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： 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 (ΔP/GA) is greater than a correction reference value (Dp), the ECU adds a correction value corresponding to the exhaust pressure difference to the estimated accumulation amount. This causes the estimated accumulation amount to approach the actual accumulation amount.

摘要： In a fuel injection controller for a fuel injection system that executes an injection quantity learning operation for a fuel injection valve, a drive signal is outputted when the diagnosis condition is satisfied. An actual injection quantity of fuel that is actually injected by the fuel injection valve is computed. The fuel injection controller computes a correction amount based on a difference between the actual injection quantity and the command injection quantity. The fuel injection controller determines whether the correction amount exceeds a limit value. An injection deviation amount between the command injection quantity and the actual injection quantity of fuel, which is injected based on the drive signal corrected by the limit value, is computed when the correction amount exceeds the limit value.

摘要： An exhaust purifying apparatus for an internal combustion engine includes execution means, wherein, when an accumulation amount of particulate matter about a catalyst becomes less than a first determination value after a PM elimination control is started, the execution means executes burn-up control. Stopping means stops the PM elimination control based on an end of the burn-up control. Forcibly ending means forcibly ends the burn-up control when time elapsed since the accumulation amount of particulate matter about the catalyst has dropped to a second determination value reaches a predetermined time. Therefore, the exhaust purifying apparatus is capable of completely burning particulate matter in a PM filter, and suppresses degradation of fuel economy.

摘要： An exhaust purifying apparatus estimates an accumulation amount of particulate matter trapped about a catalyst in an exhaust system. When the estimated accumulation amount is equal to or more than a permissible value, the apparatus executes PM elimination control for supplying unburned fuel component to the catalyst. The apparatus sets the estimated accumulation amount to zero at the completion of the PM elimination control. When execution of the PM elimination control becomes possible after suspension of the control, the apparatus resumes the PM elimination control even if the accumulation amount is less than the permissible value. Therefore, The estimated accumulation amount is prevented from being significantly deviated from the actual accumulation amount due to suspension.

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.
