摘要： A particulate matter deposit amount accumulated in a diesel participate filter (4) is calculated as a first particulate matter deposit amount from a pressure loss of the filter (4) (S33). The particulate matter deposit amount accumulated in the filter (4) is calculated as a second particulate matter deposit amount from another parameter (S34). It is determined whether or not there is front end blockage of the filter (4) based on a comparison between the first particulate matter deposit amount and second particulate matter deposit amount (S36, S43). When there is a front end blockage of the filter (4), the regeneration device is controlled to perform regeneration of the filter (4) for a longer period than the normal regeneration period of the filter (4) (S22).

摘要： A regeneration control device which regenerates a filter (4) which traps particulate matter in the exhaust gas of an engine (1) is disclosed. The regeneration control device includes a first temperature sensor (16, 17), which detects one of an upstream temperature and a downstream temperature upstream and downstream of the filter (4) as a first temperature (Tin, Tout); a second temperature sensor (16, 17), which detects the other temperature as a second temperature (Tin, Tout); and a microcomputer. The microcomputer programmed to compute an estimated value (Tbede2) for the second temperature based on the first temperature detected by the first temperature sensor (16, 17), compute an estimated bed temperature (Tbed2) of the filter based on the second temperature detected by a second temperature sensor (16, 17) and the estimated value (Tbede2) for the second temperature, and perform engine control for increasing the temperature of the exhaust gas based on the estimated bed temperature (Tbed2).

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) controls the fuel injector (23) to raise the temperature of the exhaust gas to a higher temperature as the amount of particulate matter trapped in the filter (10) decreases, thereby realizing effective regeneration while preventing the temperature of the filter (10) from becoming excessively high.

摘要： A controller (70) controls regeneration of an exhaust gas filter (52) which traps particulate matter contained in exhaust gas to prevent the particulate matter from being discharged into the atmosphere. When regeneration of the exhaust gas filter (52) is underway and the engine (10) is decelerating, the controller (70) determines whether or not a catalyst (40) is active (S82) and whether the engine (10) is decelerating gently or rapidly (S83). When the engine (10) is decelerating gently, the controller (70) performs a post-injection following a main fuel injection (S824), and when the engine (10) is decelerating rapidly, the controller (70) performs the main fuel injection but stops the post-injection (S834). In so doing, the temperature of the filter does not rise excessively, and the filter can be prevented from melting.

摘要： A particulate filter (41) which traps particulate matter in the exhaust gas of a diesel engine (1), regenerates when a controller (31) performs an exhaust gas increase operation which includes decreasing the opening of an intake throttle (42). The controller (31), during regeneration of the filter (41), determines whether or not the required load of the diesel engine (1) is increasing from an accelerator pedal depression sensor (32) or a fuel injection amount (S3), and prevents output decrease of the diesel engine (1) by interrupting the exhaust gas temperature increase operation when the required load is increasing (S5).
