A catalytic converter is an essential component of a vehicle’s exhaust system, designed to reduce harmful emissions. It works by converting toxic gases and pollutants from the engine into less harmful substances before they are released into the atmosphere. Inside the converter, a ceramic or metallic honeycomb structure is coated with precious metals like platinum, palladium, and rhodium. These metals act as catalysts to trigger chemical reactions that transform carbon monoxide, nitrogen oxides, and hydrocarbons into carbon dioxide, nitrogen, and water vapor. Catalytic converters are a key part of meeting environmental regulations and play a crucial role in reducing air pollution.
