Design and Implementation of a New Generation of Turbo Charger Test Benches Using Hot Gas Technology

Test benches equipped with hot gas generators are used for the development and optimization of turbochargers. The main component of a new turbocharger test system is a double fluted hot gas generator. This generator has the precision and flexibility to keep the temperature at the turbine inlet at a constant level and to guarantee constant mass flow and uniform pressure. The overall test system functions fully automatically.

In what follows, we describe the construction of the new turbocharger test bench and the equipment necessary for operating turbocharger test benches in the context of an R&D test center. The control and automation system permits fully automatic operation.
