Abstract: In this experimental study, the performance of the diesel engine was analyzed for biodiesel derived from Calophyllum inophyllum . The impact of the addition of additives such as N- octanol and N- butanol with Calophyllum inophyllum biodiesel has been assessed. Impact of the application of hybrid N- octanol and N- butanol with biodiesel on emission profile used for the engine performance has also been demonstrated. Response surface analysis of alcohol additives-biodiesel blend was performed separately in this study for the engine efficiency and emission profile. A combination of N- octanol and N- butanol presented the highest brake thermal efficiency (BTE) and lowest carbon monoxide (CO) emission among the ternary blends of octanol. N- butanol-biodiesel blend presented the lowest hydrocarbon (HC) emission among the blends of N- butanol. N- octanol with 5 and 10% addition with biodiesel showed the lowest HC emissions among the blends of octanol. The response surface methodology (RSM) optimization revealed that the optimized thermal efficiency and emission were obtained at full load and minimum load, respectively. The addition of N- octanol hindered the emission at all loads, while N- butanol reduced it at higher loads. A strong correlation between the load and alcohol additives on the engine performance and emission profile has been obtained using the RSM optimization approach. The R-squared value obtained from the RSM was 0.92 and emission profile has been characterized.
