Aramco, KAUST team finds hybrid gasoline compression-ignition architecture can reduce GHG 26-55% vs. conventional SI

Green Car Congress

Researchers from Saudi Aramco and KAUST (King Abdullah University of Science and Technology), with a colleague from Shanghai Jiao Tong University in China, assessed the effects of adopting 4 hybrid architectures on the life-cycle GHG emissions of a novel high-reactivity fuel in an advanced compression-ignition engine (GCI).

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

Green Car Congress

In a paper being presented at WCX SAE World Congress Experience in Detroit this week, a team from MIT is proposing the use of a flex-fuel gasoline-alcohol engine approach for a series-hybrid powertrain for long-haul Class 8 trucks. Ethanol or methanol would be employed to increase knock resistance. —Daniel Cohn.

Study finds GHG emissions from corn ethanol now 46% lower than gasoline

Green Car Congress

A new study by a team from Environmental Health & Engineering (EH&E) has found that greenhouse gas emissions from corn ethanol are 46% lower than those from gasoline—a decrease in emissions from the estimated 39% done by previous modeling. gCO 2 e/MJ) which is 46% lower than the average carbon intensity for neat gasoline.

Emissions Analytics: mass adoption of hybrids, rather than low-volume BEVs most effective for cutting CO2 now, meeting 2030 targets; best use of limited resource

Green Car Congress

Emissions Analytics, a leading independent specialist for the scientific measurement of real-world emissions, suggests that mass adoption of hybrid vehicles, rather than low-volume take-up of full BEVs, is the most effective solution to cutting CO 2 now and also in meeting 2030 emission targets. With a reduction of 73.9g/km/kWh,
