SwRI helps develop implement and verify state-of-the art emission controls for locomotives.

With a history of 50 years of experience in the automotive industry, Southwest Research Institute (SwRI) conducts heavy-duty alternative fuel evaluations and diesel engine development programs for all types of production and research. Engine development programs range from small two-stroke to large-bore two-to four-stroke engines used for vehicular, off-road, locomotive, marine, and other applications.

  • Conventional, alternative fuels, additive effects on emissions
  • Engine and emission control performance
  • On-highway diesel engines
  • Non-road and European diesel engines
  • Spark-ignited off-highway engines
  • Emissions sampling
  • Chassis testing of heavy-duty vehicles
  • Retrofit evaluation for system development
  • Component development and evaluation

Other Applications:

  • Locomotives
  • Stationary power plants
  • Gas compressors
  • Marine engines
  • Offshore drilling
  • Power generation
  • Engine performance improvement
  • Engine and component design
  • Fuel injection system development
  • Aftertreatment
