Diesel Particulate Filter (DPF)
• The last step in the exhaust aftertreatment process
and designed to scrub any remaining soot from
the exhaust
– Soot can be described as the black smoke seen in
diesel exhaust
• Located in the exhaust system, after the SCR
• Periodically cleans itself through a process known as
"regeneration," which is similar to a small incinerator
burning off trapped particulates
– Passive regeneration naturally burns off soot when
exhaust temperatures are high enough
– Active regeneration (forced burn-off) occurs as
needed, depending on operational use
NOTE: For more specific information about
the regeneration process, please refer to the
Maintenance and Specifications section of the
vehicle Diesel Supplement.

Operator Commanded Regeneration
(OCR; 98R)
• Extra-cost feature available only on XL and XLT with
base instrument cluster (requires 6.7L Power Stroke
diesel engine)
• OCR allows customer to actuate a manual Diesel
Particulate Filter (DPF) regeneration with the vehicle
at idle
• OCR is a very specialized option requiring the customer
have full knowledge of proper use and actuation — it's
highly recommended the dealer and the customer
review pages 56–58 of the most recent Super Duty
Diesel Supplement for more information
• OCR is not recommended for general customer use,
includes a $250 MSRP and is intended for unique
applications where the vehicle is rarely, if at all, driven
above 15–20 mph and/or experiences extended
idle periods
– Vocations where the above can occur are oil
refineries, underground mining, line repair and
tree trimming
– Customers within these vocations may find it
beneficial to have the option of a manual DPF
regeneration during a work cycle
