<div class="section abstract"><div class="htmlview paragraph">Blending of primary alcohol in gasoline surges the vapour pressure significantly and exhibits azeotrope behaviour that effect severely on the atmospheric distillation yields. In this experiment, primary alcohol (Ethanol) were blended in varied volumetric proportion (5%, 10%, 15%, 20%, 25%) with hydrocracked gasoline, influence on volatility behaviour and distillation properties were investigated. Physical properties of this blends were investigated for vapour pressure (VP), VLI, DI and distillation which were selected to evaluate the influence of alcohol in azeotrope behaviour of the fuel mix reflected through pattern of distillation curve (temperature vs % recovery range). This fuel mix exhibited rise in recovery at 70<sup>0</sup>C (E70), VP, VLI and area of azeotrope with increase in % of alcohol volume in gasoline blend. A linear equation is established from the distillation data to predict the impact of % ethanol on % volume recovery and maximum temperature drop in distillation test of gasoline-ethanol fuel blends. Addition of non-ionic surfactant in ethanol blended gasoline (E20) reduces the azeotrope behaviour significantly and flattens the distillation curve. E70, vapour lock index (VLI), driveability index (DI) and area of azeotrope reduces proportionately with the increment of surfactant dosage (%) in E20. This provides a useful information for designing a suitable ethanol blended gasoline fuel, dedicated to spark ignition engine for all weather conditions.</div></div>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
