Gentherm to adapt passenger-car thermoelectric generator to heavy vehicles

01-Oct-2012 16:16 GMT

Gentherm has received a $1.55 million contract modification from the U.S. Department of Energy (DOE) to apply the technology in its thermoelectric generator (TEG) for passenger cars to a similar program for heavy vehicles. The TEG technology, which converts waste heat from gas exhaust into electric energy, has the potential to improve passenger-car fuel efficiency by as much as 5%, the company claims. The grant is an add-on to the $8 million award from the DOE in August 2011 for converting thermoelectric heat to power for passenger cars and extends the technology to heavy military vehicles. With this new project, the U.S. Army Tank Automotive, Research, Development and Engineering Center (TARDEC) becomes a key partner to Gentherm, joining passenger-car partners Ford and BMW. With completion expected by early 2015, the project will scale up the fully functional passenger-car TEG (working prototypes have been delivered to BMW and Ford) and integrate it with a 15-L diesel engine to provide fuel economy improvement and ignition-off auxiliary power for combat vehicles. This add-on leverages the existing program technology for large diesel engines, providing a new solution for military heavy vehicles, Class 8 trucks, marine, and industrial power generating equipment.

The three-cylinder D03CJ produces up to 41 kW (55 hp) and 165 N·m (122 lb·ft) at 1800 rpm. The four-cylinder D04CJ produces a maximum of 55 kW (74 hp) and 230 N·m (170 lb·ft) at 1800 rpm. Fuel efficiency is reportedly 16% better than the previous engines.

The new Tier 4 interim, four-cylinder D04EG (3.331 L) delivers up to 74 kW (99 hp) and 375 N·m at 1600 rpm, with a power density of 0.22 kW/L. Compared with the Tier 3 engine it replaces, the D04EG offers 12% improved fuel economy. To achieve Tier 4 final compliance in the 57- to 74-kW (76- to 99-hp) range, MHI currently plans to incorporate a selective catalytic reduction (SCR) system.

All three new engine models are equipped with high-performance turbochargers, manufactured at the same plant that the engines are produced. Combined with a new optimized common-rail system, the engines achieve an enhanced power density that increases output up to 50% compared with the previous Tier 3 compliant engines, MHI claims.

Allison and Dana license Fallbrook's NuVinci transmission technology

17-Sep-2012 02:02 GMT

Dana Holding Corp. and Allison Transmission will use Fallbrook Technologies' Continuously Variable Planetary (CVP) technology in new products under a "strategic relationship" announced by the three companies Sept. 13. Fallbrooks' NuVinci CVP is a traction-based class of continuously-variable transmission that is scalable and adaptable.  In the basic design, a set of rotating balls is located between the input and output components. Tilting the balls changes their contact diameters and varies the speed ratio. Compared to other current technologies, Fallbrook claims its is less complex, scales and packages more easily, and costs less to manufacture. Under the deal, Allison has exclusive rights to use the Fallbrook CVP technology to develop and commercialize primary drivetrain transmissions for Allison's end markets, which could include commercial vehicles, military applications, and certain off-highway and large stationary equipment. Under a separate agreement, Dana will hold an exclusive license to engineer and produce transmission components and other advanced powertrain solutions for passenger and certain off-highway vehicles in the end markets that Dana serves. For end markets Allison Transmission serves, Dana and Allison have signed a letter of intent to explore a strategic alliance through which Dana would exclusively manufacture transmission components with NuVinci CVP technology for Allison. Full-scale production of transmissions with NuVinci-equipped components in Dana's off-highway markets is expected within the next three to five years, while implementation in passenger and commercial vehicles is anticipated before the end of this decade.

New ETI project to increase heavy-duty vehicle efficiency

24-Jul-2012 19:52 GMT

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.”
