摘要： A filter differential pressure, which is the difference between the inlet pressure and the outlet pressure of a DPM filter (11), is determined, and switching is performed in accordance with the regeneration condition of the DPM filter (11) between a first trapped DPM amount calculation process for estimating the trapped DPM amount after complete regeneration, in which all of the DPM trapped in the DPM filter (11) is burned, and a second trapped DPM amount calculation process for estimating the trapped DPM amount when a part of the DPM trapped in the DPM filter (11) has been burned away. The trapped DPM amount in the DPM filter (11) is estimated on the basis of the filter differential pressure using one of the first and second trapped DPM amount calculation processes.

摘要： A diesel particulate filter (41) traps particulate matter contained in the exhaust gas of a diesel engine (1) for a vehicle. The filter (41) is regenerated by raising the exhaust gas temperature so that the trapped particulate matter burns. A controller (31) calculates a particulate matter combustion amount PMr during regeneration, and in accordance with increases in the combustion amount PMr, raises the oxygen concentration of the exhaust gas by operating an intake throttle (42) and/or a variable nozzle (24) of a turbocharger (21). As a result, the filter (41) is held at an optimum temperature for regeneration regardless of the residual particulate matter amount, and hence the time required for regeneration can be shortened without damaging the heat resistance performance of the filter (41).

摘要： A diesel particulate filter (41) which traps particulate matter contained in the exhaust gas of a diesel engine (1) comprises an oxidation catalyst (41A) which exhibits a temperature-raising effect during regeneration of the filter (41). A controller (31) calculates the amount of particulate matter trapped in the filter (41) at the start of regeneration as a first amount, and calculates the amount of particulate matter burned during regeneration of the filter (41) as a second amount (S3, S10, S18). A deterioration factor d of the oxidation catalyst is calculated from the ratio of the second amount and first amount, and a target temperature for the next regeneration of the filter is determined on the basis of this deterioration factor d. Thus deterioration of the oxidation catalyst (41A) is compensated for, and an optimum temperature environment for regenerating the filter (41) is realized.

摘要： To regenerate a diesel particulate filter (10) which traps particulate matter contained in the exhaust gas of a diesel engine (20), a controller (16) raises the temperature of the exhaust gas through fuel injection control of a fuel injector (23), and thus burns the particulate matter trapped in the filter (10). The controller (16) cumulatively calculates the time during which the temperature of the filter (10) exceeds a target temperature as an effective regeneration time. By estimating the amount of particulate matter remaining in the filter (10) on the basis of the effective regeneration time, the controller (16) estimates the amount of remaining particulate matter with a high degree of precision and without consuming energy, whereupon regeneration of the filter (10) through fuel injection control ends.
