Abstract: This study compared performance and emission characteristics of hybrid fuel blend [diesel-ethanol (anhydrous)-biodiesel (methyl esters of pungamia oil)] with diesel in a multi cylinder, naturally aspirated, direct injection diesel engine. Brake thermal efficiency of engine operated with hybrid fuel blends is found to be slightly higher than that of diesel fuel. Smoke and oxides of nitrogen (NOx) are found to be reduced simultaneously, while using hybrid fuel blends as fuel. Hydrocarbon (HC) emission is higher than diesel fuel for 10% ethanol addition, however when percentage of pungamia methyl ester (PME) increases in blends, HC emission is reduced.Carbon monoxide emission (CO) is found to be higher and a significant reduction is observed whenincreasing percentage of PME in blends.
