A catalytic converter is that pot/box under your car in the exhaust system. Its job is to *clean the dirty smoke from your engine before it comes out.*
Main Function:
1. *Converts harmful gases to harmless ones:*
- Carbon Monoxide (CO) - poisonous -> converts to Carbon Dioxide (CO2)
- Hydrocarbon (unburnt fuel) -> converts to CO2 + Water
- Nitrogen Oxides (NOx - causes smog) -> converts to Nitrogen + Oxygen
