Load change in the engine intake manifold pressure changes that is when the spooldisplacement greater, gas output in response to faster.
在发动机负荷变化即进气管压力变化时，阀芯的位移更大，燃气输出量的响应更快。

The valve is driven directly by a large strake multilayer piezoelectric stack, its displacement actuates the power cascade spool after amplification by a lever mechanism.
该阀采用大行程的压电叠堆作为驱动元件，经杠杆放大后的位移直接驱动功率级滑阀。

Adjusting mechanism is the executive body converts the output of displacement control valve spool and valve seat area change between the flow of the device.
