• Functions:
  
  • Hydrocarbon (HC) oxidation: It oxidizes unburned hydrocarbons, reducing their emissions and improving fuel efficiency.
    
  • Particulate matter (PM) reduction: The DOC can also contribute to reducing PM emissions, although its primary function is to address CO and HC.
    
  • Carbon monoxide (CO) Oxidation: The DOC converts CO, a toxic gas produced during incomplete combustion, into carbon dioxide (CO2), a less harmful gas.
    
  • Temperature management: The DOC can help to regulate the temperature of the exhaust gases, which is important for the proper functioning of other emissions control devices like the Diesel Particulate Filter (DPF).
