Abstract：  In this paper， whereby the marine diesel engines are faced with the various complex operating conditions in the course of vessel operation， the causes and hazards of carbon deposition built up in the diesel engines are further analyzed. By means of selecting the cylinder lubricating oil type， and setting the cylinder oil injection rate and the requirements of operation， the corresponding countermeasures are thereby proposed.

Key words： marine diesel engine; cylinder lube oil; carbon deposition

1     前言

隨著船東對(duì)船用低速柴油機(jī)功率重量比、燃料經(jīng)濟(jì)性、排放等要求不斷提高，柴油機(jī)的平均有效壓力、爆壓等關(guān)鍵參數(shù)也隨之提高。（剩余3994字）
