It USES a fast actuated nozzle to follow the exhaust pulse, reducing the turbine inlet area periodically to increase exhaust-gas pressure.
涡流增压器采用了一个快速响应喷头来跟踪尾气脉冲，减少内燃机的进气周期，从而增加尾气排放压力。

The method, based on the theory of non-symmetric flow in Lavol nozzle, aims first at the Angle of reducing the gas dynamic misalignment, and then at the Angle of efficiency.
这种方法以拉伐尔喷管内非对称流动理论为基础，首先着眼于减少气动偏心，然后考虑效率。
