    摘要： In an exhaust gas temperature raising control for recovering purification ability of an exhaust gas purification device of an internal combustion engine, the exhaust gas temperature is efficiently raised to a target level without producing white smoke. In recovery control of the exhaust gas purification device, when the temperature of the exhaust gas flowing into the exhaust gas purification device is lower than a predetermined judgment value, a first exhaust gas temperature raising control that does not include post injection but includes intake air restriction is performed, and when equal to or higher than the predetermined judgment value, a second exhaust gas temperature raising control that includes both the post injection and the intake air restriction is performed to set an intake air restriction amount in the first exhaust gas temperature raising control greater than an intake air restriction amount in the second exhaust gas temperature raising control.

    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： A method (1) of controlling an exhaust gas purification system has a DPF device (12), where a regeneration control means (35C) has a forced regeneration mode and an arbitrary regeneration mode. In the forced regeneration mode, when it is determined by a regeneration time determination means (34C) that it is time to regenerate a filter (12b) and the temperature of exhaust gas is low, the exhaust gas temperature is raised by an exhaust gas temperature raising means (351C) to forcibly regenerate the filter (12b). In the arbitrary regeneration mode, the filter is arbitrary regenerated based on the result of detection by a collection amount detection means (32C). While the temperature of exhaust gas is raised in the arbitrary regeneration mode by the exhaust gas temperature raising means (351C), operation of a compressor (41) of a vehicle air conditioner is stopped. By means of this, the temperature (Tw) of engine (10) coolant is prevented from abnormally rising while the DPF device (12) is forcibly recovered by arbitrary regeneration.

    摘要： In forced regeneration control of an exhaust gas purification device 12, the number of data for injection control such as the number of meshes of a data map and the number of data maps for multi injection control is decreased while occurrence of torque shock, which is a rapid fluctuation of a generated torque, is avoided. In the forced regeneration control of the exhaust gas purification device 12, when an operation state of an internal combustion engine 10 is a high-load operation state, the normal injection control by stopping the multi injection is carried out and according to a rotation speed Ne and a load Q of the internal combustion engine 10, a region for control is divided into a multi-injection control region Rm, a transition region Rt, and a normal injection control region Rn, and in the transition region Rt, data Ft(i) for injection control obtained by interpolation of data Fml(i) for injection control on the multi-injection control region Rm side and data Fnl(i) for injection control on the normal injection control region Rn side is used.

    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： 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).
