Abstract
In recent years, the quality of marine residual fuel oil has been deteriorating due to the escalating prices of crude oil and the sophistication of oil refining technologies. In this regard, the deterioration of combustibility causes problems such as poor combustion in diesel engines, which can result in major failures. In the present paper, we summarize the characteristics and trends regarding the ignitability and combustibility of marine residual fuel oil, as well as the analysis results of their relation to case studies of combustion troubles encountered.Furthermore, upon applying the Mahalanobis-Taguchi system to the establishment of a practical method for evaluating the quality of marine residual fuel oil, it was found that trouble inducible oil can be easily identified, indicating that it is an effective analytical method.
