The electrospray is an injection system which is using the high electric potential to cause the liquid atomization without traditional pressure force. This investigation reports the difference of electrode distances between the capillary and wire-netting effect on electrostatic atomization from bio-emulsified fuel. The well-known biofuel, such as biodiesel fuel (BDF), which is expected as carbon neutral fuel and contained water remained in the production phase, thus, making the biodiesel as emulsified fuel can take advantage of water fractions to provide low temperature condition (LTC) and result in the reduction of nitrogen oxide (NOx) emission. In addition, the viscosity of emulsified fuel is depending on the class of surface-active agent, nevertheless the emulsified fuel has the large electric conductivity which can be used in electric potential supplied to control and atomize into several particles. In this paper, the breakup and atomization process of bio-emulsified fuel was investigated with the different electrode distances to estimate the effects of electric field. The atomization mode and injection angle is reported in deal. Furthermore, as the electric field distribustion is estimated with the droplet movement and effect of electric field on the atomization mode is dicussed in this paper.
