The authors investigated the influence of injection characteristics on the performance of a direct injection diesel engine driven by water to gas oil emulsified fuel. Before the engine experiments, this paper describes the experimental results of spray characteristics such as spray configuration, spray penetration, spray angle and drop size distribution with gas oil and emulsified fuel. The experiments were carried out under room temperature and at atmospheric pressure conditions with a conventional diesel engine injection system. The results showed that in the emulsified fuel spray the atmization characteristics were poorer and Sauter mean diameter was larger in comparison with the gas oil spray, because the emulsified fuel has high kinematic viscosity. It was also indicated that the dispersion of emulsified fuel spray deteriorates due to the decreasing spray angle and the increasing fuel spray density at the central portion.
