ETI announces £2.5M lower drivetrain HDV efficiency project

July 27, 2012

The UK Energy Technologies Institute (ETI) has launched a three-year, £2.5-million (US$3.9-million) project to improve the efficiency of Heavy Duty Vehicles (HDV) by cutting the amount of parasitic losses in the lower drivetrain system by 50%. The ETI is a public-private partnership between global energy and engineering companies—BP, Caterpillar, EDF, E.ON, Rolls-Royce and Shell—and the UK Government.

Parasitic losses caused by the churning of the lubricating oil and component friction in HDVs and off-road vehicle drivetrains can account for more than 10% of overall vehicle energy losses. This project will look to improve the overall system design, with a synergistic focus on gears, bearings, surface treatments, lubricant flow and lubricant composition.
