Cummins progressing with lightweight downsized T2B2 diesel for pickup; 40% improvement in fuel economy over gasoline V8

Green Car Congress

In 2013, the Cummins-led team demonstrated a Tier 2 Bin 5 version of the engine on the dyno, and then on a vehicle, while development of the Tier 2 Bin 2 engine started. Cummins made extensive use of aluminium as well as space-saving design features for new engine weight control. 6(2):372-381 doi: 10.4271/2013-01-0535.

Google and IEEE launch $1M challenge for downsized inverters

Green Car Congress

Google and the IEEE have launched the Littlebox Challenge—an open competition to design and build a small kW-scale inverter with the highest power density (of at least 50 W/in 3 , or 3.05 USABC Electrical and Electronics Technical Team Roadmap (June 2013). kW/L) in an enclosure of less than 40 in 3 in volume (0.66L).

Ford displays prototype Carbon Fiber Reinforced Plastic hood

Green Car Congress

Funded by the German state of North Rhine-Westphalia, the project began in 2010 and is scheduled to continue until September 2013. There are two ways to reduce energy use in vehicles: improving the conversion efficiency of fuels to motion and reducing the amount of work that powertrains need to do. Earlier post.)

Researchers propose evaluating alt fuel efficiency based on energy rather than volume; impact of ethanol on vehicle efficiency and GHGs

Green Car Congress

This is because the ethanol component may affect the conversion efficiency of the gasoline component in a blend, that is, make an engine more or less efficient in its use of the gasoline component.
