What is the purpose and importance of the catalytic converter on Ford Focus?

The catalytic converter reduces harmful exhaust emissions by transforming poisonous gases into safer ones using a fragile ceramic honeycomb structure coated with metals like palladium, platinum, and rhodium. This process generates heat. To prevent damage, avoid rough driving, leaded gasoline, and any engine misfires. Don't push-start or tow-start the car, switch off the ignition at high speeds, use fuel and engine oil additives, or drive if the engine burns oil excessively. After a long run, avoid parking on dry undergrowth or long grass. Handle the converter carefully during servicing. Sulphurous exhaust smell is generally due to fuel's sulfur content, not the converter. A significant power loss may signal a blocked converter, which may need replacement. A properly maintained car can have a catalytic converter lasting 50,000 to 100,000 miles.
