ORLANDO, Fla. –Detroit Diesel’s use of turbo compounding on its DD15 engine has earned it the 2008 Truck Writers of North America (TWNA) Technical Achievement Award.
The award presentation was made at the annual Technology and Maintenance Council (TMC) meetings.
Chuck Blake, manager of senior technical sales support for Detroit Diesel, accepted the award on behalf of the company.
TWNA is a professional organization whose membership is composed of writers, editors, public relations specialists, marketing personnel and others involved in the business of creating or producing information related to the world of trucking. The organization has been presenting its Technical Achievement Award since 1991. Complete vehicles are not eligible, but systems and components are.
Detroit Diesel’s turbo compounding system employs a second exhaust turbine downstream of the standard turbo. In addition to providing a more efficient source of exhaust back-pressure for the engine’s EGR system, the secondary turbine’s output is hydronamically coupled to the engine’s drive gears.
“The committee was impressed by the DD15’s use of turbo compounding, which captures previously- wasted energy and converts it into productive power, improving fuel efficiency and performance. With diesel prices reaching unprecedented heights in 2008, we felt it was a technological advancement worthy of the award,” said committee chair, James Menzies of Truck News.
Press members of TWNA nominated products introduced in 2008 and a list of eight finalists was short-listed.
Finalists included: Bendix’s Adaptive Cruise Control; Cummins Westport’s ISL G Natural Gas Engine; Detroit Diesel’s DD15 Engine with Turbo Compounding; Eaton’s Hybrid- Electric System and Hydraulic Launch Assist System; Goodyear’s DuraSeal Trailer Tire; Great Dane’s CorroGuard Undercoating; and Meritor Wabco’s OnGuard Collision Avoidance System. •
