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.
V-Charge system with mechanical variable drive outperforms conventional boosting methods on downsized gasoline engine. These will include simulation using a GT-Power model and engine dynamometer testing which was carried out at the University of Bath Powertrain and Vehicle Research Centre (PVRC). 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.
Power management company Eaton’s Vehicle Group is developing gearing solutions for electrified vehicles (EVs). The new technology complements Eaton’s eMobility power electronics portfolio in the electrified vehicle powertrain market. 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 graphs below show the measured shaft power from Lontra’s test stand, with the BladeBoost variable inlet port set at its maximum and minimum opening: Measured shaft power. Earlier post.).
The new engine will achieve high efficiency using the Atkinson Cycle with an 18:1 compression ratio, combined with aggressive engine downsizing. To attain high power levels, new high-efficiency supercharging technology will be used to boost the engine and provide V8-like performance from only four cylinders. Earlier post.).
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 Freightliner SuperTruck uses a downsized and downsped 10.7-liter The SuperTruck’s AC system runs entirely off the electricity powered by the hybrid system. Solar panels run the length of the top of the SuperTruck’s trailer, helping to charge the hybrid battery, which in turn powers the eHVAC system. Click to enlarge.
