Exhaust Treatment

From the moment you start your Cayenne Diesel, innovative features intelligently apply clean diesel technologies.

As the exhaust gases exit the combustion chamber, they will travel through four separate processes— Exhaust Gas Recirculation, which reduces the formation of nitrogen oxides; the Oxidation Catalytic Converter, which converts pollutants such as carbon hydrates into less harmful substances; the Diesel Particulate Filter, which traps and eliminates the majority of particulate; and the Reduction Catalytic Converter, which converts the remaining nitrogen oxides to nitrogen and oxygen utilizing the AdBlue® agent.

These processes help to ensure the reduction of harmful pollutants into the environment and make the Cayenne Diesel compliant with U.S. emissions standards.
