Automotive Catalytic Converter

Automotive catalytic converters are devices that are part of the exhaust system of a vehicle. They are designed to reduce harmful emissions from the engine by converting toxic gases and pollutants into less harmful substances before they are released into the atmosphere.

Catalytic converters contain a catalyst, usually made of platinum, palladium, and rhodium, which facilitates chemical reactions that convert harmful gases such as carbon monoxide, nitrogen oxides, and unburned hydrocarbons into carbon dioxide, nitrogen, and water vapor.

These devices are typically made of a stainless steel housing with a ceramic or metallic substrate coated with the catalyst. They are installed in the exhaust system of a vehicle, usually between the engine and the muffler, and they work by promoting chemical reactions that break down and convert harmful emissions into less harmful compounds.

Automotive catalytic converters are an essential component of modern vehicles, as they help to reduce air pollution and comply with emission regulations. They are commonly used in gasoline-powered vehicles, but they can also be found in some diesel-powered vehicles.

In the supply class Miscellaneous Engine Accessories, Nonaircraft, automotive catalytic converters are categorized as engine accessories that are not specific to aircraft engines. They are part of the broader category of engine accessories, which includes various components and parts that are used to enhance the performance, efficiency, and functionality of an engine.
