Abstract: Ships are a major source of air pollution, which significantly impacts global health. In this study, the gaseous and particulate emissions from the main engine, auxiliary engine, and auxiliary boiler of a modern Tier Ⅲ large ocean-going vessel fueled with marine gas oil and heavy fuel oil have been investigated. Emissions of gaseous pollutants in the exhaust were measured online and particulate samples were collected to determine detailed physical and chemical properties. The results indicated that CO2 and NOx are the main gaseous pollutants, while organic carbon accounts for the majority of particulate pollutants for the three devices. The element carbon emissions of the auxiliary engine decreased with load increasing while those of the main engine maintained a level of approximately 0.062 g/kWh. The black carbon emissions of the main and auxiliary engine resulting from using marine gas oil were higher than heavy fuel oil. Consistent correlations among pollutants were observed for the engines. Finally, the measured value of element carbon cannot be utilized as a substitute for black carbon emissions due to the presence of light-absorbing organic carbon in organic carbon.
