Aftertreatment DPF Regeneration and PT O Operation

For aftertreatment diesel particulate filter (DPF) regeneration occur , enough heat must generated the diesel oxidation catalyst Heat generated increasing engine speed (RPM) around RPM vehicles with a catalyzed aftertratment For vehicles that operate a power takeof f and have a DPF , the O must have a maximum rated speed above the minimum RPM listed the tables below that aftertreatment diesel particulate filter (DPF) regeneration (whether automatic manual) can occur when

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

Note : Beginning with 198958 and newer software, the only requirement for aftertreatment diesel particulate filter (DPF) regeneration vehicles equipped with MP7 with non - catalyzed DPF and O less than 650 RPM. Altitude and temperature are longer factors for aftertreatment diesel particulate filter (DPF) regeneration and O operation.

Aftertreatment DPF Regeneration and O

Engaged

aftertreatment diesel particulate filter (DPF) manual stationary regenerations with the power takeof f (PT engaged are required, the vehicle must configured follows:

• Set parameter Enable Manual Regen During O (JAC) es” “On” using VCADS. This parameter can found the “Misc. V ehicle section Parameter connection Central Systems required set parameter the vehicle not configured listed above, manual stationary aftertreatment diesel particulate filter (DPF) regeneration with the O engaged will not occur . When aftertreatment diesel particulate filter (DPF) regeneration does not take the DPF will become soot - resulting engine derate and eventual engine

• Initiate Manual Stationary Regeneration using the DPF smart switch.

• Ensur e the electr onic hand thr ottle (engine speed contr ol) active. The engine speed (RPM) must set greater than the minimum speeds listed “ Aftertreatment DPF Regeneration and O Operation ” , page .
