Title: Impact of ethanol blending on particulate emissions from a spark-ignition direct-injection engine

Abstract

Particulate formation due to combustion of a wide range of ethanol-gasoline blends was investigated in a spark-ignition direct-injection (SIDI) engine. This study is a follow-up to a previous study done by the authors in which particulate formation for ethanol-gasoline blends was examined under fully premixed combustion, eliminating physical effects of the fuel. In this study, fuel was injected directly into the cylinder to investigate how the physical properties of the blended fuels influence particulate formation. The engine was operated at a fixed load, phasing, and equivalence ratio while end of injection timing was varied. The results of this work show that increasing ethanol content leads to a decrease in engine-out particulate in spite of, sometimes significant, changes in fuel properties. However, it was also shown that particulate results can be affected by engine operating history which, if not taken into account, could have implications for research and real world applications.

Relative particle emission tendencies of 2-methyl-3-buten-2-ol–gasoline, isobutanol–gasoline, and ethanol–gasoline blends from premixed combustion in a spark-ignition engine

Journal Article Sakai, Stephen ; Rothamer, David - Fuel

Critical sooting equivalence ratios and subsequent particulate formation during spark-ignition combustion were studied for blends of ethanol, isobutanol (2-methyl-1-propanol), and methylbutenol (2-methyl-3-buten-2-ol) with gasoline using premixed prevaporized (PMPV) fueling. The air–fuel mixture was supplied to the engine in a well-mixed gaseous state allowing the chemical sooting tendency of the fuels, as measured by the critical sooting equivalence ratio, to be quantified. The engine was operated at a fixed load and phasing with varying equivalence ratio to determine the critical sooting equivalence ratio and evolution of the particle size distribution (PSD) for each fuel.

Ethanol Blend Effects On Direct Injection Spark-Ignition Gasoline Vehicle Particulate Matter Emissions

Conference Storey, John Morse ; Lewis, Sr, Samuel Arthur ; Barone, Teresa L

Direct injection spark-ignition (DISI) gasoline engines can offer better fuel economy and higher performance over their port fuel-injected counterparts, and are now appearing increasingly in more U.S. vehicles. Small displacement, turbocharged DISI engines are likely to be used in lieu of large displacement engines, particularly in light-duty trucks and sport utility vehicles, to meet fuel economy standards for 2016. In addition to changes in gasoline engine technology, fuel composition may increase in ethanol content beyond the 10% allowed by current law due to the Renewable Fuels Standard passed as part of the 2007 Energy Independence and Security Act (EISA).

Knock-limited combustion of ethanol-, isobutanol-, and 2-methyl-3-buten-2-ol-gasoline blends in a direct-injected spark-ignition engine

Journal Article Sakai, Stephen ; Rothamer, David - International Journal of Engine Research

Knock-limited combustion of alcohol-gasoline fuel blends was studied in a direct-injection spark-ignition engine. Ethanol, isobutanol (2-methyl-1-propanol), and methylbutenol (2-methyl-3-buten-2-ol) were splash-blended with a blendstock for oxygenate blending (BOB) gasoline. Ethanol was blended in fractions of 10%, 20%, and 30% by volume (E10, E20, and E30). Isobutanol and methylbutenol were blended to match the oxygen weight percentage of the ethanol blends, resulting in blends of 16%, 32%, and 49% (I16, I32, and I49) isobutanol by volume and 18%, 37%, and 56% (M18, M37, and M56) methylbutenol by volume.

Measured and Predicted Vapor Liquid Equilibrium of Ethanol-Gasoline Fuels with Insight on the Influence of Azeotrope Interactions on Aromatic Species Enrichment and Particulate Matter Formation in Spark Ignition Engines

Conference Ratcliff, Matthew A ; McCormick, Robert L ; Burke, Stephen ; ...

A relationship has been observed between increasing ethanol content in gasoline and increased particulate matter (PM) emissions from direct injection spark ignition (DISI) vehicles. The fundamental cause of this observation is not well understood. One potential explanation is that increased evaporative cooling as a result of ethanol's high HOV may slow evaporation and prevent sufficient reactant mixing resulting in the combustion of localized fuel rich regions within the cylinder. In addition, it is well known that ethanol when blended in gasoline forms positive azeotropes which can alter the liquid/vapor composition during the vaporization process. In fact, it was shown recentlymore »« less

Modeling Ethanol-Blend Fuel Sprays under Direct-Injection Spark-Ignition Engine Conditions

Journal Article Cheng, A. S. "Ed" ; Ratcliff, Matthew A. ; McCormick, Robert L. - Energy & Fuels

Computational modeling of fuel-injection and fuel-impingement processes was carried out to provide insight into previous experimental results obtained from a direct-injection spark-ignition research engine operated with various ethanol and aromatic fuel blends. Seven model fuels were evaluated using both single- and split-injection strategies. Model results showed that droplet vaporization enriched the concentrations of aromatic species in the liquid phase, especially those with low vapor pressure, and ethanol-containing fuels altered droplet sizes and led to increased liquid-phase mass in the cylinder. For the spray-modeling conditions studied, most of the injected fuel remained in the liquid phase, which would be expected tomore »« less
