Hydrogen Opposed Piston Engine Working Group formed

Green Car Congress

Several organizations, encompassing companies, research labs, and academia, have formed the Hydrogen Opposed Piston Engine Working Group. The Working Group consists of members undertaking research and development in the field of hydrogen combustion in an opposed-piston engine. If hydrogen combustion is sufficiently lean—i.e.,

NIST Characterizes -valerolactone Blends in Gasoline and Diesel

Green Car Congress

The additive shifts the distillation curve for diesel fuel to lower temperatures, with most of the additive removed from the mixture by the 40% distillate volume fraction. The presence of up to 2.5% (v/v) of γ-valerolactone in diesel fuel does not appear to affect the volatility to any great extent. —Bruno et al.

UW Madison, ExxonMobil researchers convert alcohols to diesel-range ethers and olefins

Green Car Congress

Researchers from the University of Wisconsin Madison and ExxonMobil Research and Engineering have devised a two-stage process by which an alcohol such as ethanol or 1-butanol can be converted with high yields into distillate-range ethers and olefins by combining Guerbet coupling (the coupling of two alcohol molecules) and intermolecular dehydration.
