Function of the Oxidation Catalyst
The pollutant gases produced by combustion pass through the oxidation catalyst (DOC), also called two-way catalyst, because it treats two types of gases: Hydrocarbons (HC) and Carbon Monoxide (CO). Inside the catalyst, there is a ceramic or metallic material containing precious metals, essentially platinum, which react with the exhaust gases by means of a chemical process. The process carried out inside the catalytic converter allows hydrocarbon (HC) and carbon monoxide (CO) emissions to be converted into carbon dioxide CO2 and water H2O.
