diesel particulate filter (DPF)
- Located in the exhaust system after the diesel oxidation catalyst
- “Scrubs” the particulates in the exhaust gases by trapping them after they have left the combustion chamber
- Periodically cleans itself through a process known as “regeneration” which is a process similar to a small incinerator that burns off the trapped particles
- Passive generation burns off soot naturally when exhaust temperatures are high enough
- Active regeneration (forced burn-off) occurs as needed depending on operational use.
