How Catalytic Converters Work
How does a catalytic converter work?
A catalytic converter works by using a catalyst to create a chemical reaction that converts harmful gases produced by an engine into less harmful emissions. The converter is part of the vehicle’s exhaust system and is located between the engine and the muffler. It contains a honeycomb structure coated with catalyst materials, typically platinum, palladium, and rhodium, which are metals that facilitate reactions. As exhaust gases like carbon monoxide, nitrogen oxides, and hydrocarbons pass through the converter, they react with the catalysts. This reaction breaks down the pollutants into less harmful substances such as carbon dioxide, nitrogen, and water vapor, thereby reducing environmental impact.
