Southwest Research Institute will develop and demonstrate dedicated exhaust gas recirculation on a heavy-duty natural gas engine. The project involves research and development consisting on modifying a Cummins Westport ISX12G to operate with dedicated exhaust gas recirculation, advanced ignition systems, and an optimized turbocharger to demonstrate an increase in engine efficiency while maintaining near-zero emissions. The testing will be conducted in a 40 CFR Part 1085 compliant heavy-duty engine test cell.
