Abstract
In order to reproduce the unsteady turbocharger-turbine inlet conditions generated by an engine at a hot-gas test bench, a novel pulse generator unit (PGU) has been developed. This PGU modulates pressure-oscillations to the turbocharger intake-flow and is designed to work continuously in tough industrial environment. It consists of a circular throttle, which is rotated with non-uniform velocity in order to modify the shape and the frequency of the pressure oscillation. In this paper, the design and first experimental results of the PGU are presented. The focus lays on generating close-to-engine operating conditions for the turbine in an engine operating range below 2000 min-1. Therefore, the shapes of the pressure curves and their dependence of the pulse frequency are investigated in detail.
