Diesel Particulate Filters

The Diesel Particulate Filter (DPF) is designed to reduce particulate matter from coming out of the exhaust stream. The internal Cordierite or Silicon Carbide substrate is a wall-flow filter containing alternating blocked channels that forces exhaust gas through its porous walls, therefore capturing the particulate matter. Your equipment’s on-board regeneration system heats the DPF’s internal substrate to breakdown or oxidize the captured Particulate Matter. The by-product of each regeneration cycle is ash and other inert debris that will remain in the filter. Be aware that a DPF will mask all previous inherent or diagnostic signs. Historically poor engine performance could be noted by the exhaust i.e. black, blue, or white smoke. With a DPF system installed, there is no longer any visible smoke. Some filters may need to be cleaned in shorter intervals depending upon vehicle maintenance and duty cycle.
