摘要： In an exhaust emission purification method and an exhaust emission purification system where forced regeneration start timing of a DPF for purifying the PM (particulate matters) in exhaust gas is judged based on the comparison of a differential pressure across the DPF with a predetermined differential pressure threshold across the DPF, a differential pressure threshold (ΔPs) across the DPF is set by multiplying a reference differential pressure threshold (ΔPs0) across the DPF by a coefficient (α(ΔM)) which varies stepwise or continuously depending on the mileage (ΔM) of a vehicle after previous forced regeneration. Consequently, the PM can be removed by burning while the amount of PM accumulated unevenly in the DPF is still small, and excessive temperature rise in the DPF resulting from excessive accumulation of PM during forced regeneration and melting-loss of DPF due to excessive temperature rise can be prevented.

摘要： Detected first is fluctuation of engine revolution speed that varies with torsional vibration occurring in a drive train when the vehicle is acceleratedldecelerated. A basic amount of fuel injection (Qbase) is determined from an accelerator opening (APS) and engine revolution speed (RPM). An intermediate value (Qbad), which is an amount of fuel needed at the time of drive power being first transmitted to drive wheels from an engine, is determined from water temperature (Tw) and engine revolution speed (RPM). A difference (Qabs) is calculated by subtracting the intermediate value (Qbad) from the basic value (Qbase). A correction value (Qacl2) to counterbalance the fluctuation of the engine revolution speed (RPM) is then determined based on the difference (Qabs), engine revolution speed (RPM), engine revolution speed change (&Dgr;RPM) and/or its differential value (D&Dgr;RPM). A target amount of fuel injection (Qfnl) is sequentially increased/decreased in accordance with the correction value (Qacl2), thereby attenuating the torsional vibration.

摘要： A first sensor detects whether an engine revolution speed change exceeds a predetermined amount, and a second sensor detects whether an accelerator opening stays within a predetermined range. A controller determines a target amount of fuel injection that is greater than a basic amount of fuel injection when the engine revolution speed change exceeds the predetermined amount and the accelerator opening stays in the predetermined range. The basic amount of fuel injection is determined based on the accelerator opening and engine revolution speed. By feeding a slightly larger amount of fuel than the basic value while an engine brake is applying, the engine revolution speed change is suppressed and shock upon clutch engagement is reduced.

摘要： Forced regeneration start timing of a diesel particulate filter for purifying particulate matter in exhaust gas is judged based on a comparison of a differential pressure across the diesel particulate filter with a predetermined differential pressure threshold across the filter. The predetermined differential pressure threshold is set by multiplying a reference differential pressure threshold by a coefficient which varies stepwise or continuously depending on a mileage of a vehicle after previous forced regeneration. Consequently, particulate matter can be removed by burning while the amount of particulate matter accumulated unevenly in the filter is still small, and excessive temperature rise in the filter resulting from excessive accumulation of particulate matter during forced regeneration and melting-loss of the filter due to excessive temperature rise can be prevented.

摘要： An exhaust emission purification system including a controller performing exhaust temperature rise control executing multistage delay injection control for raising the exhaust temperature, if the exhaust gas temperature is lower than a predetermined judgment temperature, and performing particulate matter combustion removal control executing post injection control, if the exhaust gas temperature becomes equal to or higher than the predetermined judgment temperature, when forced regeneration of a diesel particulate filter is carried out. Multistage delay injection control is forbidden when an idle operation state of an internal combustion engine is sustained for a predetermined judgment time and a power take-off is in operating state. The diesel particulate filter is thereby kept in a good state in a vehicle equipped for purifying particulate matter in exhaust gas by executing forced regeneration while avoiding variation in engine speed.
