The idea is to oscillate the turbocharger's variable geometry and synchronise it with the engine exhaust to get better energy recovery from the pulsating exhaust flow.

这个创意是通过调节涡流增压器的结构来使它与引擎尾气排放同步，从而达到更好的能量回收效果。

To supply the extra juice, utilities turn on inefficient single-cycle gas turbines, which turn 25% of the fuel's energy into electricity, as opposed to 45% for combined-cycle plants that use turbine exhaust to make steam to run a second generator.
