UC Riverside team characterizes impact on PM of fuels with varying aromatics and octane rating; benefit of increased ethanol fraction

Green Car Congress

Among their findings is that an increased ethanol fraction in gasoline could help reduce PM mass and black carbon (BC) from gasoline direct injection engines (GDI). Vehicle steady-state testing showed that the hygroscopicity of PM emissions at high speeds (70 mph; κ > 1) are much larger than emissions at low speeds (30 mph; κ.
