  Catalytic converter - Wikipedia, the free encyclopedia
A catalytic converter (colloquially, "cat" or "catcon") is a device used to reduce the toxicity of emissions from an internal combustion engine.
In that case, the converter's two oxidizing reactions (oxidation of CO and hydrocarbons) are favoured, at the expense of the reducing reaction.
Catalytic converters become ineffective in the presence of lead due to catalyst poisoning.

Engineers estimate that during the last 11 years 130 million catalytic converters used in the U.S. have eliminated automotive pollutants that-if unchecked and unabated-could have covered the country with a toxic blanket of carbon monoxide more than 500 feet deep.
Catalytic converters typically consist of a ceramic or metal honeycombed monolith substrate that carries precious metal catalysts.
A catalytic converter is not a stand-alone cure-all for emissions control.

A catalytic converter is a device which chemically converts harmful exhaust gases, produced by the internal combustion engine, into harmless carbon dioxide and water vapor.
The converter was developed to meet stringent emission reduction levels as set forth by the Federal ERA and California Air Resources Board.
This is not the problem of the converter itself, but the result of a problem with the fuel system or ignition that allows unburned fuel to pass through the engine to the converter.
