VW will be changing all it's diesels to adopt the common rail system starting from 2007. Right now VW uses in the TDI engines a direct fuel injection system (TDI=Turbo Direct Injection).

Yannis, can you tell me about VW's diesels?

What's better, TDI direct injection, or common rail? And what's with this Pumpe Duse thing I hear about? What does it relate to?

For what it's worth, I thought most other makers already have common rail diesels.
 
Common rail diesels have smoother operation and are more environmental friendly right now apparently. TDIs on the other hand were the first engines of all manufacturers to reach Euro 4 emission limits which gave them a significant advantage in some markets (eg. Germany, UK) cause euro 4 diesels had reduced taxes.
Since VW right now uses both systems (Direct injection mainly in smaller engines, common rail in larger) i believe that they want to adopt one standard to cut production and R&D costs.
