Abstract

Determination of the analytical relationship between real time changes in the quality characteristics of motor oils and an assessment of the state of the mechanism units subjected to friction is important when predicting the tribological characteristics of marine diesel engines. Changes in the lubricant parameters reflect the current technical condition of the engine components and assemblies. A method of process parameter matrix (PPM) is proposed to control the wear dynamics of a marine diesel engine. PPM is used to process statistical data on the performance of oils used in a MAN B&W Diesel Den 6L28/32A marine diesel engine through 2007 to 2021. The results of practical studies of changes in the physicochemical characteristics of motor oils in real operating conditions are presented. The results obtained can be used in the development of specialized software that allows obtaining operational information about the dynamics of engine wear.
