The increasing industrialization of today’S world demands high consumption of petroleum fuels, especially by the agriculture and transport sector. This leads to a rapid depletion of petroleum fuels, which unfortunately have turned out to be non-renewable. The limited availability of petroleum based fuels in certain parts of the world and the environmental pollution caused by them prove to be the two factors for the search of alternative fuels which are preferably renewable. Though the right alternative fuel to replace diesel has not yet been proposed, vegetable oils may be a promising alternate. But the difficulty arises due to their high viscosity which can be overcome to a great extent by the transesterification process. The present paper reviews the use of raw, esterified and blended jatropha oil in diesel engine. The emission characteristics have been evaluated for different proportions of the blends.


Keywords : Transesterification, Micro-emulsification, Bio-diesel, Jatropha oil, Diesel blends.
