| Abstract:Based on the common rail system of a marine diesel engine with the function of abnormal leakage isolation and detection，the AMESim simulation platform was used to build a simulation model of the abnormal leakage oil path of the system.Through simulation analysis，the structure and flow capacity of the oil path were optimized to meet the requirements of the pressure safety of the leakage oil path.Combined with the spatial structure layout of the common rail system，the abnormal leakage detection points of the system were analyzed.The inference relationship diagram of leakage detection points，leakage sources and replaceable units was given，and on this basis，the system abnormal leakage isolation detection process was formed to provide reference for similar products. |
