Rolls-Royce to power U.S. Navy’s new Ship-to-Shore Connector hovercraft fleet
Rolls-Royce won a contract to power the U.S. Navy’s future fleet of hovercrafts, known as the Ship-to-Shore Connector (SSC). It will work with Textron Marine & Land Systems, which has been selected to build the initial development craft, in a program that could extend to 73 craft. The SSC will replace the Navy’s current fleet of Landing Craft Air Cushion (LCAC) hovercraft over the next 20 years. The new hovercraft will be used to rapidly deploy personnel and vehicles between U.S. Navy ships and the shore. Each SSC will use multiple Rolls-Royce MT7 gas turbines, derived from the AE1107 engine, which powers the U.S. Marine Corps ’ V-22 Osprey tilt-rotor aircraft. Rolls-Royce will also design and manufacture the air intake and exhaust systems.

Gentherm to adapt passenger-car thermoelectric generator to heavy vehicles
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.

Navistar, JAC one step closer to Chinese engine joint venture
Navistar International Corp. and Chinese truck maker Anhui Jianghuai Automobile Co. Ltd. (JAC) recently received formal approval from China’s National Development and Reform Commission (NDRC) to move forward with their commercial-engine joint venture, first announced in September 2010 when the companies signed an agreement. The JV will provide JAC with access to Navistar’s Euro IV and Euro V compliant technology, and also sets the stage for global export opportunities of JAC’s light-, medium-, and heavy-duty commercial trucks. Navistar has established a central China office in Shanghai, as well as satellite offices in Beijing and Hefei. In Hefei, product development engineers from both companies have been collaborating on engine and vehicle design. Construction also has started on a 93,000-m2 (1 million-ft2) machining and assembly facility, R&D center, and administrative offices in Hefei to support the new venture. Products slated for the JV include Navistar’s MaxxForce 3.2-, 4.8-, and 7.2-L, and JAC’s 2.8-L 4DA1 engines. Now that the JV has received its business license, Navistar and JAC planned to formally submit their commercial truck joint venture application to the Chinese government this fall.
ZF, LiuGong cooperate on modular axle concept for China
ZF and construction equipment manufacturer LiuGong recently formed a new joint-venture axle company, called ZF Liuzhou Axle Co. Ltd., that will produce wheel loader axles tailored to the requirements of the Chinese market. The companies expect that by 2018, approximately 190 employees will work at ZF Liuzhou Axle and that more than 30,000 of the newly designed axles will be delivered to LiuGong and the third market. ZF and LiuGong have been operating a JV company in Liuzhou since 1995, producing construction machinery transmissions and axles; the new JV was launched in the same location. “A team of engineers from ZF Headquarters, LiuGong, and ZF China have been working together to upgrade the existing axle models for LiuGong wheel loaders since October 2011,” said Hermann Beck, head of the ZF Business Unit Off-Highway Systems. “These joint efforts brought about a modular axle concept which, besides the standard version with dry disk brake (Basic Line), offers the possibility to supply a new, even more sophisticated technical solution with wet multi-disk brake (High Line) using a large portion of common parts.” ZF expects this modular concept to greatly reduce production costs. About 3300 newly designed axles are scheduled to leave the Liuzhou production plant in 2014.
Tier 4 small diesels coming from MHI
Mitsubishi Heavy Industries, Ltd. (MHI) has announced the production schedule for its new Tier 4 small diesel engines in the output range of 19 to 74 kW (25 to 99 hp). The Tier 4 compliant D03CJ and D04CJ will begin production in 2013; the Tier 4 interim D04EG is currently available, and the Tier 4 final version will be available in 2015. These engines will be suitable for a variety of construction, agricultural, and industrial equipment, such as compressors, generators, welders, off-highway equipment, material handling, etc.
Compared to the previous Tier 3 compliant models being replaced, the D03CJ (1.655 L) and D04CJ (2.207 L) offer a smaller displacement, while output has been increased. 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.

The D03CJ (pictured) and D04CJ both feature an optimized common-rail system with a diesel particulate filter (DPF) and diesel oxidation catalyst (DOC) for Tier 4 compliance.
Allison and Dana license Fallbrook's NuVinci transmission technology
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.
Eaton, NREL team to reduce hybrid-electric-vehicle battery size
Eaton Corp. is developing a power control system for hybrid-electric vehicles (from passenger cars to commercial vehicles) with the goal of reducing by 50% the size of the battery needed. The company on Aug. 27 announced that the work is part of a $2.8 million project funded jointly by Eaton and the U.S. Department of Energy, the latter of which is contributing $2 million. The project is being led by Eaton's Innovation Center team in Southfield, MI, which will work with a team from the DOE's National Renewable Energy Laboratory (NREL)—the former offering expertise in intelligent power management and the latter expertise in battery modeling and prognostics. Specifically, the project aims to significantly downsize the battery through a combination of duty-cycle learning and model-based supervisory optimal control design. Using advanced physics-based battery models developed in partnership with NREL, the hybrid vehicle supervisory controller dynamically balances fuel economy and the health of the downsized battery pack to maximize vehicle performance while minimizing the impact on battery life.
