摘要： An adding time a of a fuel addition to an exhaust system is limited to a guard value G or less during an adding period A of a concentrated intermittent fuel of a catalyst recovery control. Accordingly, a one-time fuel adding amount from an adding valve 46 is limited to be equal to or less than a predetermined value, and it is possible to prevent such a great amount of unburned fuel component that cannot be fully purified by a NOx catalyst from being supplied to the NOx catalyst during the adding period A. Further, if a total amount (GF+Q1)·t of the unburned fuel component supplied to the NOx catalyst during the adding period A reaches an allowable upper limit value UL, the concentrated intermittent fuel addition is canceled and a suspend period B is forcibly started. Accordingly, it is possible to prevent a total amount of such a great amount of unburned fuel component that cannot be fully purified by the NOx catalyst from being supplied to the NOx catalyst during the adding period A. Therefore, generation of white smoke in exhaust gas of the internal combustion engine by an excessive supply of the unburned fuel component to the NOx catalyst at a time of executing catalyst recovery control can be prevented.

摘要： A regeneration controller for an exhaust purification apparatus (36, 38) of an engine (2) that appropriately burns particulate matter accumulated in the exhaust purification apparatus. The regeneration controller includes an ECU (70) that determines whether an estimated accumulation amount (PMsm) of particulate matter deviates from an actual accumulation amount. When the estimated accumulation amount is less than or equal to a maximum value (BUpm) and an exhaust pressure difference (&Dgr;P/GA) is greater than a replacement reference value (Dp), the ECU replaces the estimated accumulation amount with a greater replacement amount (UPpm). This causes the estimated accumulation amount to approach or to be the same as the actual accumulation amount.

The DPNR converter (26) is located in an exhaust passage (14) of the internal combustion engine (10). The DPNR converter (26) traps particulate matter in exhaust gas. The fuel adding device (46) adds fuel to exhaust as that passes through the DPNR converter (26).

摘要： In an exhaust purifying apparatus, a fuel adding valve (31) supplies unburned fuel to an exhaust passage (14) of a diesel engine (10) so that particulate matter collected in a catalytic converter (33) is burned and removed. The supply of unburned fuel from the fuel adding valve (31) is executed even after an electronic control unit (41) determines that particulate matter in the catalytic converter (33) has been burned and removed. This reduces the amount of particulate matter remaining unburned in the catalytic converter (33).

摘要： An exhaust purifying apparatus for an internal combustion engine includes an exhaust purifying mechanism, a fuel adding device, an electronic control device. The exhaust purifying mechanism is located in an exhaust passage and traps particulate matter. The fuel adding device adds fuel to exhaust gas that passes through the mechanism. The electronic control device detects a pressure difference between a section upstream and a section downstream of the exhaust purifying mechanism. While the fuel adding device is adding fuel to exhaust gas, the electronic control device compares the pressure difference that is detected at a predetermined point in time with the pressure difference reference value. When the pressure difference exceeds the pressure difference reference value, the electronic control device sets the manner of adding fuel to intermittent fuel addition. As a result, the exhaust purifying apparatus decreases the amount of particulate matter that remains in the exhaust purifying mechanism.
