Abstract

The deterioration of fossil fuel reserves, increased consumption of diesel fuel in automotives and perilous impact environmental pollution caused to find a economically renewable available and eco-friendly biofuel to replace the fossil diesel fuel. Recently, the past research reviews revealed that biodiesel that was prepared from vegetable oil (edible and non-edible) and or animal fats as one of the substitutes of fossil diesel fuel. But the tested diesel engine is not delivering adequate brake power as needed to perform the designated work. For this reason, the present paper is aimed to find the optimized combine engine parameters combination to enhance the engine power of a single cylinder, DI diesel engine using Taguchi method when fueled with Azadirachta indica oil methyl ester (AIOME) and its diesel blends. The research also investigates the effect of fuel injection pressure, AIOME percentage in blend and engine load which were considered as the controlled factors on engine performance characteristics in terms of brake thermal efficiency (BTE) and brake specific energy consumption (BSFC) which were considered as the response variables. The Taguchi’s L16 orthogonal array was generated using design of experiments (DoE) methodology and a series of experimental tests were conducted as per designed array with different combination of influencing factors. Taguchi method employed to evaluate the influencing factors and significance of impact on response variables. The Taguchi analysis revealed that that the B20A blend of AIOME at 75% of engine load with 230 bar of fuel injection pressure were optimum parametric combination setting to enhance the BTE and BSFC to the highest possible level and to reduce the BSFC. Engine’s performance characteristics are mainly influenced by engine load, followed by percentage of AIOME in blend and is least influenced by injection pressure.
