Catalytic Converter Information

What is a Catalytic Converter?

Since 1975, all vehicles produced in the United States must have a catalytic converter as part of the exhaust system. The catalytic converter is an emissions-control device that contains precious metals that act as catalysts. The catalyst (in the form of platinum and palladium) is coated onto a ceramic honeycomb or ceramic beads that are housed in a muffler-like package attached to the exhaust pipe. When hot exhaust enters the converter, a chemical reaction occurs that renders toxic gases, such as carbon monoxide and hydrocarbons, into less harmful emissions. The catalyst helps to convert carbon monoxide into carbon dioxide. It converts the hydrocarbons into carbon dioxide and water. It also converts the nitrogen oxides back into nitrogen and oxygen.

Catalytic Converter Filtration Process
The Catalytic Converter filters out the exhaust and breaks it down to less harmful emissions.
