Aftertreatment DPF Regeneration and PTO
Operation
For aftertreatment diesel particulate filter (DPF) regeneration to occur, enough heat
must be generated in the diesel oxidation catalyst (DOC). Heat is generated by
increasing engine speed (RPM) to around 1,100 RPM on vehicles with a catalyzed
aftertratment system. For vehicles that operate a power takeoff and have a DPF, the
PTO must have a maximum rated speed above the minimum RPM listed in the tables
below so that aftertreatment diesel particulate filter (DPF) regeneration (whether
automatic or manual) can occur when commanded.

Note: For vehicles equipped with a catalyzed DPF, the PTO must be activated by a
switch that provides both engagement and speed information to the vehicle electronic
control unit (VECU) when the PTO is engaged. The vehicle operator must use engine
speed control to set engine speed when the PTO is in operation.
