Abstract: This invention relates to estimation of a particulate matter deposit amount in a diesel particulate filter (1) provided in an exhaust passage (7) of a vehicle diesel engine (10). When the vehicle speed exceeds a predetermined vehicle speed, a differential pressure method, in which the particulate matter deposit amount is estimated based on the differential pressure upstream and downstream of the filter (1), is applied, and when the vehicle speed does not exceed the predetermined vehicle speed, an accumulation method, in which the particulate matter deposit amount is estimated by accumulating an increment determined from the load and rotation speed of the diesel engine (10), is applied. When switching from the differential pressure method to the accumulation method, the particulate matter deposit amount determined in the differential pressure method is used as an initial value of the accumulation, and thus the particulate matter deposit amount can be determined accurately.

Abstract: A map which defines a relationship of an exhaust gas pressure P2 at the outlet of a filter (13) to a load Q and rotation speed Ne of an engine (1) is prepared, and an exhaust gas pressure P1 at the inlet to the filter (13) is determined from a differential pressure ΔP between the front and rear of the filter and the outlet pressure P2 obtained by referring to the map. The inlet pressure P1 determined in this manner is used to determine an exhaust gas volumetric flow rate Q1, and thus an accurate particulate accumulation SM, which is required to determine the need for regeneration of the filter (13), can be calculated.

Abstract: 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.

Abstract: 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.
