N2 - This paper describes the application of a i.e. fuel-water-fuel injection system for diesel engines. This system makes it possible to inject water during fuel injection from the same nozzle hole without mixing the liquids. First, it was confirmed that NOx reduction and improvement of thermal efficiency and smoke density could be achieved using this system. The reason for such improvement of combustion with water was investigated in detail using a special test engine with which burning flames could be visualized by taking high-speed photos. Moreover, the distribution of the water vapor in the fuel spray was estimated through calculations using the `KIVA' code. Using these studies, this system may soon be put to practical use.
