Emulsified Biodiesel has lower NOx and Smoke emissions compared with Biodiesel. In this study, a new emulsified Biodiesel with 15 wt% water is made without adding any emulsifier, and the combustion characteristics and exhaust emissions for the new fuel are investigated using a DI diesel engine. The new fuel has shorter ignition delay and lower CO, HC, Smoke and Aclorein emissions compared with the 15 wt% water emulsified Biodiesel with adding 0.1 wt% crude glycerin as an emulsifier. Moreover,

The emulsified Biodiesel has larger water droplet size and lower viscosity with decreasing crude glycerin content, and as the result, the ignition delay becomes shorter, and the HC, CO, Smoke and Aclorein emissions become lower.
