In order to improve evaporation rate of fuel droplets in the combustion chamber such as diesel engine, it has been proposed to use a porous plate on the surface of a piston. The aim of this study is to understand the effects of porous characteristic on the fuel droplet evaporation phenomena. The fuel droplet after contacting with the hot porous plate were observed using high speed camera, and life time of the droplet and transient temperature of the porous surface were measured. It was found that the thermal conductivity and the pore diameter of the porous plate play important roles in the evaporation phenomena.
