Diesel particulate filters

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.
