The performance, emission and combustion characteristics of a single cylinder direct injection diesel engine fuelled with bael (Aegle marmelos) seed oil methyl ester (BOME), diesel and their blends (B20, B40, B60, B80 and B100) have been presented in this paper. BOME was prepared from bael seed oil with methanol by acid and alkali catalysed reaction due to high acid value of oil. The brake specific fuel consumption was higher for biodiesel due to its lower calorific value. Though BOME and its blends recorded lower brake thermal efficiency, they have lower tail pipe emissions as compared to diesel, except for NOx. Based on this study, bael biodiesel blend B20 (20% biodiesel + 80% diesel, by volume) can be partially substituted for diesel in existing diesel engines without any modification.

Abstract


The performance, emission and combustion characteristics of a single cylinder direct injection diesel engine fuelled with bael (Aegle marmelos) seed oil methyl ester (BOME), diesel and their blends (B20, B40, B60, B80 and B100) have been presented in this paper. BOME was prepared from bael seed oil with methanol by acid and alkali catalysed reaction due to high acid value of oil. The brake specific fuel consumption was higher for biodiesel due to its lower calorific value. Though BOME and its blends recorded lower brake thermal efficiency, they have lower tail pipe emissions as compared to diesel, except for NOx. Based on this study, bael biodiesel blend B20 (20% biodiesel + 80% diesel, by volume) can be partially substituted for diesel in existing diesel engines without any modification.
