diesel oxidation catalyst

A diesel oxidation catalyst (DOC) is a device used in diesel engines to reduce harmful emissions. It works by converting pollutants like carbon monoxide, hydrocarbons, and some nitrogen oxides into less harmful substances such as carbon dioxide and water. The catalyst, made of precious metals like platinum and palladium, facilitates chemical reactions as exhaust gases pass through it. This process helps improve air quality, meet environmental regulations, and reduce the engine's overall pollution footprint. The DOC is an essential part of modern diesel exhaust systems, ensuring cleaner emissions from diesel-powered vehicles and equipment.
