Exhaust purification system

The present invention provides an exhaust gas purification system. With a continuous regeneration type DPF in (13 is) and a DPF control means (3OC) of the exhaust gas purification system (1), configured as the DPF control means (3OC) performs control such that even when the trapping amount detected by the detection means trapping amount (32C) detected ([Delta] Pm) than a predetermined judgment collecting quantity ([Delta] P1) is smaller case, after the start of the capture by the travel distance detection means for detecting (33C) travel distance (Mc) reached Analyzing the case where the predetermined running distance (AM1), and perhaps by the action of the forced regeneration means requested by the driver is performed (34C) operation. Thus, continuous regeneration can be performed in DPF (13) in the manual regeneration, and the number of warnings urging manual regeneration blinking regeneration button or the like becomes small, reducing the driver's sense of boredom.
