[3] DPF REGENERATION SYSTEM
(1) Regeneration Mode (Inhibit Version)
This system has "Auto Regeneration Mode" in which the DPF can regenerate automatically while working, "Inhibit
Mode" in which the auto regeneration is inhibited and "Parked Regeneration Mode" in which the DPF regenerates
while the tractor is parked.
Auto Regeneration Mode
Press the auto regeneration switch, and the Auto Mode is activated. The tractor has been set to Inhibit Mode by
default. When the main key switch is turned ON, the tractor will be in the Inhibit Mode. By pressing the auto
regeneration switch, the mode can be switched to the Auto Regeneration Mode.
When an amount of PM more than specified has built up in the DPF muffler, the DPF is automatically regenerated
under the specified condition through the heat generated by the chemical reaction of between DOC (Diesel Oxidation
Catalyst) and post injection fuel whether the tractor is in motion or parked.
For jobs not affected by hot gases emitted out of the DPF muffler during regeneration, the Auto Regeneration
Mode is advisable.
Inhibit Mode
The tractor has been set to Inhibit Mode by default.
Even if an amount of PM more than specified has built up in the DPF muffler, the DPF does not regenerate. When
the regeneration is needed, the indicator starts flashing to notify the operator to active Auto Regeneration Mode or
conduct a Parked Regeneration Mode, at once in a safe area.
For jobs that are done in poorly ventilated area or in area that may affect plants and animals because of hot gases
that will be emitted, the Inhibit Mode is recommended.
Parked Regeneration Mode
When an amount of PM more than specified has built up in the DPF, the indicator starts flashing to notify the
operator that Regeneration is required and it is possible to do the parked regeneration under the specified condition.
Therefore, park the tractor in a safe place and do the regeneration. In the Parked Regeneration Mode, the DPF
regeneration is conducted under the condition controlled by the ECU in which the accumulated PM is burned off
slowly and steadily for the safety.
