About Catalytic Converter
A catalytic converter is a device which controls the emission of exhaust gases generated in an engine's combustion chamber. Catalytic converters are used to minimise emissions and increase the efficiency of the gases emitted from the exhaust system
How Catalytic Converter Works?
A catalytic converter is a tool that uses a catalyst to transform through a chemical method the toxic and poisonous gases that come out of the exhaust system. Catalytic converter is made from platinum and palladium with a honeycomb structure enclosed in a metal shell and attached to the exhaust pipe. Catalytic converters main function is to transform the carbon monoxide into carbon dioxide and water, converting nitrogen oxide (NOx) back into nitrogen and oxygen as well. The primary stage is the reduction catalyst, where platinum and rhodium help to reduce the NOx emissions. The second stage is called the oxidation catalyst, at this stage it removes unburned hydrocarbons and carbon monoxide by burning them over a catalyst for platinum and palladium, and the final stage is the conversion is a control device that can track the exhaust system output.
Where is Catalytic Converter Located?
Catalytic converters, after the exhaust manifold and before the silencer or muffler, are located in the exhaust system.
