Test Bench for Turbocharger Groups Characterization

The objective of this paper is to describe a turbochargers test bench capable of elaborating turbochargers maps, under pulsating or continuous flow conditions. With this experimental tool it is possible to obtain information about turbocharger performance at realistic engine operative points. Consequently, the experimental tool is able to complete and validate manufacturers turbochargers maps.

In order to deeply achieve these objectives, the turbocharger test bench is used in combination with a gas-dynamic code, which provides an accuracy simulation of the experimental installation. In addition, the obtained information will increase the power of modelling codes used for turbocharged engines design.
