연료의 성분에 따른 디젤엔진의 Emission 특성에 관한 연구

Sulphur Oxides(SOx), Nitrogen Oxides(NOx), Carbon Dioxides (CO₂) and particulate matters(PM) are the main air pollutants emitted from ships. The NOx emission has been regulated by the 2000 NOx Technical Code and maybe further reinforced from its present level in 2008. Moreover, the fishing industry is equally faced by the increasing cost of fuel oils nowadays. Thus, it is a necessity for this industry to explore on some alternative fuels and, at the same time, comply with the different emission regulations. For this study, an experiment was conducted on a test vessel (fishery survey vessel) with the main engine and generator engine operated on expensive marine gas oil (MGO). During the experiment, two pre-refinery systems were installed and different fuel oil samples were employed for the MIE and the G/E. Other verified items include the NOx emission, soot concentration, mean effective pressure, and exhaust gas temperatures. The results confirmed the compatibility of some fuel oil types with the engines and meet the emission standards without having adverse effect on the mean effective pressure.
