A Study for the Control of Lubricating Oil on Marine Diesel Generator

Abstract

In recent years, the "control" of lubricating oil in diesel ships becomes an important matter for engineers by the use of C fuel. The properties of lube oil have a great influence on the maintenance of the supercharged diesel generators, The following are the essentials grasped by a few years survey on the control of lube oil. Unlike for the land engines, the condition of consumption for marine diesel generators plays an important role in the balance of lube oil consumption in the ships. The consumption of main engine oil and regenerated wast oil of diesel generator increases with the lapse of time of engine operation. Accordingly the decision of oil change time is of importance for oil control. Its interval should be determined considering the next four items. (1) Engine maintenance and prevention of damage. (2) Interval of engine overhaul. (3) Lube oil consumption in ship. (4) Lube oil properties. Because of the advance of high powered engine and severe demand for lube oil, oil flushing and use of heavy duty oil will become problems for oil control in future.
