What the Catalytic Converter Is and How It Works
The catalytic converter is part of your vehicle’s exhaust system. Because the engine creates exhaust gases during combustion, those gases travel through the catalytic converter before leaving the vehicle. So, the converter helps reduce harmful emissions.
Then, exhaust passes through special materials inside the converter. Next, those materials create chemical reactions that change harmful gases into cleaner emissions. Also, this process happens continuously while driving. Because cleaner exhaust supports efficient operation, the vehicle performs better.
