KALAMAZOO, MI — International Truck and Engine Corp. and Eaton Corp. have been selected to manufacture diesel-electric hybrid trucks for a national pilot program serving the utility industry. The program is the largest in the nation to date and will test a minimum of 20 factory-built International utility trucks featuring an integrated hybrid powertrain solution jointly developed by the two companies.
The program was announced at the Hybrid Truck Users Forum (HTUF) operated by WestStart, an advanced technology consortium bringing together truck fleet users, truck makers, technology companies and the U.S. military. WestStart will be administering the pilot program through the support of the U.S Army’s National Automotive Center, the Army’s official link to working with commercial and academic partners. The center’s director, Dennis Wend, believes diesel-electric hybrid technology built on a commercial truck platform will benefit utilities and other commercial customers and can be rapidly transferred to military applications.
Both International and Eaton believe that diesel-electric hybrid technology holds significant promise. If the pilot program is successful and customer needs are met, International is prepared to produce diesel-electric hybrid trucks as early as 2006.
The initial powertrain will couple an International DT 466 in-line six-cylinder diesel engine with an Eaton hybrid-electric drivetrain, incorporating a transmission, batteries and permanent magnet motor. Power from the engine is converted directly into electrical energy, which then incorporates the conventional drivetrain to power the truck. The system recovers kinetic energy during braking, charging the batteries while the truck is slowing down. This provides additional power for acceleration, making the hybrid trucks ideal for in-city driving situations with frequent starting and stopping. Additionally, the hybrid truck used in the pilot will operate the utility bucket in an electric-only mode, with the engine shut off, for up to 2 hours and provide electric power during idling for added fuel saving benefits.
The diesel-electric hybrid test vehicles, which are International 4000 Series medium trucks, will be manufactured at International’s Springfield, Ohio, truck assembly plant. The International Dealer Network, along with a team of specialists from both International and Eaton, will provide field support for the units.
