AHL-TECH has developed a new generation of greenhouse gas-reducing and efficient-to-operate ethanol-electric hybrid (internal combustion engine plus battery) railway locomotives that will be manufactured in a state-of-the art locomotive rebuild facility currently located in Iowa. AHL-TECH 1,000 to 4,000 HP locomotives are designed for use in railroad yards, industries, branch lines, or main lines where concerns about emissions are highest and a low to medium horsepower locomotive is suitable.
Ford made presentations to the Department of Energy and the Society of Automotive Engineers to update them on its development of a twin-fuel engine, code named Bobcat. Unlike flex-fuel engines that use a blend of ethanol and gasoline, the Bobcat engine uses gasoline and injects small amounts of ethanol when higher octane is needed to prevent fuel detonation. Ford’s engineering partner is Ethanol Boosting Systems, said that the “octane boost” system could realize up to 500 horsepower and 750 foot-pounds of torque from a 5.0 liter V-8 engine. In the boosting system, the vehicle would contain separate tanks for ethanol and gasoline.
Ricardo’s EBDI engine technology solves many of the shortcomings of current generation flex-fuel engines, which are typically only optimized for gasoline operation and do not make full use of the properties of ethanol. Unlike existing flex-fuel technologies EBDI takes full advantage of ethanol’s properties of high octane and latent heat of vaporization to deliver near-diesel levels of engine efficiency at substantially reduced cost.
