The function and purpose of Catalytic Converter.

Reducing harmful hydrocarbons and noxious gases that come from your car or truck depends on the quality and performance of the parts you use. Your Audi A4 catalytic converter is likely the single most effective pollution control device on production vehicles today. There are a host of precious metals, mostly platinum, in the catalytic converter that turn the carbon monoxide and hydrocarbons that your Audi A4 produces into harmless molecules of carbon dioxide, oxygen, and some water. Thanks to this chemical reaction, automakers could now curb their contribution to air pollution, which is why every vehicle made today has a catalytic converter.
