Regeneration Terms and Definitions
DPF: Diesel Particulate Filter
Regen: Typically refers to the reset or stationary regeneration mode of the DPF,
but could also refer to other regeneration modes, such as an assist or passive
regeneration.
PM: Particulate matter in the DPF
Hours: Refers to the engine run-time hours
E-ECU: Refers to the Engine-ECU Control Unit
DTC: Diagnostic Trouble Codes
EGT: Exhaust Gas Temperature
Passive regeneration and assist regeneration: These automatic DPF regen
modes occur without any operator input and without affecting machine opera-
tion.
Reset regeneration: This DPF regen mode intentionally increases exhaust gas
temps to remove PM. Review all precautions regarding high exhaust temps. The
operator can continue to operate all skid-steer loader functions. Reset regenera-
tion is initiated by the E-ECU, but the operator has the option to delay this func-
tion. A reset-regeneration is a 100 hour recurring event unless other factors, such
as engine load and effective PM levels determine otherwise.
Note: The operator can improve the effectiveness of the reset regen by oper-
ating the skid-steer loader at a middle to high throttle position during the reset
regen.
Stationary Regeneration: This DPF regen mode includes engine speed control
for a more effective and complete DPF regen. When the DPF regen-required
lamp illuminates, the operator should move the skid-steer loader to a safe place
without flammable material nearby before operating the stationary regen. For
operation and other details, refer to the flow chart and stationary regen operating
procedures.
Backup Mode: In the backup mode, the engine has reduced revolutions per
minute (RPM) and power. A number of DTC’s are to be expected. Refer to the
DTC listing (page 81) for a complete summary and troubleshooting techniques.
To cancel the backup mode, the service tool (Smart Assist) is required. Contact
your dealer for full details.
Ash Cleaning Mode: The ash cleaning mode details are under development.
Contact your dealer for information.
