摘要：Emulsification technique is one of the most important methods to the reduction of pollutants from dieselengine. In this research, a single cylinder diesel engine was operated with water in canola biodieselas fuel and the effect of water emulsification on the engine performance and emissions wereinvestigated. Emulsified biodiesel fuels of 3.5 and 10 water/water-biodiesel mixture fuel ratios byvolume were used in a light-duty diesel engine, operating at various engine speeds. The results showthat the brake engine torque, the brake engine power and the brake thermal efficiency decrease as thewater percentage in the emulsion increases but the brake specific fuel consumption (BSFC) increasesas the percentage of water increases in the emulsion fuel. In addition, carbon monoxide (CO) andhydrocarbons (HC) increase as the percentage of the water increases in the emulsion fuel. However,exhaust gas temperature, nitrogen oxides (NOx) and smoke emissions decrease as the percentage ofwater increases in the emulsion fuel.
