Catalytic Converter

The catalytic converter converts harmful pollutants in the exhaust gas into harmless gases. It is located in the exhaust system and all exhaust gas must flow through it. The catalyst encourages the chemicals to react with each other and as a result the leaving exhaust gas contains less carbon monoxide, hydro carbon and nitrous oxide. A catalytic converter may have two different catalysts. One catalyst treats the hydro-carbon (HC) and carbon monoxide (CO). Other catalyst treats nitrous oxide (NOx). The first catalyst for HC and CO encourages HC to unite with oxygen to become H2O that is water and CO2 that is carbon-di-oxide. This type of converter is an oxidizing converter because it oxidizes the HC and CO.
