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

Green Car Congress

At the US Department of Energy’s (DOE’s) Annual Merit Review meeting in Washington, DC last week, Michael Ruth from Cummins noted that the DOE program target for the project is a fuel economy (CAFE) target of 26 mpg (9.05 Earlier post.). l/100 km), and as such would not meet the GHG requirement of 28 mpg (8.4

Review of research suggests inconclusive support for fuel consumption benefits of catalyzed EGR

Green Car Congress

Conflicting evidence does not support making a firm conclusion on the fuel consumption benefit of catalysed Exhaust Gas Recirculation (EGR), according to a review of current studies by a team at the University of Bath (UK). According to the review, the conversion of HCs, CO, and NO in the exhaust gas by the catalyst can result in up to a 4.5%

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

Green Car Congress

In a policy analysis in the ACS journal Environmental Science & Technology , researchers from the Universities of Cambridge, Exeter and Oxford argue that, due to the increased emphasis on alternative fuels with drastically differing energy densities, vehicle efficiency should be evaluated based on energy rather than volume.

Conversely, short bursts of power can also be absorbed by the SpeedStart generator to recharge the battery during vehicle decelerations. Small displacement engines offer excellent CO 2 and fuel economy benefits; they have lower parasitic losses and operate more efficiently under part load conditions.

GMZ-led project tracking to deliver vehicular thermoelectric generators for Bradley Fighting Vehicle, Honda Accord

Green Car Congress

GMZ Energy, a provider of advanced nano-structured thermoelectric generation technology, was co-founded by MITs Professor Gang Chen and collaborator Zhifeng Ren of the University of Houston. An automotive TEG is intended to improve fuel economy by power from waste heat to reduce the electric generator load on the engine.
