Alternative fuels such as butane and DME have different properties including high vapor pressure, low viscosity, and low surface tension, compared to other conventional fuels. These properties may lead to different atomization characteristics such as liquid core breakup, droplet size distribution, and evaporation process. To investigate these effects, a method based on shadowgraph technique to take spray images for droplets and surrounding gas was tested and evaluated. Experiments were performed at low injection pressure for early stage direct injection. It could be concluded from the results that the proposed method could be used to investigate the structure of evaporating spray, and the vapor layer around the spray core could be correlated to the turbulent mixing length for both of butane and DME sprays by observing vapor and spray core.
