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.

Figure 20 — Minimum Engine Speeds for MP10 with Cat DPF 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.
