Performance and emission studies of ternary fuel blends of diesel, biodiesel and octanol

Diesel engines are very popular prime movers, however, they are also a major producer of environmental pollution. Ternary fuel blends of diesel, biodiesel, and octanol can be a suitable solution to the problem. In the present work, different ternary fuel blends were formulated and used in a diesel engine. Brake thermal efficiency and brake specific energy consumption of the blend containing 10% octanol, 10% biodiesel, and 80% diesel were found better than diesel owing to more oxygen content and comparable properties. Moreover, lower emissions (carbon monoxide, unburnt hydrocarbon, nitrogen oxide, and smoke opacity) and better combustion of the blends was observed.
