摘要： An exhaust gas purification system has an exhaust gas purification device (12) for purifying components in exhaust gas from an internal combustion engine (10) such as a diesel engine. In order to recover the purification ability of the exhaust gas purification device (12), and in order to prevent oil dilution occurring when post injection is conducted as part of an in-cylinder fuel injection control during an exhaust gas temperature raising control that raises the temperature of exhaust gas, the system performs the following. In a regenerative control for recovering purification ability of the exhaust gas purification device (12), injection quantities (Qp) of post injections are calculated based on previously set map data (Mp), accumulated to calculate a post injection accumulated injection amount (ΣQp), and, when the accumulated injection amount (ΣQp) exceeds a predetermined determination value (Cp), the post injection is stopped to cease the regenerative control.

摘要： At regeneration control while a vehicle mounting an internal combustion engine (10) is parked, both an exhaust throttle valve (13) and an exhaust brake valve (18) are used and if a catalyst temperature index temperature (Tg2) is lower than a predetermined first determining temperature (Tc1), first exhaust gas temperature rise control is conducted that the exhaust brake valve (18) is set to a fully closed side and multiple injection is carried out in in-cylinder fuel injection control, while if a catalyst temperature index temperature (Tg2) is equal to the predetermined first determining temperature (Tc1) or above, second exhaust gas temperature rise control is conducted that the exhaust brake valve (18) is set to an open side, the exhaust throttle valve (13) is set to the fully closed side, and post injection is carried out in the in-cylinder fuel injection control. By this arrangement, while temperature rise efficiency of an exhaust gas flowing into a DPF (12) is enhanced, forced regeneration is carried out efficiently in a short time with avoiding overheat or abnormal combustion at the regeneration control of the DPF (12) while the vehicle is parked.

摘要： In an exhaust gas purification system (1) for conducting control of raising temperature of a DPF (12b) by supplying an unburned fuel to an upstream side of an oxidation catalyst to oxidize it, a minimum value (Qumin) of a first upper limit value (Qu1) acquired by subtracting a fuel injection amount (Qe) for in-cylinder combustion from a first combustible fuel amount (Qa1) limited by an air/fuel ratio, a second upper limit value (Qu2) acquired by subtracting the fuel injection amount (Qe) for in-cylinder combustion from a second combustible fuel amount (Qa2) limited by an atmospheric pressure, and a third upper limit value (Qu3), which is a third combustible fuel amount (Qa3) which can be oxidized by the oxidation catalyst limited by a catalyst temperature index temperature (Tg1, Tg2) and an engine speed (Ne) is set as an upper limit value (Qu) for the unburned fuel supply amount (Qp). 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： 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.

摘要翻译： 基于柴油机微粒过滤器两端的压差与过滤器两端的规定压差阈值进行比较，判断用于净化废气中的颗粒物质的柴油微粒过滤器的强制再生开始时刻。 通过将基准压差阈值乘以根据先前强制再生之后的车辆行驶里程而逐步或连续变化的系数来设定预定差压阈值。 因此，可以通过燃烧来除去颗粒物质，同时过滤器中不均匀地累积的颗粒物质的量仍然很小，并且过滤器由于强制再生过程中的过度积聚而导致过高的温度上升，并且由于过滤器的熔化损失 可以防止过度的温度上升。

摘要： In regeneration control, when the catalyst temperature index temperature (Tg2) using the temperature of the oxidation catalyst (12a) as an index is below a predetermined first determination temperature (Tc1), the engine speed of idling is brought to a predetermined first target engine speed (Nei1) which is higher than the engine speed of idling (Nei0) in the ordinary operation, and, further, multi-injection is carried out. 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.

摘要： An exhaust gas purification system including an exhaust gas purification device having an oxidation catalyst device including an oxidation catalyst and a diesel particulate filter (“DPF”) arranged in order from an upstream side, or a DPF carrying an oxidation catalyst in an exhaust passage of an internal combustion engine. At regeneration of the DPF, when a catalyst temperature index temperature (Tg2), indicating a temperature of the oxidation catalyst, becomes equal to a predetermined determining temperature (Tc1) or above, a temperature of the DPF is raised by supplying an unburned fuel to the upstream side of the oxidation catalyst to thereby oxidize the unburned fuel by the oxidation catalyst. The predetermined determining temperature (Tc1) is changed according to an engine speed Ne of the internal combustion engine. By so oxidizing the unburned fuel supplied into an exhaust gas by the oxidation catalyst, outflow of white smoke is prevented regardless of an operation state of the internal combustion engine.

摘要： In case of emergency regeneration, i.e. any one of forced regeneration after a judgment is made that purification is insufficient in purification judgment after ending forced regeneration, forced regeneration after time has expired before completing of forced regeneration, or forced regeneration when the pressure difference across a DPF exceeds a predetermined first judging pressure difference under a state where traveling distance of a vehicle is shorter than a predetermined distance for judgment an alarm for urging manual regeneration is issued, and wherein when manual regeneration is designated thereafter manual regeneration is performed and when predetermined conditions are satisfied without the reception of a designation of manual regeneration, automatic regeneration is performed. In forced regeneration of the DPF for purifying PM in exhaust gas, forced regeneration is performed surely even if manual regeneration is not selected at the time of emergency regeneration, and convenience is enhanced by reducing burden on a driver.
