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). The study results, reported in the journal Fuel , demonstrated that the fuel composition has a significant on particulate emissions from GDI engines. Storey et al.

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. Vapor pressure can affect proper cold starting of the engine; vapor lock tendency in older engines without fuel injection; and quality of starting in engines with fuel injection.

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

Green Car Congress

The Brazilian experience shows that the presence of small (<10%) amounts of water in the fuel does not in itself cause a greater tendency to misfire in spark ignition engines than a proportionate leaning of the fuel/air mixture would do, provided that the vapor pressure of the hydrated ethanol at the ambient temperature is high enough.
