Automotive glossary: What is a Catalytic Converter or Exhaust Gas Catalytic Converter?

Definition of Catalytic Converter: With the combustion in an engine, toxic waste products accrue inevitably, like the highly harmful carbon monoxide. So in modern cars, in the exhaust pipe, there is a kind of postprocessing, that converts the carbon monoxide to the innoxious carbon dioxide by a artificially accelerated chemical process. According to the chemical designation of these accelerating substances, the whole component is called "catalytic converter". For a better control of the conversion process, the exhaust systems of modern engines are equipped with one or more measurement devices, see lambda probe.
