The catalytic converter is a device that reduces harmful exhaust emissions by chemically converting poisonous gases into less harmful ones through an oxidizing reaction. It consists of a honeycomb structure made of ceramic material coated with precious metals like palladium, platinum, and rhodium. The chemical reaction generates heat, promoting the reaction. However, the ceramic structure is fragile and can be damaged by rough treatment or driving through deep water. It is important to avoid using leaded gasoline, maintain the ignition and fuel systems, and address any engine misfires promptly. Push-starting or tow-starting the car should be avoided, as well as switching off the ignition at high engine speeds. Fuel and engine oil additives should not be used, and if the engine burns oil excessively or leaves a trail of blue smoke, the car should not be continued to be used. Parking the car in dry undergrowth or over long grass after a long run should be avoided. The catalytic converter operates at high temperatures, and driving through deep water can cause the ceramic honeycomb to fracture. It is important to handle the converter with care during servicing and not strike it with tools. A sulphurous smell from the exhaust may be noticed, which is more related to the sulfur content of the fuel than the converter itself. A substantial loss of power may indicate a blocked converter, which may require replacement. A well-maintained and well-driven car can expect the catalytic converter to last between 50,000 and 100,000 miles.
