Under the Dredging Operations and Environmental Research DOER program, diesel fuel additives were tested to evaluate their potential for reducing diesel fuel consumption and cost. Fuel usage was measured while using the additives with diesel fuel candidate tests and compared to fuel usage under the same conditions while using only standard diesel fuel baseline tests. The tests were conducted on diesel generator sets at the Corps Lock and Dam 4 Service Base ethanol injection in Alma, WI, the quarters boat Taggatz Envirofuels Diesel Fuel Catalyst located near Wabasha, MN, and the towboat Pathfinder DurAlt Fuel Conditioner and Lucas Fuel Treatment located in Saint Louis, Mo. The evaluations were conducted in the field under actual, in-use operating conditions. The results are applicable to the host engines and operating conditions, but similar results can be expected for similar engine families, year of manufacture, and operating regimes. While the additives showed limited fuel reduction in select operation conditions, only the ethanol injection system consistently showed potential to reduce diesel fuel consumption, which may be due to its higher injection volume.
