Catalyzed Diesel Particulate Filter (cDPF)

Catalyzed Diesel Particulate Filters (cDPFs) reduce particulate matter, oxidize hydrocarbons, and carbon monoxide in the exhaust to carbon dioxide and water, and form NO2 from NO oxidation to support the functionality of a downstream SCR catalyst.


2 CO + O2 → 2 CO2

CxHy + (x+y/4) O2 → x CO2 + (y/2) H2O

2 NO + O2 → 2 NO2
