As the specific gravity of the marine fuel oil increases, catalytic fines of high hardness have come to be seen in the fuel oil in addition to high viscosity and low combustability.<BR>In order to meet these trends, improvements of fuel treatment, startability, combustability, durability, etc. have been taken up as the main study themes these days. Among them the study concerned with the wear has been thought difficult to deal with, in spite of its importance, because of requirements of spending much time for the evaluation, large fluctuation and scarce repeatability among the data. However, as far as no further improvements in the marine fuel characteristics are available in the prospect for the years to come, the study on the wear could not help being taken up among the study themes.<BR>Under the circumstances, it is the writer's eager desire to introduce and offer for the readers' reference, not only improvements of several kinds of methods to know the wear of the cylinder liner and piston rings which are apt to be effected by the fuel oil characteristics, but also a new method developed by us for the purpose.
