Abstract
Marine diesel fuel oil will be more widely used for marine diesel engines in the future because its low sulphur content helps in meeting regulations concerning exhaust gas emissions. Even if the properties of marine diesel fuel oil remain within those specifications, however, cases have been reported of poor combustion in marine diesel engines for generators.
This paper reports the relationship between combustion characteristics and carbonaceous bonds as well as the possibility of evaluating combustion characteristics by identifying carbonaceous bonds in fuel oil.
