Pumpe Duse
In 1999, Volkswagen introduced what would become one of the most well known engine designs of modern times - the Pumpe Duse (PD) diesel engine.

How does a PD injector work?
Unit-injection (VAG PD) piezo injector - voltage and current
The injectors are unlike common-rail injectors in that the high fuel pressure is generated by an additional rocker-arm running from the camshaft and acting directly on the injectors to compress the fuel, so there is no high-pressure pump. This action generates between 1,800 and 2,050 bar of pressure.
