The Wide Fuel and its Characteristics

Water in diesel emulsion is an optional fuel, has a potential to reduce the formation of both nitrogen oxides, carbon dioxides and particulate matters in diesel engine. Thus the performance of this emulsified fuel strongly depends on the type of emulsion, stability of emulsion, amount of surfactant and the physio-chemical properties. In this study, water in diesel emulsion fuels of 5%, 10%, 20%, 25% water by volume was prepared by a mechanical stirrer. Physical and chemical properties of emulsion were examined as this properties could influence the spray characteristic of the emulsion which can affect the ignition delay and flame propagation, the carbon contents for emulsified fuel with 10% and 20% were low droplet size of the emulsion was found to be less than 2 µm. The water content in the emulsified fuel also include the amount of surfactant density and viscosity was found to be higher for all of the water in diesel emulsion the pure diesel.
