===== TDI =====

TDI stands for **T**urbocharged **D**irect **I**njection and a registered trademark of Volkswagen AG for its diesel engines.
That means turbocharged with direct diesel injection into the combustion chamber. Compared to prechamber or swirl chamber [[https://dieselschrauber.org/en/|diesel engines]] they are characterised by superior efficiency and thus higher performance with lower consumption.

All TDIs have electronic engine management via [[en:edc]] or control unit from [[delphi]] .
TDI engines are installed in vehicles from Audi, Cupra, Seat, Skoda and VW.
