    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.

    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 emission control system [1] comprising a continuous regenerating DPF [13] and a DPF controlling means [30C], wherein control is so performed as to accept the operation of a forced regenerating means [34C] at an operation request by a driver when it is judged a traveling distance [ΔMc] after starting collection detected by a traveling distance detecting means [33C] has reached a specified judging traveling distance [ΔM1] even when the DPF controlling means [30C] detects a collection amount [ΔPm] detected by a collection amount detecting means [32C] is smaller than a specified judging collection amount [ΔP1]. Accordingly, in a continuous regenerating DPF [13] capable of manual regenerating, the number of warning such as a blinking regeneration button prompting a manual regeneration is reduced to relieve a driver of trouble.

    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： An exhaust gas purification system includes the DPF to purify particulate matters in the exhaust gas of a diesel engine, comprising a regeneration control device to judge a condition of an engine operation to be an idle operation or not at the time of starting the control operation for regenerating the diesel particulate filter and during the regeneration control operation, when the engine operation is judged to be an idle operation, an idle engine speed is controlled and raised to the predetermined engine speed. Since the system includes such structure, in an operation of the DPF regenerate control, an adequate exhaust gas flow rate can be kept even in an idle operation and a raise of the DPF temperature due to a reduction of the exhaust gas flow rate can be avoided so as to prevent a damage of the DPF from melting and a deterioration of the catalyst.
