PNNL team develops onboard fuel separation technology to enable octane-on-demand for improved fuel economy

Green Car Congress

Researchers at the US Department of Energy’s Pacific Northwest National Laboratory (PNNL) have developed an onboard separation system that could support increased fuel economy and lower greenhouse gas emissions as part of an octane-on-demand fuel-delivery system. Higher-octane fuels can eliminate knock but are expensive to produce.

U Wisc. study explores effects of biodiesel-gasoline blend in diesel engine

Green Car Congress

One high-efficiency combustion concept under investigation is gasoline compression ignition (GCI)—the use of gasoline-like fuels to deliver very low NO x and PM emissions as well as high efficiency in a diesel compression ignition engine. The commercially available gasoline base had an octane number of 87.

ExxonMobil, Corning and Toyota develop onboard membrane system to separate gasoline into octane fractions to optimize engine efficiency and performance

Green Car Congress

ExxonMobil, Corning and Toyota have collaborated to develop an Onboard Separation System (OBS) to optimize gasoline engine efficiency and performance. The system, say the researchers, offers the potential to exploit most of the benefits of operating on premium high octane fuel while using less expensive regular grade more effectively.

New technique for modeling auto-ignition characteristics of bioethanol-blended gasolines

Green Car Congress

Researchers at KAUST in Saudi Arabia, with colleagues from Saudi Aramco and the National University of Ireland Galway, have developed a new method for investigating the auto-ignition behavior of bioethanol-blended gasolines. Various gasoline surrogates, ranging from single to multi-components, have been proposed in the literature.

Study shows bamboo ethanol in China technically and economically feasible, cost-competitive with gasoline

Green Car Congress

Now, researchers at Imperial College London have shown that bioethanol production from bamboo in China is both technically and economically feasible, as well as cost-competitive with gasoline. In 2009, the number of private cars owned in China exceeded the United States, resulting in it being the world’s largest auto market.

MIT study: higher octane standard fuel in US could lower fleet fuel consumption & GHG an extra 4.5-6% by 2040

Green Car Congress

Offering a higher-octane gasoline to the consumer market in the US as the standard grade could deliver an incremental 4.5% to 6% reduction in fleet fuel consumption and greenhouse gas emissions by 2040, on top of a projected 26.8% to 6% reduction in fleet fuel consumption and greenhouse gas emissions by 2040, on top of a projected 26.8%
