Effect of ternary fuel blends on performance and emission characteristics of single cylinder diesel engine

Abstract

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.
