EU-funded project develops diesel engine for light helicopters

Green Car Congress

EU-funded scientists developed a novel 320 kW (429 hp) diesel engine for light helicopters as an alternative to conventional turboshaft engines. Helicopters conventionally employ a turboshaft engine that has a much better power-to-weight ratio compared to diesel engines. —DELILAH final report.

ORNL researchers use stop-light cameras to reduce fuel consumption of less-efficient vehicles via traffic management

Green Car Congress

Approximately 6 billion gallons of fuel are wasted in the US each year as vehicles wait at stop lights or sit in dense traffic with engines idling, according to US Department of Energy estimates. —Tim Gee, principal computer vision engineer at GRIDSMART. That was a bit of an effort, too, but that’s what it’s all about.

liter Opposed-Piston Gasoline Compression Ignition (OPGCI) engine. The OP engine produces 270 hp and 480 lb-ft (651 N·m). The Achates Power Opposed-Piston (OP) Engine is engineered to achieve superior thermal efficiency by virtue of its lower heat losses, improved combustion, and reduced pumping losses.

Light duty RCCI can deliver engine-out Tier 2 Bin 5 NOx; potential for 52% gross indicated efficiency

Green Car Congress

A study by Sage Kokjohn, Senior Engineer in Combustion Research at Cummins Inc., Rolf Reitz of the University of Wisconsin found that reactivity controlled compression ignition (RCCI) ( earlier post ) in a light-duty engine can meet Tier 2 Bin 5 NO x levels without aftertreatment, while offering a 4% improvement in fuel consumption and 7.3%

MIT, NASA engineers develop morphing wing

Green Car Congress

A team of engineers has built and tested a radically new kind of airplane wing, assembled from hundreds of tiny identical pieces. By way of comparison, rubber has a density of about 1,500 kilograms per cubic meter. The research shows promise for reducing cost and increasing the performance for large, light weight, stiff structures.
