Abstract: A combustion chamber of a Diesel engine, constructed with cylinder liners, piston, cylinder cover, etc, operates under very serious conditions in high temperature and pressure. Then performances of the engine gradually decrease with operating hours, since various parts constructing the chamber are often worn down through their locomotive motions. Accordingly, we should pay deep attention on well maintenances of the above parts for upkeeping its high efficiential operations. On this purpose, we analyzed scientifically Engine Logs of T/V Kakuyo-Maru of 1044G/T with 2800ps through 12 years of 1975-1987 and could have some results as follows: 1) Cr-galvanization of piston rings greatly contributed to decrease for them to wear-down. 2) Simple regressions between wear-down ratios of cylinders in maximum, α, and operation time in hour of the engine are: athwartship: α=1.6684 exp (-1.1395h) (1/100mm/1000hr) longitudinal: α=1.3517 exp (-1.2075h) (1/100mm/1000hr)
