RT-flex柴油机燃油共轨系统可视化仿真

Visual simulation for the fuel common rail system of RT-flex diesel engine

以RT-flex柴油机的燃油共轨系统为仿真对象,研究其工作原理和结构特点.对燃油共轨系统的高压油泵、中间储油器、燃油共轨管、ICU燃油流量控制活塞、喷油器建立数学模型.Simulink仿真结果表明所建数学模型基本正确.在VS2012平台下开发RT-flex柴油机燃油共轨系统的可视化仿真系统,系统能够形象显示燃油共轨系统的工作原理及运行状态,在轮机模拟器开发及人员培训方面具有应用价值.

With the fuel common rail system of RT-flex diesel engine as the simulation object , the working principle and structural features were studied .The mathematical models of high pressure fuel oil pump , intermediate fuel accumulator , fuel rail ICU piston as well as injector were established .Sim-ulink results show that the mathematical models are proper . The visual simulation system of the common fuel rail system in RT-flex diesel was developed by VS 2012 .The visual simula-tion system can display the working principle and running of the common fuel rail system , which is useful in developing marine engine simulator and training candidates .
