Every vehicle, including GMC, uses internal combustion engines to make it move. However, during the process of combustion, the engine emits gasses through the exhaust. Gasses like Nitrogen gas (N2), carbon dioxide (CO2), and water vapor (H2O) that are proved to be harmful to people and contribute to the global warming are truly major threats. As a response, governments create clean-air laws. And to keep to these laws, car manufacturers resulted to refine their car engine and fuel system. One of the results of this refinement is the invention of a device called catalytic converters.
Catalytic converters major purpose is to minimize the release or to convert harmful gasses into cleaner air before they join the air. They are located under vehicle in the middle of the exhaust system. Modern vehicles are equipped with three-way catalytic converters. The term "three-way" refers to the three regulated emissions that help to reduce carbon monoxide, VOCs and Nitrogen Oxide molecules. The reduction catalyst and the oxidation catalyst are the types of catalyst used by the converter. Both consist of a ceramic structure coated with a metal catalyst, usually platinum, rhodium and/or palladium. There are two types of structures used in catalytic converter: the honeycomb and ceramic beds. However, the Honeycomb structure is used in most vehicles.
For GMC vehicles, the catalytic converter provides cleaner air emission. Each GMC vehicle whether a Yukon, Envoy, Savana, Safari, Sierra, Canyon or any other GMC model uses catalytic converter to contribute for cleaner air.
