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

Green Car Congress

Researchers from Tsinghua University and Peking University have investigated the effects of fuel properties on particulate emissions gasoline direct injection engines (GDI). Higher aromatics in gasoline resulted in much higher PM (mass), PN (particle number) and PAHs emissions, with higher toxicity to human health. emissions in 2014.

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. As part of the study, they demonstrated a simple method to prepare dual-alcohol-gasoline blends with Reid vapor pressures (RVPs) “ indistinguishable ” from that of the base gasoline.
