“…The average absolute relative deviations were lower than 2.37%. Gülüm et al [46] developed an artificial neural network (ANN) predictive model for the density of ternary fuel blends (diesel-biodiesel-alcohols (methanol, ethanol, and isopropanol)), which outperformed exponential and linear regression models.…”

This paper reports density, kinematic viscosity, and distillation curves for blends of diesel fuel with n-butanol, diesel fuel with n-pentanol, and diesel fuel with diethylene glycol dimethyl ether. It is known that these properties affect not only fuel transportation and distribution processes but also the phenomena that occur in an internal combustion engine; therefore, these aspects are intriguing to study. Oxygenated compounds such as n-butanol, n-pentanol, and diethylene glycol dimethyl ether can be used as additives for diesel fuel. Their use can contribute to a significant improvement in the fuel’s ignitability due to their high oxygen contents. Measurements of the experimental properties of various blend compositions were carried out at temperatures ranging between 288.15 K and 323.15 K. Based on density and viscosity data, different mathematical models were verified for the purpose of establishing better quality standards for the production of fuel. Good accuracies were obtained in the cases of density, viscosity, and interaction parameters, with the largest average absolute deviation (AAD%) being 0.4351. Moreover, as the determination of density is uncomplicated, rapid, and requires small sample volumes, correlations with the distillation temperatures used for the fuel blends were investigated to estimate the samples’ cetane indices. These determinations will be useful in the automobile industry when designing transport equipment or pipelines in situations when oxygenated compounds may constitute a fuel component in diesel blends.

“…Atmanli et al 41 reported that n‐butanol improved the blending miscibility between diesel and raw cotton oil. In another study, Gulum et al 42 estimated the density of diesel/ waste cooking oil biodiesel/alcohol ternary blends using artificial neural networks and exponential model. They provided a reliable predictive model of density data of diesel/waste cooking oil biodiesel/alcohol ternary blends to facilitate spray and combustion studies of ternary blends.…”

Diesel engines play a vital role in the transportation sector. Ternary blends of alcohol, biodiesel, and diesel have the potential to improve diesel engine combustion and emissions. In the current work, three different types of alcohols; n‐butanol, n‐heptanol, and n‐octanol were added to biodiesel/diesel blends to improve diesel engine performance, combustion, and emissions. The biodiesel was produced from used frying oil (UFO) by ultrasonic enhanced transesterification to achieve the highest yield, lowest viscosity, and minimum production time. Three ternary fuels containing 10 vol% (n‐butanol or n‐heptanol or n‐octanol), 10 vol% UFO biodiesel, and 80 vol% diesel were tested using diesel engine at 25%, 50%, and 75% load conditions. Thermogravimetric analysis of the ternary blends proved the enhancement in the vaporization characteristics compared with biodiesel and diesel fuels; the lighter the alcohol, the faster the vaporization rate but with longer ignition delay which enhanced the premixed burning mode. The specific fuel consumption increased by up to 6% with a slight reduction in thermal efficiency (≈1%) when n‐octanol was used while n‐butanol and n‐heptanol showed comparable values to neat diesel. Ternary blends showed a reduction in smoke opacity, NOx, CO, and CO2 by up to 38%, 11%, 35%, and 14% compared with diesel, while the lowest emissions were attained for the addition of n‐heptanol.
