Researchers explore catalytic partial oxidation reformation of diesel, gasoline, and natural gas for “single-fuel RCCI”

Green Car Congress

Researchers at Stony Brook University, with colleagues from The City College of New Tyork, Alloy Surfaces and Innoveering, explored the catalytic partial oxidation (CPOX) reforming of three potential transportation-relevant fuels—gasoline, diesel, and natural gas—for use in low-temperature combustion (LTC) engines.

Fraunhofer ISI/ICCT analysis of PHEV data finds real-world CO2 emissions 2-4x higher than official values

Green Car Congress

As a result, the gap between official and real-world values is much larger for plug-in hybrid vehicles than for conventional combustion engine vehicles. As plug-in hybrid vehicles are equipped with a combustion engine as well as an electric motor, their potential for reducing emissions depends strongly on daily driving patterns.

RMI report finds substantial emissions reductions possible with smart EV charging

Green Car Congress

A new report from RMI has found that optimized charging of electric vehicles, which involves automatically and strategically shifting when an EV charges, could significantly reduce transportation sector emissions, and could potentially result in an average of 800 pounds of CO? saved per vehicle annually.
