Abstract

Diminishing fossil fuel reserves and environmental concerns have stimulated research into biofuels as potential renewable and sustainable replacements for fossil diesel. The present research aimed to investigate the feasibility of using mustard biodiesel blends for energy generation in order to reduce air and noise pollution. Mustard biodiesel (MB) was produced from waste mustard oil and the physicochemical properties were investigated. MB showed a superior calorific value (40.40 MJ/kg), oxidation stability (16 h), cloud point (5 °C) and pour point (-18 °C) than any other conventional biodiesel. During engine performance tests, 10% and 20% MB blends showed 8-13% higher brake specific fuel consumption and 7-8% less brake power compared to diesel fuel. Engine emissions and noise tests showed 9-12% higher NO, 24-42% lower HC, 19-40% lower CO and 2-7% lower noise emission for MB blends compared to diesel fuel. Additionally, comparable engine performance and emission characteristics were found for 10% and 20% MB blends compared to same percentages of palm biodiesels, respectively. In conclusion, 10% and 20% MB blends can be used in diesel engines without modifications.
