ABSTRACT
In order to observe the dynamic performance of servo oil Common Rail System of marine intelligent diesel engine, 7RT-flex 60C diesel engine is selected as the research object to analyze the characteristics of common rail system. Based on the continuity equation and the motion equation of the fluid mechanics, the mathematical models with blocks are established for servo pumps, collectors, common rail of servo oil and vent control module, etc. All the mathematical models are calculated by MATLAB/Simulink for the rail pressure of collector and servo oil common rail, servo pump plunger stroke, plunger cavity pressure and flow, front chamber pressure and the displacement of piston, exhaust valve lift, etc. to achieve the dynamic simulation and parameter analysis. Finally, the simulation results of curve and data are compared with the basic characteristics of actual servo oil common rail system to verify the correctness of the model.
