Environmental concern has promoted marine industry to undertake research and develop engines with low emissions and high efficiency. This study aims to investigate the effect of water on exhaust emissions, engine performance, fuel efficiency and combustion characteristics. The experiment was conducted with induction of water into the intake air manifold. Water addition is found very effective in reducing NOx emissions without deteriorating engine efficiency. As a result, the compromising relationship between NOx and SFOC is slightly improved at moderate W/F ratios. NOx is reduced by up to 40 % with water addition while CO emission seems to decrease only at high power. Furthermore water addition tends to increase the concentration Of C02 in the exhaust gas and to decrease the percentage of excess oxygen. Apart from emissions, engine performance was closely monitored during the tests. The results suggest that the use of water is a viable method, which could lead to practical development in the future.
