Design and Implementation of Integrated Monitoring and Diagnosis System for Marine Diesel Engine

Abstract

Marine diesel engine is the main power source of ship. Its safety and reliability can be improved by monitoring and diagnosing engine’s running status. A kind of Integrated multi-method multi-parameter Monitoring and Diagnosis (IMD) system for marine diesel engine is presented in the paper for the purpose of meeting the application in real ship environment. Test and information technology are fully reflected in the design of IMD system which can monitor the running status and diagnose a variety of common faults of marine diesel engine. IMD system contains six sub-monitoring systems which are Thermal Parameter Monitoring (TPM) system, Instantaneous Speed Monitoring (ISM) system, Cylinder Pressure Monitoring (CPM) system, Shaft Power Monitoring (SPM) system, Valve Leakage Monitoring (VLM) system and Piston Ring Monitoring (PRM) system.
