舶用ディーゼル機関から排出されるPMの分析事例-大気質シミュレーションへの適用

抄録

This work is designed to collect components of particulate matter (PM) emitted from two medium speed 4-stroke marine diesel engines and a low speed 2-stroke marine diesel engine and to use these emissions as an inventory of air pollutants for air quality simulation. The sulfur content of the fuels used in the experiment ranged from 0.071% to 2.49%. The PM sample was examined with two partial flow dilution systems in accordance with JIS B 8008-1: 2000. The components of nitrate and sulfate in PM were analyzed by ion chromatography. The components of organic carbon and elemental carbon in PM were analyzed by the thermal-optical reflectance method (protocol: IMPROVE). The results were examined in terms of component (five classifications - nitrate, sulfate, organic carbon, elemental carbon and others) and points to note for the creation of the inventory were prepared.
