In order to analyze a spray characteristics in ultra high pressure region, ultra high pressure injection equipment was developed and the characteristics of free spray injected under atmosphere condition were analyzed. Ultra high pressure over 4,OOObar is realized by 2 stage compression with quick motion using hydraulic system. As injection pressure became higher, spray penetration and spray angle were increased and droplet size was decreased continuously. But the rates of these enhancement become moderate and spray characteristics was constant or reversed.
