	One of  more than 30 engine dynamometer evaluation bench stands used to gather data for engine combustion research

With more than 30 developmental steady-state engine dynamometer evaluation stands, Southwest Research Institute (SwRI) conducts sophisticated emissions reduction programs for future engines. SwRI also has transient-capable test stands and light-duty chassis dynamometers supported by certification-quality equipment.

Engine Evaluation Parameters

Up-to-date instrumentation in our engine laboratories is used to evaluate engines ranging from small generator engines to large marine and locomotive powerplants. SwRI measures a wide range of engine parameters, including:

• Performance

• Gaseous emissions

• Particulate emissions via full or partial dilution

• Smoke or opacity

• Tapered element oscillating microbalance—real-time particulate indicator

• Particulate size distribution

• Heat rejection

• Turbocharger performance

• Fuel injector performance

For more information about our engine evaluation capabilities, or how you can contract with SwRI, please contact Darius Mehta at dmehta@swri.org or (210) 522-2617.
