The final step came when steam was introduced into the cylinder to drive the piston backward as well as forward, thereby increasing the speed of 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。

In continued operation the chain can jump a tooth on the drive sprocket or break entirely, with either case resulting in engine damage from valve-piston collisions.

在继续运作链可以跳转牙齿的驱动器上链轮或完全中断，与任何一种情况下造成的损害阀发动机活塞碰撞。

The simulation results show that the tracking error of middle-convex and varying ellipse piston linear servo drive system can be reduced effectively by this method.

仿真结果表明，采用这种控制策略可以十分有效地减小中凸变椭圆活塞直线伺服驱动系统的跟踪误差。

The efficiency of his design is further improved by using the moving piston to drive water through a special steam nozzle, which increases the effectiveness of the heat transfer between the inside and outside of the reactor.
