The Heavy-Duty Engine Benchmarking Program at Southwest Research Institute (SwRI) is designed to test and characterize competitive engines to assess their performance, emissions, efficiency and technology. The results of this program include data of great interest to companies that manufacture or use heavy-duty engines, components or emission aftertreatment systems.

Competitive benchmarking is a standard practice among engine, vehicle and component manufacturers. Comparative testing of new products is of great value for evaluating state-of-the-art technology, and SwRI is well known for its ten year program of engine benchmarking for heavy-duty engines. This heavy-duty engine benchmarking program is of particular relevance because of new emissions aftertreatment and efficiency improvement technologies continually being introduced. Diesel, natural gas and other alternative fuel heavy-duty engine variants are also evaluated.
