Now a days the world is confronting with twin crises such as energy demand and pollution. The economic growth of any county is related with energy demand. IC Engines are the major energy consumers to eradicate the problem alternative fuels are one major source to replace diesel fuel partially or fully. The availability of conservative fuels decreased continuously, these reasons makes to find the alternative fuels especially biofuels. The use of biodiesel considerably reduced emission and increase the performance of the engine. Now a days researchers have reported the possibility for the production of biodiesel from non edible oil jatropha curcus, pongamia pinnata etc. In the present years, population of vehicles increased enormously which increases the demand of fossil fuel, There is a best source of raw material that is calophyllum inophyllum oil for biodiesel production. In present study calophyllum inophyllum is used as fuel in C.I engine. Blends such as CIME10, CIME20, CIME30, CIME40 are taken for the experimentation. The optimized blend is identified as CIME20 while compared the test results with the baseline readings of diesel fuel. The optimized blend is further tested with Zinc Oxide nanoparticles as fuel additive with various concentrations of 25ppm, 50ppm and 75ppm. Brake thermal efficiency is increased by 3.48 % and Brake specific fuel consumption is reduced by 7.12% and emission of CO and Unburnt Hydro carbons are reduced where as NOX results are moderate.
