| With the development of computer technologies, electronized, intelligentized and informationized have been used more and more in the control and management of marine diesel engines. It sharply reduces the atmosphere pollution and greatly improves the reliability and economic efficiencies of the ship by applying the marine electronic diesel engine as main engine. In this dissertation, the servo oil common rail system of Wartsila RT-flex electronically controlled diesel engine is taken into study. Firstly, it mainly interprets common rail system of large marine low-speed two-stroke diesel engine, which includes servo oil pump, servo oil common rail, and exhaust valve drive system, and introduces Wartsila Engine Control System (WECS-9520 control system)’s composition, working principle, and the control functions. Secondly, basing on hydro-mechanics control equations and the equations of the components’motion and state, the mathematical models of the system are established in modularized methods. And the Matlab/Simulink software is chosen to be the simulation tool. The results of simulation are verified. The result of simulation shows that this paper built the model of servo oil common rail system is a correct simulation model, and the simulation results consistent with the actual law system. On the foundation of established models, the first set of servo oil common rail system simulation system is developed through computer programming language. Using the Visual C# programming language, the simulation software is developed successfully. The successful development of the system will promote engineers’training, who served on ship with Wartsila RT-flex’s main engine. |
