 Workpackage 3: Multistage/Intelligent turbocharging
 

AIM: to examine multistage turbocharging providing charging pressures beyond today’s state of the art and to investigate the potential of variable geometry turbocharger
components and power take in / take out, in terms of wider operating range capabilities.

Objectives:

  • To investigate the potential benefit of variable geometry turbocharger systems, as well as systems with power take in/out and multi-stage turbochargers.
  • To develop and test prototype components on test-rigs as well as on lab engines.
  • To study and develop new concepts for variable turbocharging and to demonstrate the potential of the concepts by means of prototype and full-scale tests.

The Workpackage consists of two Tasks:

Task 3.1: Variable Turbocharging

Task 3.2: Intelligent Turbocharger
