In order to know the basic data of DME spray characteristics, the effect of injection pressure and injection nozzle diameter on the injection rate, spray angle and spray tip penetration distance and spray volume are examined. The former is measured by the use of Bosch injection rate measuring system, and later are analyzed by the use of constant volume vessel and schlieren method. Constant volume vessel was controlled by nitrogen gas. Result from spray visualization experiment, DME spray volume decreases, when the ambient pressure is heightened. It is cause decrease the specific volume by the ambient pressure increased. And, the effect of nozzle diameter and injection pressure to the spray angle decreases, when the ambient pressure is heightened.
