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. The technology demonstrated substantial reductions in fuel consumption and emissions. The engine weight is the crux of the project.

NPC report to Energy Secretary finds light-, medium- and heavy-duty vehicles could reduce per-mile GHG at least 40% by 2050; additional strategies required for further reductions

Green Car Congress

Projected range of impact of demand, fuel efficiency improvements, and alternative fuel-vehicle systems on light-duty fleet GHG emissions. On a stand-alone basis, all light-, medium-, and heavy-duty vehicles have the potential to reduce per-mile GHG emissions by at least 40% in 2050, relative to 2005 average fleet levels.

EIA projects decline in transportation sector energy consumption through 2037 despite increase in VMT, followed by increase

Green Car Congress

For the Transportation sector, EIA projects that energy consumption will decline between 2019 and 2037 (in the Reference case) because increases in fuel economy more than offset growth in vehicle miles traveled (VMT). Light-duty vehicle miles traveled increases by 20% in the Reference case, growing from 2.9

ICCT-sponsored study of in-use testing of 3 Tier2-Bin5, CA LEV-II light-duty diesels finds wide variation of emissions against the limits

Green Car Congress

In-use testing of three light duty diesel vehicles—certified to US-EPA Tier2-Bin5 and California LEV-II ULEV emissions limits— found a wide variation in real world emissions performance relative to the regulatory limits. Overall, urban/suburban driving leads to a 32-39% reduction in fuel economy over highway driving.
