The function and purpose of Catalytic Converter.

Reducing harmful hydrocarbons and noxious gases that come from your car or truck depends on how well you maintain your engine and exhaust parts. Your Hummer H3 catalytic converter has been installed thanks to a federal mandate that is decades old. There are a host of precious metals, mostly platinum, in the catalytic converter that change the harmful emissions of your Hummer H3 from carbon monoxide and hydrocarbons to carbon dioxide and 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.
