    摘要: An internal combustion engine exhaust gas purifying system (10) having a continuous regenerating diesel particulate filter system (3) on the exhaust passage (2) of an internal combustion engine (1) is constituted by including collected-quantity estimation means (5A) for estimating the quantity of collected particulate matter in a filter (3b) of the filter system for collecting the particulate matter and maximum-fuel-injection-quantity restricting means (5C) for restricting the maximum fuel injection quantity of the internal combustion engine (1) when the quantity of collected particulate matter estimated by the collected-quantity estimation means (51A) is equal to or more than a predetermined judgment value.Thereby, when the quantity of deposited particulate matter exceeds a predetermined value in the continuous regenerating DPF system (3), it is possible to prevent the continuous regenerating DPF system (1) from deteriorating by restricting the maximum fuel injection quantity of the internal combustion engine (1) and avoiding a great increase of an exhaust gas quantity.

    摘要: In an exhaust gas purifying system wherein an NOx occlusion reduction type catalyst (30) including a catalytic metal and an NOx occluding substance is installed in an exhaust passage (3) of an engine (10), a restore processing against the sulfur poisoning of the NOx occlusion reduction type catalyst (30) is executed, by performing a lax rich control for controlling the air/fuel ratio of the exhaust gas to the theoretical air/fuel ratio or slightly lower than the theoretical air/fuel ratio, when the NOx occlusion reduction type catalyst (30) is heated equal or superior to the sulfur purge temperature.NOx is purified up effectively, by excluding effects of the sulfur poisoning, suppressing the deterioration of fuel-efficiency, by the control method for exhaust gas purifying system.

    摘要: An exhaust gas control system (1) comprised with a continuous regeneration-type DPF (13), an exhaust throttle valve (16) and a DPF control means (30C), wherein the regeneration control is suspended, the multi injection control is performed, and the exhaust throttle valve is closed, when detecting a-stop condition of the vehicle during the regeneration control of the continuous regeneration-type diesel particulate filter device (13) by the regeneration means. Thereby, concerning the regeneration of the continuous regeneration-type DPF device (13), the DPF can be regenerated securely by burning PM efficiently even in a traveling pattern of frequent waiting for the traffic lights to change in urban areas.
