Abstract

In this study, yellow oleander biodiesel was produced using a synthesized eggshell-derived nanocatalyst. Biodiesel fuel properties have been evaluated against a number of ASTM standards. A test was conducted in which an engine was fueled with petroleum diesel and four different petroleum diesel/biodiesel blends (B5, B15, B20, B30, and B100) at five different loads (0, 25, 50, 75, and 100 %) were analyzed in a single-cylinder internal combustion engine. Summaries of observations made from this work are reported. The lower calorific value decreased as the blend ratio increased and B100 had the lowest CV. Compared to petroleum diesel fuel, oleander yellow biodiesel had higher BTE, BSFC, and BP. The use of biodiesel resulted in lower emissions of CO and increased emissions of CO2 and NOx compared to petroleum diesel. This study showed that tailpipe emissions from diesel/biodiesel blends were lower than those from diesel fuels.
