DIESEL EXHAUST SYSTEM: OXIDATION CATALYST/DIESEL PARTICULATE FILTER SYSTEM (F-SUPER DUTY ONLY) Your vehicle is equipped with a diesel particulate filter (DPF), which is coupled to a diesel oxidation catalyst, that reduces the amount of harmful exhaust emitted from the tailpipe. As soot gathers in the system it begins to restrict the filter. The soot gathered inside the filter needs to be periodically cleaned. The soot can be cleaned in two different ways; passive regeneration and active regeneration. Both methods occur automatically and require no actions from the driver/operator. During either one of these regeneration methods you may notice an increase/change in exhaust noise/tone and increased engine idle speed. 51 2009 Econoline (eco) Supplement, 2nd Printing USA (fus)
