Simulation study suggests ORC waste heat recovery system could deliver potential 7% improvement in fuel consumption in a PHEV on highway

Green Car Congress

The analysis used the Ohio State University EcoCAR, a student prototype PHEV, as the basis for the preliminary fuel economy evaluation. The OSU EcoCAR PHEV powertrain. The OSU EcoCAR prototype vehicle features an extended-range electric architecture with a downsized 1.8L Exhaust gas exergy map of EcoCAR engine.

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. Their open access paper is published in the journal Energy.

PHEVs Are A Great Solution For Many — But PHEV Incentives Need Fixing

EV Adoption

Like many issues and discussion topics today, plug-in hybrid electric vehicles (PHEVs) have become a divisive concept within the electric vehicle industry. People seem to either be fans of the dual-powertrain approach of PHEVs or have a huge disdain for them. The Knocks Against PHEVs. Black and white.

MIT team proposes flex-fuel gasoline-alcohol engine PHEV long-haul trucks

Green Car Congress

In addition, by using a flex-fuel configuration that allows it to run on gasoline, ethanol, methanol, or blends of these, such engines have the potential to emit far less greenhouse gas than pure gasoline engines do, and the incremental cost for the fuel flexibility is very small, Cohn and Bromberg say. —Daniel Cohn.

Obama orders GHG cuts for Federal Agencies; 50% of all new agency vehicles to be ZEV or PHEV by 2025

Green Car Congress

President Obama today signed a wide-ranging executive order mandating cuts in greenhouse gas emissions for Federal agencies. Through more efficient Federal operations, agency direct greenhouse gas emissions can be cut by at least 40% over the next decade, the order suggests.
