     this paper presents a new representation of the turbine performance maps oriented for turbocharger characterization. the aim of this plot is to provide a more compact and suited form to implement in engine simulation models and to interpolate data from turbocharger test bench.

    the new map is based on the use of conservative parameters as turbocharger power and turbine mass flow to describe the turbine performance in all vgt positions. the curves obtained are accurately fitted with quadratic polynomials and simple interpolation techniques give reliable results.

    two turbochargers characterized in an steady flow rig were used for illustrating the representation. after being implemented in a turbocharger submodel, the results obtained with the model have been compared with success against turbine performance evaluated in engine tests cells. a practical application in turbocharger matching is also provided to show how this new map can be directly employed in engine design.
