In general terms, a catalytic converter is a very important part of the automobile's exhaust system, which is responsible for reducing the toxicity level of the discharges that come out from the engine. It takes in the harmful emissions from the car engine, and turns the emissions into less harmful substances or water vapor. Such converters are not installed only in automobiles, but are also incorporated in generators, forklifts, huge complex mining set ups, and other machines which make use of engines.
