The Role of Exhaust Systems in Vehicle Emissions Control
The role of exhaust systems in vehicle emissions control is crucial for reducing harmful pollutants released into the atmosphere. Exhaust systems are designed to channel the gases produced during combustion away from the engine and into the environment, but they also play an active role in treating those gases to minimise their impact. Key Components and Functions Catalytic Converter : This is one of the most vital components of an exhaust system. It facilitates chemical reactions that convert harmful gases—such as carbon monoxide (CO), nitrogen oxides (NOx), and sunburned hydrocarbons (HC)—into less harmful substances like carbon dioxide (CO2), nitrogen (N2), and water vapour (H2O). Catalytic converters typically use precious metals like platinum, palladium, and rhodium as catalysts to promote these reactions. Muffler : While primarily designed to reduce noise produced by the engine, mufflers also help control emissions by promoting the proper flow of exhaust gases, which can aid in
