However, in a compressed air engine, no additional energy is gained if the air in the cylinder is compressed on the upward stroke of the piston.

然而，在压缩空气引擎，不需要额外的能源是涨，如果空气中的气缸压缩的向上中风活塞。

Blowby is basically the leakage of compressed air-fuel mixture and burned gases past the piston rings into the crankase.

窜气，基本上是被压缩的空燃混合气和燃烧后的气体的泄漏，它通过活塞环进入曲轴箱。

Power stroke: As the fuel is compressed and the piston nears the top of the cylinder the spark plug fires and ignites the fuel and air.

作功行程：活塞处于汽缸中的上止点，火花塞点燃充分压缩后的混合气体。

Instead of sparking the ignition when the piston is close to top dead center (when the air is compressed), that spark occurs as the piston is pulling away, when the air pressure is at its most turbulent, creating much faster ignition and more power.
