Air pollution near harbors and inland seas is going to be an urgent problem for marine plants.
In this paper, some elemental experiments for exhaust emission controls of marine diesel engines are discussed, such as;
1. Techniques of NOx measurements in the case of high water concentration.
2. Exhaust emission characteristics affected by injection timing, exhaust valve timing, and inlet air temperature.
3. Effects of fuel-water emulsion introduced into the combustion chamber.
