Particle oxidation catalysts (POC) are devices that can capture and store carbonaceous PM material for a period of time sufficient for its catalytic oxidation, while having open flow-through passages that allow exhaust gases to flow, even if the PM holding capacity is saturated.

Working Principle of DOC+CDPF
Doc: Oxidation of No to No2 and removal of CO and HC.
CDPF: the captured carbon particles react with NO2 at low temperature to produce CO2 emissions.
