Abstract : The transport requirement in India is enormously increasing, which stimulates the energy utilization by 4.1–6.1% rise every year from 2010 to 2050. Additionally, the number of private vehicles keeps on increasing every year and consumes more fuel which makes India the third largest foreign buyer of crude oil in the world. Owing to this issue, the promotion of alternative fuels (biodiesel) which are from different feedstocks for transportation is necessary. These biodiesels hold enhanced emission characteristics compared with neat diesel, therefore the biodiesel can be considered as a substitute for diesel and if blended with diesel, it gives enhanced performance characteristics. Tests on the performance of the engine were carried out at different numbers of holes, different weight percentages of blends, and different loads. The objective of this work is to identify the optimal process parameter, which minimizes the Brake-Specific Energy Consumption (BSEC) and maximizes the Brake Thermal Efficiency (BTE). The experiments were designed based on the RSM Design of experiments. Using the RSM desirability function, the process parameters are optimized for better performance. The influence of process parameters on responses is investigated using ANOVA. The blending ratio has the maximum percentage contribution of 44% for BSEC and the number of holes has the maximum percentage contribution of 39.85% for BTE. The optimal parameters of four holes in the fuel injector, 40% of biodiesel with 60% of diesel, and 100% of load are identified.
