Spray characteristics of diesel fuel injection is one of the most important factors in diesel combustion and pollutant emissions especially in HSDI (High Speed Direct Injection) diesel engines where the interval between the onset of combustion and the evaporation of atomized fuel is relatively short. An investigation into various spray characteristics from different holes of VCO(Valve Covered Orifice) nozzles was performed. The investigation manifestly reveals the different spray patterns at the beginning of injection produced by VCO nozzle equipped with 2-spring injector can be identified as three distinct type with there own macroscopic and microscopic characteristics, while macroscopic non-uniformity disappears at 0.9~1.0ms from the start of injection
