Study quantifies impact of fuel composition on PM emissions from gasoline direct injection engines

Green Car Congress

According to data released by the Beijing Environmental Protection Bureau (EPB) in 2014, motor vehicles were responsible for 31% of local PM 2.5 The GDI tailpipe particulates consist mainly of EC (elemental carbon), OM (organic matter) and small amounts of inorganic ions. emissions in 2014. 2015.11.019 Storey, J., Szybist, J.,

Study of Vapor Pressures of Gasoline-Alcohol Blends Finds That Dual-Alcohol Blends Can Result in RVPs Identical to That of Gasoline

Green Car Congress

RVPs (predicted DVPE) of single- and dual-alcohol blends in gasoline with different relative proportions of ethanol and 1-butanol. Evaporative emissions from gasoline—volatile organic compounds (VOCs)—are precursors to the formation of tropospheric ozone and contribute to ground-level ozone. Credit: ACS, Andersen et al.

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

Since the 1973 oil crisis, a plethora of books and instruction manuals have been published in the US on the subject of how to build small stills to produce inexpensive 192-proof alcohol (hydrous ethanol) to be used to blend with gasoline in motor vehicles. Until fairly recently, these US motor vehicles were non-FFVs.
