Performance, emission characteristics of CI engines fueled with Annona seed biodiesel blends and 1-pentanol as an additive

Abstract

Fossil fuel is one of the predominant sources for automobiles are facing depletion across the world. This depletion put up a greater demand for the need of alternative fuel sources for automobiles. As a solution for this issue, many researchers formulated and synthesized biodiesel from the oil extract of plant seeds and bio waste materials. The present work involves the synthesis and extraction of methyl ester from the oils of Annona seed and blended with diesel along with 1-Pentanol as an additive. Three-blend mixture of biodiesel is prepared with methyl ester of 10%, 20%, and 30% of Annona seed oil with 10 ml of 1-Pentanol in it. The formulated biodiesel is evaluated for its performance using the Kirloskar Diesel engine under different loading conditions. The evaluation is carried out in terms of brake thermal efficiency, brake specific fuel consumption, and other parameters along with emission characteristic analysis of CO, NOx, and CO2, From the observed results, the biodiesel blend with 30% of Annona seed methyl ester showed better performance. However, the emission analysis over different gases showed biodiesel with 10% of Annona seed methyl ester showed reduced emission.
