摘要:
In an exhaust gas purification system (1) provided with a continuous regeneration type DPF device (13) and DPF control means (30C), when a collecting quantity (ΔPm) of PM exceeds the predetermined judgment collecting quantity (ΔPm0), a number-of-regeneration-times coefficient (Rc) serving as an index of the number of regeneration times to a travel distance is compared with a predetermined judgment coefficient value (R0). When the number-of-regeneration-times coefficient (Rc) is smaller than the predetermined judgment coefficient value (R0), automatic traveling regeneration is performed and when the number-of-regeneration-times coefficient (Rc) is equal to or more than the predetermined judgment coefficient value (R0), manual regeneration is performed. Thereby, in the case of regeneration of the continuous regeneration type DPF device (13) of the exhaust gas purification system (1), it is possible to greatly decrease the frequency of manual regeneration in which a driver stops a vehicle to perform forced regeneration by a manual regeneration switch and improve the operability for the driver. Moreover, it is possible to solve the oil dilution problem due to a lot of unburned oil injected for DPF regeneration.

If this condition is not met, manual regeneration is performed.
摘要:
A printing machine comprising a conveyance path for conveying printing paper, and a position sensor for detecting the end of the printing paper passing through the conveyance path. Printing is carried out at a prescribed position on the printing paper, in accordance with this position sensor. The position sensor is located movably in a transverse direction to the conveyance path. It can be withdrawn to a position where it poses no obstacle when setting printing paper in the conveyance path.
