Richer catalyst technologies for emissions control-Control Technologies for Particulate Matter(CSF/CDPF)

Particulate filters are generally used with diesel engines to remove diesel particulate matter (PM), but in principle can be used with other types of engine/fuel combinations, although these produce less particulate matter. Based on engine technology and application specificities, different filter technologies may be used to reduce particles emissions.

Diesel Particulate Filters (DPFs) have been applied to production vehicles since 2000 and are now standard equipment on most new diesel cars in Europe. Some buses and trucks meeting the Euro IV, V and EEV (Enhanced Environmentally-friendly Vehicle) emissions standards are equipped with DPFs and most Euro VI heavy-duty vehicles are expected to be equipped with them so as to meet the PM mass and particle number emissions requirements. There is, as a result, quite an active field of development in regeneration optimization, substrates materials and catalyst improvements plus developments in related On-Board Diagnostics.
