The Advanced Power Systems Research Center (APSRC) operates eleven internal combustion engine test beds, with dynamometers ranging from 5 to 745 kilowatts, for powertrain research, as well as additional test beds for educational purposes. The facilities offer a wide range of testing capabilities, including the ability for both motoring and absorbing operation and dynamic conditions. Flexible fuel systems accommodate the study of both gaseous fuels and liquid fuels (alcohol blends, biodiesel, and green fuels). Conditioned combustion air supply systems capable of temperature, pressure, and humidity control are being integrated into several of the test cells, which are equipped with sophisticated powertrain instrumentation:
- AVL and ACAP equipment, for real-time combustion analysis
- Five gas analyzers, AVL FTIR, a mass spectrometer, Cambustion fast CO/CO2, Cambustion fast HC, PM mass and particle size, all for measuring emissions
- Embedded control with rapid-prototyping capabilities, and calibration with ETAS
- Coriolis and positive displacement meters and Laminar Flow Elements, for fuel and air measurement
- High-speed, high-channel-count DAQ, to accommodate various needs such as noise, vibration, and harshness testing
The center offers a suite of additional, highly specialized pieces of equipment for engine testing, including infrared and microwave telemetry systems, vehicle and component-scale environmental chambers for engine cold-start tests, and vehicle chassis dynamometers.
