Eaton Corporation has received one of Nissan Motor Co.’s s “Global Innovation Award” for the Eaton TVS (Twin Vortices Series) supercharger used in the downsized DIG-S engine in the Micra. Eaton’s TVS superchargers feature patented high-speed rotors driven directly from the engine’s crankshaft. Earlier post.).
The all-new electronic limited slip differential, Ultra Posi is designed for front and rear-wheel drive vehicles, performs comparably to four-wheel-drive and all-wheel-drive systems and provides up to a 10% savings in fuel economy, Eaton says. —Chris Ostrander, vice president and general manager - Eaton Torque Controls.
Eaton announced it is contributing several components to truck manufacturers participating in the U.S. Eaton is supplying a number of leading-edge technologies that improve fuel economy and reduce emissions to Original Equipment Manufacturer (OEM) teams. Department of Energy’s (DOE) SuperTruck II program. Earlier post.).
V-Charge system with mechanical variable drive outperforms conventional boosting methods on downsized gasoline engine. This signals the potential for a new level of downsizing, enabling the industry to further reduce the CO 2 output of high volume vehicles without compromising driver satisfaction. Click to enlarge.
Eaton has announced its newest supercharger—TVS2—which improves vehicle manufacturers’ ability to deliver an optimal single boosted application, or to pair this device with other boosting technologies in order to deliver compound boosting solutions for improved engine performance—a combined supercharger-turbocharger system.
A new white paper published by the International Council on Clean Transportation (ICCT), in collaboration with Eaton, Ricardo, JCI, BorgWarner, Honeywell, and the ITB Group, analyzes current turbocharged, downsized gasoline engine technology developments and trends. Source: ICCT. Click to enlarge.
Eaton can help manufacturers meet these challenges by applying its years of experience and in-house capability in design, validation and manufacturing of high-precision, high-quality gearing systems for transmissions and powertrains. Eaton conducts a total system analysis, using state-of-the-art tools and.
This enables the boost of downsized engines to be completely controlled at any point on the operating cycle, including part-load. The chart to the right plots the measured performance of the BladeBoost against the latest Eaton R900 TVS supercharger, using the published map of thermal efficiency. Earlier post.).
To achieve the target fuel economy improvement over the baseline V6 configuration, the team used GTDI technology for downsizing in combination with part-load lean homogeneous charge compression ignition (HCCI) operation for further fuel economy gains. The project team is replacing a 3.6L I4 Ecotec engine. Wheeler, J., Polovina, D.,
The new engine will achieve high efficiency using the Atkinson Cycle with an 18:1 compression ratio, combined with aggressive engine downsizing. The engine will include new technologies developed by Envera and Tier-1 supplier Eaton. Eaton will provide a new advanced supercharger and variable valve actuation (VVA) technology.
Researchers from Southwest Research Institute (SwRI) and Eaton have demonstrated the application of downspeeding and supercharging a diesel vehicle, in conjunction with optimizing transmission gear ratios and the shift schedule, to deliver a greater improvement in fuel economy than a downsped and turbocharged configuration.
When presented with a list of technologies analyzed within a National Academies of Science report ( earlier post ) that might be used to meet fuel-efficiency standards, suppliers picked turbocharging and engine downsizing, along with higher-speed automatic transmissions, as the most critical.
The Southwest Research Institute and Eaton examined the issue. They showed that supercharging with downsizing can offer fuel economy gains by around 12.2 Downspeeding and supercharging while optimising the transmission; or downspeeding and turbocharging – which can offer the greatest fuel economy improvement?
The Freightliner SuperTruck uses a downsized and downsped 10.7-liter Hybrid: A123 Systems, Eaton, FUSO, ITK Engineering, Mercedes-Benz, MiaSole, US Hybrid. —Derek Rotz, principal investigator for SuperTruck, Daimler Trucks North America.
