Regeneration (continued)
Types of regeneration that are performed manually (while the machine is stationary)
Type
Parked
Recovery
Yanmar Diesel Engine: General Information
Conditions
Occurs when exhaust back pressure in
the DPF increases due to continued soot
buildup. May be caused by prolonged
operation at low engine speed, low engine
load, or the use of incorrect fuel or engine
oil.
May occur if the InfoCenter is set to inhibit
regen (preventing a Reset Regeneration)
and machine operation is continued.
Can be initiated when prompted by the
engine ECU or after a minimum of 50
hours of engine operation.
For software 122−0310J and up: if
a parked regeneration is ignored, the
machine mow function (PTO) will be
disabled approximately 2 hours after the
first notification.
Occurs when exhaust back pressure in
the DPF increases due to soot buildup
reaching a critical level.
Can only be initiated when prompted by
the engine ECU.
For software 122−0310J and up: the
machine mow function (PTO) will be
disabled at first notification.
Description
Manually initiate a parked regeneration as soon as
possible. A parked regeneration requires 30 to 60
minutes and should not be started with less than 1/4
tank of fuel. The machine must remain stationary
(cannot be operated) during the entire parked
regeneration process.
The engine ECU adjusts the exhaust intake throttle
to raise the exhaust temperature.
For all software revisions: the InfoCenter
displays advisory #188 and/or the stationary
regeneration icon .
Manually initiate a recovery regeneration as soon
as possible. A recovery regeneration will take
approximately 3 hours and should not be started with
less than 1/2 tank of fuel. The machine must remain
stationary (cannot be operated) during the entire
recovery regeneration process.
Use the InfoCenter About screen to verify the
software installed on the machine.
•
Machines with software 122−0310A thru H:
Recovery regeneration must be initiated by an
Authorized Toro Distributor service technician
using Yanmar SMARTASSIST-Direct.
•
Machines with software 122−0310J and up:
Recovery regeneration can be initiated from the
machine InfoCenter.
For software 122−0310A thru H only: the
InfoCenter displays the recovery regeneration icon.
For software 122−0310J and up: the
InfoCenter displays advisory #190 and/or the
stationary regeneration icon.
Note: Verify the model and serial number of the
engine installed in the machine. 4TNV98CTNTRL
engines below serial number 16420 cannot run a
recovery regeneration without first reprogramming the
engine ECU. Contact an Authorized Toro Distributor
for assistance.
