摘要： 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.

摘要： A filter (41) traps particulate matter in the exhaust gas of a vehicle diesel engine (1).A vehicle speed sensor (51) detects a vehicle speed, and a controller (31) determines a vehicle running pattern from the vehicle speed. In the regeneration of the filter (41) to eliminate trapped particulate matter by burning, the controller (31) controls the exhaust gas temperature of the diesel engine (1) to a different target temperature according to the running pattern. As a result, there are less opportunities for regeneration of the filter (41) to be interrupted due to exhaust gas temperature drop, and regeneration of the filter (41) is ensured.

摘要： A regeneration control device which regenerates a filter (13) by increasing an exhaust gas temperature to burn exhaust gas particulates trapped in the filter, is disclosed. The filter (13) traps particulate matter in exhaust gas from an engine (1). The regeneration control device suppresses fuel cost-performance impairment due to filter regeneration. The regeneration control device has a load detection sensor (31) which detects an engine load and a microcomputer-based controller (22). The controller is programmed to perform engine control to adjust the exhaust gas temperature for regeneration of the filter (13), when a computed trapped amount is equal to or more than the first reference value (A) and less than the second reference value (B), and the detected load (Vsp) is equal to or more than a reference load (Vo); and perform engine control to adjust the exhaust gas temperature for regeneration of the filter (13) regardless of the detected load (Vsp), when the computed trapped amount is equal to or more than the second reference value (B).
