摘要:Abstract In this paper, physical models for the cooling and the lubricating systems for marine diesel engine have been developed. The main purpose of this modeling is to integrate some possible faults that may be produced, and then to analyze their effects on the overall marine diesel engine during operation. Faults may appear in the model as the variation of some parameters. The importance of this study is to prepare an important data base for the fault diagnosis and prognosis strategies that may be applied on Diesel engines. Experimentations on Marine Diesel engine test bench have been used for the validation of the proposed model.
