“…The parameters, density, SG, and API of the pure COME were 0.89, 0.89 g/cm 3 , and 25.20; meanwhile, the cetane number was 86.40. The parameters of density and SG of the blended fuel the Aq.Et-BD conducted at 7 bar were similar at 0.85 g/cm 3 , which were relatively comparable to previous work [24].…”

The biodiesel blended with aqueous ethanol and diesel was successfully prepared to employ a near isochoric subcritical in which methyl esters were derived from coconut oils. Procedures are as follows: Fermentation of Arenga pinnata sap, a distillation of ethanol using a reflux column, preparation of biodiesel, characterization of biodiesel by GC/MS, blending of aqueous ethanol-biodiesel and aqueous ethanol-dieselbiodiesel, measurement of composition, and analysis of fuel parameters with ASTM standard. The maximum yields of biodiesel obtained were 98.82 % (v/v) and 96.67 % (w/w). The coconut oil methyl esters (COME) degraded from triglycerides were dominated by the short carbon chains, such as C9H18O2, C11H22O2, C13H26O2, C15H30O2, and C17H34O2. It was found that the aqueous ethanol-biodiesel and aqueous ethanol-biodieseldiesel formed an equilibrium line in a triangular graph in specific compositions. The aqueous ethanol concentrations using in the present work were 94-97 %. Components pure ethanol-biodiesel-water, which were in the stable blends, had a

“…When bioethanol is added in binary blends of biodiesel blends, it reduces the ultimate density of ternary blends. The concentration of ethanol in the ternary blends has been linked with the reduction of the density of the final blends [69]. Different concentrations of bioethanol 3%, 6%, 9%, 12%, and 15% by volume were added in binary biodiesel blends, and it was observed that density of ternary blends decreases slightly with increasing concentration of bioethanol.…”

Rapid depletion in fossil fuels, inflation in petroleum prices, and rising energy demand have forced towards alternative transport fuels. Among these alternative fuels, diesel-ethanol and diesel-biodiesel blends gain the most attention due to their quality characteristics and environmentally friendly nature. The viscosity and density of these biodiesel blends are slightly higher than diesel, which is a significant barrier to the commercialization of biodiesel. In this study, the density and viscosity of 30 different ternary biodiesel blends was investigated at 15 °С and 40 °С, respectively. Different density and viscosity models were developed and tested on biodiesel blends soured from different feedstock’s including palm, coconut, soybean, mustard, and calophyllum oils. The prognostic ability and precisions of these developed models was assessed statistically using Absolute Percentage Error (APE) and Mean Absolute Percentage Error (MAPE). The MAPE of 0.045% and 0.085% for density model and 1.85%, 1.41%, 3.48% and 2.27%, 1.85%, 3.50% for viscosity models were obtained on % volume and % mass basis. These developed correlations are useful for ternary biodiesel blends where alcohols are the part of biodiesel blends. The modeled values of densities and viscosities of ternary blends were significantly comparable with the measured densities and viscosities, which are feasible to avoid the harm of vehicles’ operability.

In the last few years, increasing concern about the harmful effects of the use of fossil fuels in internal combustion engines has been observed. In addition, the limited availability of crude oil has driven the interest in alternative fuels, especially biofuels. In the context of spark ignition engines, bioalcohols are of great interest owing to their similarities and blend capacities with gasoline. Methanol and ethanol have been widely used, mainly due to their knocking resistance. Another alcohol of great interest is butanol, thanks to its potential of being produced as biofuel and its heat value closer to gasoline. In this study, a comparative study of gasoline–alcohol blend combustion, with up to 20% volume, with neat gasoline has been carried out. A single-cylinder, variable compression ratio, Cooperative Fuel Research-type spark ignition engine has been employed. The comparison is made in terms of fuel conversion efficiency and flame development angle. Relevant information related to the impact in the combustion process of the use of the three main alcohols used in blends with gasoline has been obtained.
