The present world faces the crisis of fossil fuels as it will no longer sustain in the future, gives a knowledge to look on waste resources, where waste rice and neem seed are utilizable for the production of biofuels by the process of fermentation and transesterification. In this paper, the physiochemical properties of the produced biofuels are examined. The 5% rice wine alcohol is used as an additive with neem methyl ester-diesel blend to lower the viscosity and flash point for the better performance in the single cylinder compression ignition engine. Different blends as D90B5RW5, D85B10RW5, D75B20RW5, and D65B30RW5 are prepared and examined experimentally by varying the engine loads (0-100%) at constant engine speed (1500 rpm). Experimental results showed the reduction of carbon dioxide (CO2), carbon monoxide (CO), hydrocarbon (HC) and smoke opacity, however oxide of nitrogen (NOx) is found higher. In the performance, D75B20RW5 shows 8% higher brake thermal efficiency and 3.33% lower brake specific fuel consumption compared to diesel. While in the combustion the peak cylinder pressure and net heat release rate are seen to be higher for biodiesel blends with additive.
