As the energy consumption increases day by day and also due to the scarcity of conventional fuels, the crude oil price was going up day to day and there will be no more conventional fuels in future and also increasing the environmental pollution by the usage of crude oils there is a need for the search of alternative fuel sources for the automobile applications. There are many alternate fuels we already existing like bio-diesel, bio-mass, alcoholic fuels, hydrogen, non-fossil methane and non-fossil gases (like LPG, CNG) and other bio-mass sources which were useful for different applications, out of these bio-diesels are one of the prominent alternative fuel for diesel engines. Therefore in the present investigation the oil taken is the neem oil which was obtained by the neem plants. After finding the optimum blend in the third stage the test to be conducted again on the engine to find out the performance and emission parameters by adding nano powder to the optimum blend. The main purpose of adding the nano powder is to know ignition and brake thermal efficiency along with emission parameters. Finally the performance parameters and emission parameters obtained by the above tests are compared with the optimum blend
