(NYSE: CMI) announced the development of an engine and powertrain that reduce carbon dioxide (CO2) emissions by as much as 80 percent compared with a baseline gasoline-powered medium-duty truck. . . The Cummins ETHOS 2.8L is designed specifically to use E-85, a clean-burning blend of 85 percent ethanol and 15 percent gasoline. To take full advantage of the favorable combustion attributes and potential of E-85, the engine operates at diesel-like cylinder pressures and incorporates advanced spark-ignition technology. It delivers the power (up to 250 hp) and peak torque (up to 450 lb-ft) of gasoline and diesel engines nearly twice its 2.8-liter displacement . . . Using corn-derived E-85, the high thermal efficiency and power-to-weight ratio of this engine results in 50 to 58 percent lower well-to-wheels CO2 emissions compared with the gasoline engine baseline. Using second-generation lignocellulosic-derived E-85, the powertrain’s efficiency features deliver an impressive 75 to 80 percent lower well-to-wheels CO2 emissions, depending on the drive cycle. . .
