Abstract The higher alcohol such as hexanol was added at various concentrations with diesel in this current research work while retaining the neem biodiesel at 20% concentration to form the ternary fuel blend. In a single cylinder diesel engine, three distinct ternary blends (B20HB10, B20HB20, B20HB30) were taken and all the blends were tested and the results were contrasted with a binary blend (D80:B20, namely B20) and pure diesel fuel. The experiment showed that when the alcohol concentration rises from 10 % to 30 % because of the decrease in calorific value, the brake thermal efficiency decreases slightly. In addition, owing to the availability of intrinsic oxygen in it, all the ternary blend contributes to a decrease in HC and CO emissions, which leads to more complete combustion. It was also found that there was a substantial reduction in NOx emissions for all ternary blend due to the high latent heat of vaporization.
