Abstract
A method for extending thermodynamic turbine mapping of a turbocharger, the turbocharger including a turbine and a compressor, the method including the steps of providing a steady-state turbocharger gas test stand configured to flow continuous gas to the turbocharger, the test stand including a throttle device disposed upstream of an inlet of the compressor of the turbocharger, and varying an area of the inlet with the throttle device to change density of the continuously flowing gas at the inlet of the compressor and establish a choked-flow condition for extending the thermodynamic turbine mapping of the turbocharger.
