Teil 2: Thermodynamik

  • 32 Accesses


Part 1 dealt with the design and mechanical features of the V6 TDI engine [1]. This second part describes the thermodynamic development work that was necessary to comply with the extremely stringent Euro 4 exhaust emission limits in a large luxury car. The ambitious target of a power output of 132 kW from a displacement of 2.5 litres while remaining within the Euro 4 limits was achieved by adopting new or further optimised exhaust emission reduction techniques.
