CATALYTIC CONVERTER CHECK

Catalytic Converter

A catalytic converter is an exhaust emission control device that converts toxic gases and pollutants in exhaust gas from internal combustion engines into less toxic pollutants. 1 Catalytic converters are used with internal combustion engines in automobiles.

Catalytic converters contain one or more catalysts, usually platinum, palladium, and rhodium. These metals provide the surface area required for the chemical reactions that convert toxic pollutants into less harmful substances.

The primary pollutants targeted by catalytic converters are:

• Hydrocarbons (HC)
• Carbon monoxide (CO)
• Nitrogen oxides (NOx)

Catalytic converters operate at high temperatures, typically around 800 degrees Fahrenheit (427 degrees Celsius). This high temperature is necessary for the chemical reactions to occur.

Catalytic converters are a vital component of modern automobiles, helping to reduce air pollution and improve air quality.
