Volkswagen TDI Clean Diesel engines are notably different in two ways: the fuel injection system, which sprays fuel directly into the combustion chamber, and the emissions control system, which adds a self-cleaning filter to trap and burn off nitrous oxides (NOx). Thanks to the size of its engine, the Touareg TDI also uses a urea-injection system to reduce NOx. Learn more about the Touareg TDI.
