Non-edible crops are being grown exclusively for biodiesel production. An alternative approach is to grow a food crop and use the waste material for biodiesel. Crude Jamun Seed Oil (CJSO) is unrefined non-edible vegetable oil, which is available in dry land countries. The research in this area to utilize CJSO as a replacement for mineral diesel is very less. CJSO is obtained from solvent extraction process using n-hexane. The transesterification process for production of Jamun Seed Methyl Ester Oil (JSMEO) has been investigated. The production of high quality JSMEO is obtained from the transesterification with methanol and KOH as a catalyst convertor. Single cylinder four-stroke water-cooled direct injection diesel engine is used in the test rig. JSMEO is used to determine the performance characteristic of the engine. Experiments have been carried out using piston head geometry at constant speed.


Diesel fuels have an important role in the industrial economy of any country. The high energy demand in the industrialized world and widespread use of fossil fuels is leading to fast depletion of fossil fuel resources and environmental degradation. The world petroleum reserves are so unevenly distributed that many regions have to depend on others for their fuel requirements. The degrading air quality due to emissions is the main adverse effect of petroleum-based fuels. All these factors necessitate continued search and sustainable development of renewable energy sources that are environment-friendly. Biomass sources, particularly vegetable oils, have attracted much attention as an alternative energy source. They are renewable and nontoxic and can be produced locally from agriculture and plant resources.
