Clean issue: the Volkswagen „Clean TDI“
Volkswagen unveils the cleanest ever TDI engine – the „Clean TDI“. Central theme of the entire concept is the reduction of nitrogen oxide. One of the drive systems, for example, uses a reservoir catalytic converter. Compared to present vehicles, this system produces up to 90 % less nitrogen oxide emissions. The “Clean TDI” engines of Volkswagen will comply with the most stringent requirements worldwide – the “Tier 2 /Bin 5” norm in the USA.
