine |
摘要 |
A particulate deposit amount Spm on a particulate filter (3) disposed in an exhaust passage (17) is estimated during a usual period other than a regeneration period of the particulate filter (3) and during the regeneration period thereof respectively. <??>An increase value Dpm per unit time of the Spm during the usual period is estimated based upon an engine operating condition and a sum of the Spm is determined by integration thereof (S15,16). <??>On the other hand, a particulate deposit amount Spm decreasing by burning during the regeneration period is determined by, one by one, subtracting a decrease value Dpm per unit time estimated based upon a particulate deposit amount Spmi that is determined by the above integration at a starting point of the regeneration period from the Spmi (S12,17). <IMAGE> |
