Emission and Performance Characteristics of A Diesel Engine Operating on Diesel-Bael (Aegle marmelos) Biodiesel Blends

摘要

The performance, emission and combustion characteristics of a single cylinder direct injection diesel enginefuelled 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 byacid and alkali catalysed reaction due to high acid value of oil. The brake specific fuel consumption washigher for biodiesel due to its lower calorific value. Though BOME and its blends recorded lower brakethermal efficiency, they have lower tail pipe emissions as compared to diesel, except for NOx. Based on thisstudy, bael biodiesel blend B20 (20% biodiesel + 80% diesel, by volume) can be partially substituted fordiesel in existing diesel engines without any modification.
