...并在机械增压的作用下保持一定的压力，因而在下一次进气冲程中的引擎的进气效率会大大增加并降低所谓的Pumping loss（泵吸损失）配合较高的膨胀比，从而得以输出相当不错的功率；而另一方面，由于一部分气体回到进气歧管中，引擎过高的压缩比会得以适当降低，...

pumping gas loss 泵气热损失
The traditional gasoline engine regulates inflow gas by throttle. At low load condition large pumping loss leads to high rate of fuel consumption.
传统汽油机靠节气门调节进气流量,小负荷时节气门开度小、泵气损失大,导致燃油消耗率过高；配气机构的凸轮型线固定不变,不能兼顾全部工况下的进气需要。
