ABSTRACT
The necessity to be compliant to worldwide legislation in increasingly demanding CO2 reduction leads to improvements in ICEs power and efficiency. Therefore, recently the attention has been shifted on engine cycle modification, stochiometric combustion and on the increase of temperatures at turbine inlet of the turbocharging units.
In this presentation, the results of an experimental campaign, performed to check turbine wheel temperatures during real engine applications, will be discussed together with a description of the experimental setup.
These maps were employed to improve mathematical CFD models, which are the roots of a life assessment model that can track turbocharger health in real time, extending traditional operating ranges and improving overall engine efficiency.
