电控可变流道截面，由ECU读取发动机信息，通过控制电控执行器来调整涡轮箱内拨片与流道壁的角度，调节流道截面，使进气量更符合发动机状态。适用于国五、国六排放要求的发动机。
With electronic control the turbo geometry is variable , read the engine information by the ECU, it will adjust the angle between the interal shift fork of turbine housing and the wall of flow route by electric actuaor,thus adjust the section of flow route，provide suitable air flow to the engine, apply to CN 5\CN 6 diesel engine.应用于柴油发动机
