Pressure accumulates too, and so the mixture quickly explodes out from the chamber.
压力也在累积，所以导致混合物在室内快速发生爆炸。

PCV system will be a mixture of leaking into the crankcase leap into air intake system in the combustion chamber, then a second combustion.
PCV系统将窜漏进曲轴箱的混合气引入进气系统，然后在燃烧室内进行二次燃烧。

Increasing the pressure of the fuel mixture in the combustion chamber before ignition helps to increase the power of an engine. This is done by compressing the fuel mixture to a smaller volume.
