In this present work, experiment has been conducted in phases I, II categories. In phase I, 50D: 50E (50 Diesel: 50 Ethanol - 100% Proof), 60D: 40E and 70D: 30E have been prepared under water - in - oil type emulsion preparation method and the results have been compared with neat diesel fuel. After identifying the best fuel ratio, it passes to phase - II. In phase - II, the selected fuel has been sprayed in to different fuel injection nozzles of 18°, 20°, 23° and 24°. After that the performance and emission tests have been carried out. The out come result shows better performance and less emission have been given by the fuel 50D: 50E at 24°. Further the ignition delay, the maximum heat release and peak combustion pressure tests are conducted. Also P - θ diagram is drawn between crank angle Vs cylinder pressure. The maximum value is attained by the emulsified fuel ratio 50D: 50E at 24° fuel injection angle. All the tests have been conducted by maintaining the engine speed at 1500 rev/min. The result shows that 50D: 50E emulsified fuel has been identified as a good emulsified fuel and its better operation is obtained at 24° fuel injection spray angle based on its best performance and less emissions.
