 Workpackage 1: Extreme design parameters

AIM: to increase engine power density and combustion cycle efficiency to drastically higher level than today?s state-of-the-art. This will be performed by developing compression ignition engines designed for efficient and environmentally friendly operation under extreme working conditions.


  • To create general knowledge about a diesel engine operating under extreme thermal and mechanical load
  • To study the influence of advanced working cycles on engine performance and emissions
  • To find design and material solutions to overcome the problems caused by the extreme conditions with regard both to mechanical and thermal load
  • To develop new components and integrate them on engines
  • To perform full-scale tests to evaluate the developed technologies

The Workpackage consists of two Tasks:

Task 1.1: Mechanics of engine with extreme design parameters

Task 1.2: Thermodynamics of engines with extreme design parameters
