New split-cycle concept to control diesel HCCI combustion

Green Car Congress

A team from Universita degli Studi di Pisa (Italy) and Rolf Reitz at the University of Wisconsin-Madison are proposing a novel combustion concept—Homogenous Charge Progressive Combustion (HCPC)—based on a split-cycle principle to control HCCI combustion in diesel-fueled engines. —Musu et al., SAE 2010-01-2107.

EU investing >€3M in research into ultra-efficient aero engines; ULTIMATE project

Green Car Congress

The 3-year project, which launched in September 2015, targets radical concepts for new aero engines, in line with the EU’s long-term emissions reduction target for 2050. From the engine perspective two routes to radically improved fuel efficiency are being explored; ultra-efficient low pressure systems and ultra-efficient core concepts.

ORNL Research Project Seeks to Boost Combustion Engine Efficiency To 50-60% By Reducing Combustion Irreversibility; RAPTR

Green Car Congress

RAPTR is being designed to investigate R egenerative A ir P reheating and T hermochemical R ecuperation concepts for reducing losses from combustion irreversibility. The modified approach incorporates two main concepts— Regenerative Air Preheating (RAP) and Thermochemical Recuperation (TR)—resulting in the acronym RAPTR. Stuart Daw.

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.

EADS demonstrating electric and hybrid aviation propulsion; innovative distributed propulsion series hybrid

Green Car Congress

E-Thrust is a “series hybrid” electrical distributed propulsion system concept using one gas power unit providing the electrical power for six fans for lower fuel consumption, fewer emissions and less noise. EADS is also cooperating with Rolls-Royce on a future distributed propulsion system concept (DEAP) for full-size passenger aircraft.
