Bio-diesel has similar properties with diesel as the alternative fuel and is more favorable form environmental issues. In this pater, we were performed a study on the atomization characteristics of bio-diesel. we used the beef-tallow and lard of animal fats BD and palm of vegetable BD As experimental fuels and performed different injection pressure varied form 25MPa to 160MPa by experiments conditions. by using high speed digital camera, we were analysed for macroscopic characteristics of spray, such as spray angle , spray penetration and spray velocity, on injection duration at 1.5ms. Also, When using LDPA device, we were known about the microscopic characteristics of spray, such as SMD and D<SUB>max</SUB>, on injection duration 4ms. As the experimental results, The spray penetration increased with increasing injection pressure. Beef-tallow BD was shown adjacent to diesel. The spray angle showed almost similar distributions regardless of BDs and injection pressure. also, The mean droplet size such as SMD and D<SUB>max</SUB> of BDs decreased with increasing injection pressure. In the case of injection pressure of 25MPa, D<SUB>max</SUB> showed that about BDs in the size fo the difference was caused significantly.
