Turbocharger efficiency, and emissions reduction, turbochargers must be optimized for efficiency and matched to the specific engine. Southwest Research Institute (SwRI) maintains a state-of-the-art test facility in which turbochargers can be tested without the added complexity of an engine test cell setup.Turbocharger
SwRI is able to test turbochargers in ways not possible on an engine, including component and durability tests. Tests are conducted to SAE J1826, 揟urbocharger Gas Stand Test Code,?standards.Turbocharger
Compressor performance map Turbocharger
The SwRI Turbocharger Test Facility offers the following features:Turbocharger
Turbochargers can be fully mapped, generating compressor and turbine flow, pressure ratio, Turbocharger and efficiency maps.Turbocharger
An air factory produces pressurized and heated air to the turbine inlet at up to 1.0 kg/s, 1,400 kPa, and 600 degrees C (2,000 cfm, 200 psi, and 1,100 degrees F).Turbine shaft
Throttles on the turbine inlet and compressor outlet control turbo speed and pressure ratios.

Schematic of the turbocharger test facility
A lubrication system supplies heated and pressurized oil to the turbocharger.
A PC-based data acquisition system records speeds, airflows, temperatures, and pressures.
Turbocharger parameters are calculated in real time and recorded with measured data.
