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
