An exhaust gas purification system (1) comprising a continuous regeneration-type DPF (13) and a DPF control means (30C) is composed to perform an exhaust gas temperature raising control by multi-injection in the case where the collecting quantity (”Pm) exceeds a predetermined first temperature rising judgment collecting quantity (”P01) lower than a predetermined collecting quantity (”P1) and, thereafter, to stop the exhaust gas temperature raising control by multi-injection in the case where the collecting quantity (”Pm) becomes lower than a predetermined second temperature rising judgment collecting quantity (”P02) lower than the predetermined first temperature rising judgment collecting quantity (”P01). Thereby, frequency of the manual regeneration switch operation can be reduced remarkably, and the operability for a driver can be improved, in the exhaust gas purification system (1) prompting the driver to stop the vehicle and perform the forced regeneration by the manual regeneration switch, in the case of detecting that the detected collecting quantity (”Pm) is higher than the predetermined judgment collecting quantity (”P1), concerning the regeneration of the continuous regeneration-type diesel particulate filter device (13) . |
