Greater part of Japanese domestic commercial ships install Low-speed, four-stroke trunk piston type engines as their primemovers enjoying its merits in fuel economy and maintenance cost.<BR>Marine engines have been improved restlessly to be less fuel consumption, higher output, and availability of low quality fuels especially since world oil crisis.<BR>Fuels supplied to ships recently have mainly been manufactured in catalysis process plant or distilled residues thined down by visbreaker-refined light oil because oil suppliers make their process fit to increasing market demands of lighter oils.<BR>Fuels manufactured by these process have negative properties such as low ignition quality, long combustion period and low thermal stability that cause troubles in engines and auxiliary machineries.<BR>Considering that there is close relationship between contamination of system oil and bad combustion inside engine, we studied system oil contamination and fuel quality comprehensively.<BR>As a result of this study, we have establishied a guideline with which engineers are able to judge whether system oil contamination has been caused by bad combustion of engine or other reasons.
