Abstract

In modern days, transesterified oils are the best suitable alternative fuel for the existing Diesel Engines. Here, to extract the Bio-fuel, animal fat was dried and transesterified with an alkaline catalyst. In this article, the Performance and Emission characteristics of Animal fat Methyl Ester and its blends with diesel oil are analyzed in a direct injection Compression Ignition engine. The experiments were performed on a 4.4 kW, single cylinder, direct injection, air-cooled diesel engine. When compared to diesel, there is a little drop in brake thermal efficiency but a large improvement in carbon monoxide, hydrocarbons, and smoke opacity reduction. The results of the experiment suggest that using 20% of the mix improves performance while reducing emissions. The blends of Animal fat esterified oil (B20) are a good alternative fuel for diesel and could help minimize air pollution since they reduce exhaust emissions while also increasing brake power, brake thermal efficiency, and specific fuel consumption.
