    摘要： Even in the case of driving for a long time in the low rotation speed driving condition in which the exhaust flow rate is small and an estimation of the PM accumulated amount due to the pressure difference between the front and the back sides of a filter is difficult, the forced regeneration time can be accurately judged, the deterioration of fuel efficiency that is caused by excessive PM trapping can be avoided, and at the same time, thermal runaway that is generated by the excessive accumulated amount of PM and melting damage of the DPF due to this thermal runaway can be prevented. In the exhaust gas purification system 1 that performs a forced regeneration control by judging a forced regeneration starting time of the DPF 12b from the pressure difference ΔPm between the front and the back sides of the DPF 12b, in the case of detecting that the driving condition of the internal combustion engine 10 is a low rotation speed driving condition, the sustaining time tm of the low rotation speed driving condition is measured, and when the measured sustaining time tm exceeds the predetermined time for judgment tc, the forced regeneration control of the DPF 12b is performed without affecting the pressure difference ΔPm between the front and the back sides of the DPF 12b.

    摘要： When an internal combustion engine is in a low rotation speed driving condition, a duration of the low rotation speed driving condition is measured, and when this duration exceeds a predetermined time, the forced regeneration control is performed. Thus, even when an exhaust flow rate is small and an estimation of a particulate matter accumulated amount due to a pressure difference between front and back sides of a filter is difficult, a forced regeneration time can be accurately judged, the deterioration of fuel efficiency that is caused by excessive trapped particulate matter can be avoided, and thermal runaway that is caused by the excessive particulate matter, and the melting damage of the diesel particulate filter due to this thermal runaway, can be prevented.

    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： 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.
