    摘要: An exhaust emission purification system having a controller performing exhaust temperature rise control including 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 including 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. The multistage delay injection control is forbidden when an idle operation state of an internal combustion engine occurs for a predetermined judgment time and a power take-off device is operating. A control method for exhaust emission purification is also provided sustaining a diesel particulate filter for purifying particulate matter in exhaust gas by executing forced regeneration while avoiding variation in engine speed, even if the power take-off device is operating during an extended idling operation.

    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: In forced regeneration control of an exhaust gas purification device a number of data for injection control, such as a number of meshes of a data map and a 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 this forced regeneration control, when an operation state of an internal combustion engine is a high-load operation state, the normal injection control by stopping the multi injection is carried out and, according to a rotation speed and a load of the internal combustion engine, a region for control is divided into a multi-injection control region, a transition region, and a normal injection control region. In the transition region, data for injection control obtained by interpolation of data for injection control on the multi-injection control region side and data for injection control on the normal injection control region side is used.

    摘要: When an engine cooling water temperature (Tw) detected by a cooling water temperature detection means (37C) exceeds a predetermined judgment water temperatures (Tw1 and Tw2) during the forced regeneration control of a filter using exhaust gas temperature raising means (351C), the actuation of the exhaust gas temperature raising means (351C) is interrupted.Thereby, in the case of the exhaust gas purification system having a DPF apparatus (13), it is possible to prevent a water temperature meter in a driver seat from abnormally rising during the forced regeneration of a DPF (13b) and to prevent a driver from taking the abnormal rise of the water temperature meter for an engine trouble.
