“…However, the hydrous ethanol blend produced higher HC emissions than the anhydrous ethanol gasoline blend. The values were still lower than those for gasoline . Neat hydrous ethanol (ethanol with 6.8% of water by volume) is reported to produce higher thermal efficiency than a blend of anhydrous ethanol and gasoline (E22) in a port fuel‐injected SI engine at all speeds due to advanced spark timings and higher flame velocity.…”

“…It was observed that a carbureted engine operated with 23.3% by volume of hydrous ethanol gasoline blend (hydrous ethanol that contained 6% by volume of water) produced lower power output and thermal efficiency than gasoline and anhydrous ethanol blend (99.5% purity of ethanol with gasoline). This was due to lower energy density of the blends since the fuel flow rate was controlled by the carburetor which was tuned for gasoline operation . Low in‐cylinder gas temperature with blends led to lower NOx emission and exhaust gas temperatures than gasoline.…”

SUMMARY Performance, emissions and combustion characteristics of a port‐injected engine fuelled with hydrous ethanol gasoline blend (E10 ‐ 10% of hydrous ethanol by volume in gasoline) were compared with gasoline operation. Hydrous ethanol blend produced higher power output with lean mixtures at part throttle condition. Higher flame velocity and wider flammability limits of the blend resulted in lower cycle‐by‐cycle variations in indicated mean effective pressure as compared to gasoline. Hydro carbon emission was also lower due to the oxygen available in the fuel (E10), which enhanced the combustion rate. Higher latent heat of evaporation of the ethanol blend and water present in it resulted in lower in‐cylinder temperature, which in turn led to lesser NOx emissions. Thermal efficiency with the blend was higher in the leaner operating conditions than gasoline. Not much difference in performance, emission and combustion characteristics between neat gasoline and E10 were observed at full throttle operation. On the whole, hydrous ethanol blends can be used as a fuel with good performance and low emissions at part load condition. Copyright © 2012 John Wiley & Sons, Ltd.

“…Alcohols burn with a faster flame speed than gasoline, and they do not contain additional elements such as sulphur and phosphorus. Rajan and Saniee (1983) investigated the characteristics of hydrated ethanol with gasoline as a means of reducing the cost of ethanol/gasoline blends for use as a spark ignition engine fuel. Engine experiments indicate that, at normal ambient temperatures, a water/ethanol/gasoline blend containing up to 6 vol% of water in the ethanol constitutes a desirable motor fuel with power characteristics similar to those of the base gasoline.…”

BACKGROUND: The purpose of this study was to evaluate the juice of the fescue grain sorghum, since it is a low-cost agricultural waste, for the production of bioethanol to be used as a gasoline additive. In addition, the octane number has been investigated by varying the ethanol-gasoline mixture 2, 6 and 10%. RESULTS:The wort fermentation was carried out with commercial bread yeast (Saccharomyces cerevisiae). The liquor obtained was characterized and quantified through gas chromatography. Bioethanol-gasoline mixtures were prepared as: 2, 6 and 10% v/v to determine their octane index. Bioethanol was purified in a fractional distillation tower, attaining thereby a 93.5% purity: lastly, it was dehydrated through molecular sieves to obtain a 99.2% final purity bioethanol. Spectroscopy aided also to determine that the bioethanol-gasoline mixture containing 10% ethanol attained an octane index of 89, which is the value required for commercial gasoline in Mexico. CONCLUSION:The bioethanol obtained from the fermentation of juice of fescue grain sorghum is indeed viable to be used as additive in gasolines. The fermentation can be carried out with the bread yeast, at the natural pH of the juice and without the addition of nutrients, which leads to an attractive economic process.
