• It was reported that the emulsified fuel improved the thermal efficiency and suppressed the formation of thermal NO, soot particles (carbon components etc) in diesel engine due to the secondary atomization caused by the micro-explosion. But the micro-explosion phenomena and the behavior of water particles in the emulsified fuel droplet are not clear enough to understand its effects on combustion. Thus, this paper introduces the experimental study on combustion of single droplet of water-in-fuel emulsions of marine diesel fuel (MDF) in high temperature and high-pressure chamber. The experimental results show that, in atmospheric experiment, as the mean diameter of the water particles is increased, the micro-explosion becomes violent, the droplet's burning time and the ignition delay becomes shorter; on the other hand, in high pressure experiment, as the initial pressure of the chamber is increased, the projected flame area becomes smaller the micro-explosion becomes weaker.
