a converter that uses a platinum-iridium catalyst to oxidize pollutants and carbon monoxide into carbon dioxide and water; an antipollution device on an automotive exhaust system
(Otomotiv) Part of the exhaust system, this pollution-control device found on many newer cars it re-burns unburned gas in the exhaust system before it leaves your vehicle as exhaust
A catalytic converter is a device which is fitted to a car's exhaust to reduce the pollution coming from it. A reaction chamber typically containing a finely divided platinum-iridium catalyst into which exhaust gases from an automotive engine are passed together with excess air so that carbon monoxide and hydrocarbon pollutants are oxidized to carbon dioxide and water. a piece of equipment fitted to a car's exhaust system that reduces the amount of poisonous gases the engine sends out. In automobiles, a component of emission control systems used to reduce the discharge of noxious gases from the internal-combustion engine. The catalytic converter consists of an insulated chamber containing pellets of catalyst through which the exhaust gases are passed. The exhaust's hydrocarbons and carbon monoxide are converted to water vapour and carbon dioxide
