DOC (Diesel Oxidation Catalyst)
Since 1991, diesel oxidation catalysts have been used in passenger cars in Europe, and for a certain time with commercial vehicles in the USA. They reduce the amount of carbon monoxide (CO) and hydrocarbons (HC) in the exhaust gas by oxidizing them to carbon dioxide and water at high temperature (>100°C).
2 CO + O2 → 2 CO2
CxHy + (x+y/4) O2 → x CO2 + (y/2) H2O
Diesel Oxidation Catalysts (DOC) are catalytic converters designed specifically for diesel engines and equipment to reduce carbon monoxide (CO), hydrocarbons (HC), and soluble organic fractions (SOF). It can be used in combination with CDPF or SCR/SCRF due to its ability of oxidizing NO to NO2 which improves the passive regeneration and fast-SCR reaction. Injected fuel can also be fast catalytically ignited to initiate the active regeneration of DPFs.
