The CO and HC are not difficult to meet, but the standard of NOx is a great challenge. This paper used gasoline/water emulsions with 5, 10, and 15% water for a four strokes, 125cc motorcycle engine to reduce NOx emission. The experimental results indicated that emulsified fuel with appropriate rate of water can increase engine torque and reduce fuel consumption. The exhaust emissions of NOx and CO were significantly reduced. When use gasoline/water emulsions with 10% water, Engine torque increase 5.02%, CO decrease 35.2%, NOx decrease 30.6%, but the HC emissions was increased. The emulsified fuel with 15% water is the worst case due to too much water in the fuel. The exhaust temperature is increased and the engine torque is decreased due to slow combustion rate.
