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.
