This document brings together insights into mechanisms and phenomena of oil degradation resulting from stress of the lubricant in large 4-stroke (medium speed and high speed) and 2-stroke diesel engines. Its objective is to contribute to the understanding of the complex processes resulting in oil degradation and thereby, to a degree, enable control of them so that the engines, their treatment systems and the lubricant itself remain in an acceptable condition for an acceptable period.
The intended readership of this document are all people related to large engines in marine propulsion, land based power-generation and railroad industry - for example users and producers of equipment, students and newcomers to the industry etc.
This publication is for guidance and gives an overview regarding the lubrication of two-stroke crosshead diesel engines.
