The final step came when steam was introduced into the cylinder to drive thepiston backward as well as forward, thereby increasing thespeedof the engine and cutting its fuel consumption.
最后一步是将蒸汽引入气缸，使得活塞前后推动，从而提高了发动机的速度，降低了燃料消耗。

Reciprocating pumps convert rotary motion to linear motion. Pump speed in RPM determines the pumps output volume for any given combination of cylinder bore and piston stroke.
循环泵将曲轴旋转运动转化为柱塞的直线运动。泵速转每分钟决定了任何气缸和活塞组合的排泵量。

The optimized combustion chamber accelerates the transferring speedofthe flame, prevent the deflagrating, even the heat transfer on the piston and lower the amount of the exhausting.
