Abstract:
1. An exhaust gas purifying system for a diesel engine comprising; a continuous regenerating diesel particulate filter in a passage of an exhaust gas from an engine in a vehicle; and a diesel particulate filter control means having wherein the diesel particulate filter control means performs automatic traveling regeneration, when the detected traveling distance (ΔMc) exceeds a second threshold value (ΔM2) and when the detected collection amount (ΔPm) exceeds the prescribed determining collection amount (ΔP1), accepts the operation of the forced regeneration means, when such operation is manually requested by the driver, if the detected traveling distance (ΔMc) is determined to have reached another first threshold value ΔM1 based on a prescribed determining traveling distance which is an upper limit at which oil dilution occurs when a manual forced generation is performed while a vehicle is stopped, and which is the first threshold value (ΔM1) being smaller than the second threshold value (ΔM2), even when the detected collection amount (ΔPm) is detected as being smaller than the prescribed determining collection amount (ΔP1).
