An analysis of cause and effect relations in diagnostic relations of marine Diesel engine turbochargers

The article justifies the need to analyse diagnostic relations for turbocharger operation purposes. Types of turbochargers most frequently used in modern marine engines have been presented. Turbocharger decomposition has been conducted on a selected example. The influence of typical inefficiencies in respect to symptom value changes has been worked out for each heat engine and sub-system. Validation of selected cause and effect relations has been based on operational experience in the technical scale.
