摘要： Even in the case of driving for a long time in the low rotation speed driving condition in which the exhaust flow rate is small and an estimation of the PM accumulated amount due to the pressure difference between the front and the back sides of a filter is difficult, the forced regeneration time can be accurately judged, the deterioration of fuel efficiency that is caused by excessive PM trapping can be avoided, and at the same time, thermal runaway that is generated by the excessive accumulated amount of PM and melting damage of the DPF due to this thermal runaway can be prevented. In the exhaust gas purification system 1 that performs a forced regeneration control by judging a forced regeneration starting time of the DPF 12b from the pressure difference ΔPm between the front and the back sides of the DPF 12b, in the case of detecting that the driving condition of the internal combustion engine 10 is a low rotation speed driving condition, the sustaining time tm of the low rotation speed driving condition is measured, and when the measured sustaining time tm exceeds the predetermined time for judgment tc, the forced regeneration control of the DPF 12b is performed without affecting the pressure difference ΔPm between the front and the back sides of the DPF 12b.

By this arrangement, at forced regeneration of the DPF (12b), the unburned fuel supplied into an exhaust gas is surely oxidized and generation of white smoke is prevented regardless of an operation state of an internal combustion engine (10).

摘要： In in-cylinder fuel multi-injection conducted during forced regeneration of a DPF (12b), control maps for multi-injection are constructed so as to be different for a first gas temperature raising control, which raises a catalyst temperature index temperature (Tg2, Tg1) to a first judgment temperature (Tc1) only by multi-injection, and for a subsequent second exhaust gas temperature raising control, wherein post-injection is conducted in addition to multi-injection to raise a filter temperature index temperature (Tg2) to a second judgment temperature (Tc2). In so doing, exhaust gas flowing into the DPF (12b) can be rapidly raised in temperature when performing forced regeneration of the DPF (12b), thereby shortening the forced regeneration time and improving fuel consumption for forced regeneration.

摘要： When a forced regeneration is restarted after interrupting the forced regeneration, and in at least any one of cases where the collecting quantity area (Rpj) detected by the collecting quantity area detection means (32C) is in another collecting quantity area having a collecting quantity larger than that of the collecting quantity area (Rpi) immediately after interruption, or where the travel distance area (Rmj) detected by the travel distance area detection means (33C) is in another travel distance area, having a travel distance larger than that of the travel distance area (Rmi) immediately after interruption, the forced regeneration is performed from the start, and in other case, the forced regeneration is performed for the remained period of time of the previous forced regeneration, continuing to the previous forced regeneration. Thereby, in the case of an exhaust gas purification system (1), provided with a DPF device (13), when the forced regeneration for the DPF device (13) is restarted after interruption, it is possible to sufficiently burn and remove the PM accumulated in the DPF (13b) and moreover, efficiently regenerate the DPF (13b).

摘要： A method and system providing a vehicle condition detection means (38C) for detecting the stopped and traveling state of a vehicle, and when the vehicle condition detection means (38C) detects that the vehicle has stopped during operation of an exhaust gas temperature raising means (351C), closing an exhaust gas throttling valve (16) in addition to continuing the operation of the exhaust gas temperature raising means (351C), and subsequently, when the vehicle's traveling state is detected, opening the exhaust gas throttling valve (16) and continuing the operation of the exhaust gas temperature raising means (351C). Accordingly, in terms of the regeneration of a continuous regeneration-type DPF device (13) capable of significantly reducing the frequency with which the driver is urged to stop the vehicle and perform forced regeneration, the exhaust gas can be efficiently maintained at a high temperature, and reliable burning of PM is possible even for driving patterns featuring frequent waiting at traffic signals in urban areas, even upon transition to the stationary idling condition during automatic traveling regeneration.

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： In regeneration control in a manual regeneration mode, when a first exhaust gas temperature of an exhaust gas flowing into an oxidation catalyst device is higher than a predetermined determining temperature and an exhaust gas temperature flowing into a DPF device is higher than a predetermined determining temperature and when an intake temperature becomes higher than a predetermined third determining temperature, second exhaust gas temperature control carrying out post injection in addition to multi injection is stopped and switched to third exhaust gas temperature rise control carrying out the post injection in addition to normal injection. Thus, temperature rise of an engine cooling water can be restricted without stopping an air conditioner, and possible overheating of the engine can be prevented.

On the other hand, when the catalyst temperature index temperature (Tg2) is the predetermined first determination temperature (Tc1) or above, the engine speed of idling is brought to a predetermined second target engine speed (Nei2), which is lower than the predetermined first target engine speed (Nei1) and is higher than the engine speed of idling (Nei0) in ordinary operation, and, further, post injection is carried out, followed by raising of the temperature of an exhaust gas flown into a DPF apparatus (12b) to a predetermined second determination temperature (Tc2). According to the above constitution, in the regeneration control of the DPF apparatus (12b) in an internal combustion engine (10), the regeneration can be forcibly carried out with high efficiency while enhancing the temperature rise efficiency of the exhaust gas, and, at the same time, excessive rise in the exhaust temperature, a deterioration in fuel consumption, and the occurrence of noise are suppressed.

摘要： An exhaust emission control system including a continuous regenerating diesel particulate filter (“DPF”) and a DPF controller, wherein a forced regenerator is operated by a driver's request, when it is judged that a traveling distance, after starting particulate matter collection, detected by a traveling distance detector has reached a predetermined judging traveling distance, even when the DPF controller detects that a collection amount detected by a collection amount detector is smaller than a prescribed judging collection amount. Accordingly, in a continuous regenerating DPF capable of manual regenerating, the number of warnings, such as a blinking regeneration button prompting a manual regeneration, is reduced to relieve a driver of annoyance or inconvenience.
