This fan can suck air in and pressurize the motor creating boost.

这个风扇可以吸入空气并给电机加压以产生增压。

Now a supercharger really is the same concept, it's pressurizing the motor, it's forcing air and fuel into the motor, but it uses a belt and a crank off the crank shafts.

增压器实际上是相同的概念，就是给电机加压，它迫使空气和燃料进入电机，但它使用皮带和曲轴上的曲柄。
