Comparative Assessment of Performance, Emission and Combustion Characteristics of Blends of Methyl and Ethyl Ester of Jatropha Oil and Diesel in Compression Ignition Engine
India possesses only 0.3% of world petroleum reserves and hence heavily dependent upon petroleum derived fuels to feed its rapidly growing economy. Diesel Engines due to their superior performance have wide application in India, however, they also pollute environment significantly. Research is underway in India and elsewhere to explore the potential of variety of alternative fuels which could substitute diesel in a holistic manner. And in this context, non-edible vegetable oils are very promising as India has a large area of degraded land where such crops could be raised without compromising food security. Large number of studies have suggested that vegetable oils are not suitable in neat form as a fuel in diesel engine and should be trans-esterified using either methanol or ethanol to form esters to bring their properties similar to diesel fuel.
