New ETI project to increase heavy-duty vehicle efficiency

  • 24-Jul-2012 03:52 EDT

The Energy Technologies Institute (ETI), working with Romax Technology, Castrol Ltd., and ANSYS Inc., has announced a £2.5 million project to reduce parasitic losses and increase the efficiency of heavy-duty vehicles (HDVs). The project will focus on improving vehicles’ overall system design, including gears, bearings, surface treatments, lubricant flow, and lubricant composition. Parasitic losses in the lower drivetrain system can account for more than 10% of overall vehicle energy losses; the goal is to cut this loss by 50%. ETI plans to use the technologies developed in this project on a variety of HDVs, including buses, tractors, backhoe loaders, and wheeled loaders. “When we launched our HDV efficiency program, we stated a belief that HDV carbon dioxide emissions could be reduced by up to one-third,” said Chris Thorne, Program Manager for Heavy Duty Vehicles at ETI. “This next phase of the program aims to take us closer to that end objective.”
