  Oxidation catalytic converter task Reducing the pollutant components of carbon monoxide (CO), hydrocarbon (HC), oxides of nitrogen (NOX ) and particulates
(PM = particulate mass).
 
  Oxidation catalytic converter design   GF49.10-P-3000-01GB 
  Oxidation catalytic converter function Oxidation converts CO into CO 2 and HC into CO2 and H2 O. This reduces the emitting particulate mass (PM) because the HC adhering to the carbon (soot) is reduced during post-oxidation. In addition, a part of the oxides of nitrogen (NO X ) is converted into nitrogen (N2 ) by reduction.
