The function and purpose of Catalytic Converter.

Achieving maximum fuel efficiency while reducing emissions on your car or truck depends on how well you maintain your engine and exhaust parts. Your GMC Sierra 1500 HD catalytic converter has been installed thanks to a federal mandate that is decades old. Inside every catalytic converter are cells made from platinum and/or rhodium arranged in a honeycomb pattern that turn the carbon monoxide and hydrocarbons that your GMC Sierra 1500 HD 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.
