The new fuel injection method, which is using the high voltage electrical discharge, is proposed. The long penetration depth and the rapid diffusion will be available due to short duration electrical discharge. The purpose of this study is to clarify the influence of injector configuration on the fuel spray condition. The liquid fuel filled up the cavity of injector and was spread into the combustion chamber filled with the air. The fuel spray process was visualized by a schlieren system. In cases of small orifice diameter, the injector which has cavity 5^*5 can inject fuel jet very fast as compared with other cavities. In cases of large orifice diameter, for all cavities, the fuel is widely spread from the injector. Therefore, the fuel jet velocity and the spray angle are influenced by cavity volume and orifice diameter. The injector with large orifice diameter is suitable for the fuel injection system of diesel engine.
