Taking the WARTSILA RT-Flex 48 large-scale low speed high pressure common rail diesel engine as the research object,the model of exhaust valve control strategy is established by using Simulink.The function module is mainly composed of exhaust valve position monitoring,exhaust valve on/off state judgement,exhaust valve on/off angle calculation,exhaust valve on/off advance angle calculation,and exhaust valve control command output.The software in loop test is proceeded in the Silver virtual integration platform,the test result indicates that the designed control strategy model can achieve the desired functionality.%以WARTSILA RT-Flex 48大型低速高压共轨柴油机为研究对象,应用Simulink软件建立了排气阀控制策略模型,主要功能模块包括排气阀位置监测、排气阀开关状态判断、排气阀开关角度计算、排气阀开关提前角计算、排气阀控制命令输出.在Silver虚拟集成平台中进行了软件在环测试,测试结果表明所设计的控制策略模型能够实现预期的功能.
