Experimental Investigation of Mustard Biodiesel Blend Properties, Performance, Exhaust Emission and Noise in an Unmodified Diesel Engine

Mustard biodiesel was produced from waste mustard oil and physicochemical properties were investigated. MB showed superior calorific value (40.404 MJ/kg), oxidation stability (15.92 h), cloud point (5 °C) and pour point (-18 °C) than any other conventional biodiesels. During engine performance test MB10 and MB20 showed 8-13% higher BSFC and 5-6% lower BTE compared to B0. By contrast, MB blends produced 7-8% less BP and 6-8% less engine torque compared to B0. Engine emission and noise test showed 9-12% higher NO, 24-42% lower HC, 19-40% lower CO and 2-7% lower noise emission for MB blends compared to B0. Besides, comparable engine performance and emission characteristics were found for MB10 and MB20 compared to PB10 and PB20 respectively.
