Power stroke. As the piston reaches TDC on the compression stroke, an electric spark is produced at the spark plug.
做功行程：当活塞到达压缩行程的上止点时，火花塞产生电火花。
The piston travels down on the intake stroke, up on the compression stroke, down on the power stroke and up on the exhaust stroke.
进气行程，活塞下行；压缩行程，活塞上行；做功行程，活塞下行；排气行程，活塞上行。
On the compression stroke, the piston moves up. The intake valve and exhaust valve close. The piston compresses the air-fuel mixture.
在压缩行程，活塞向上运动，进气门和排气门关闭，活塞压缩混合气。
The result shows that tangent turbulence intensity is nearly the same from the outer to the center of the cylinder in the compression stroke.

By adjusting the linkage to allow a power stroke that is longer than the compression stroke, the engine can achieve greater efficiency than with the Otto cycle engine.
通过调整挂钩，使权力中风，比压缩冲程长，发动机可以达到，但与奥托循环发动机的效率。
In a diesel engine, there is no spark plug. Instead, diesel fuel is injected into the cylinder, and the heat and pressure of the compression stroke cause the fuel to ignite.
柴油发动机内没有火花塞，取而代之的是将柴油喷入发动机气缸，然后压缩冲程在高温高压下引起燃料点火。

本文作者在自制的压缩膨胀装置中模拟有涡流和无涡流情况下的柴油机压缩过程，并用高速摄影方法拍摄喷雾的扩展形态。
This does not mean that the plugs will wear at twice the normal rate, as the wasted spark is on the exhaust stroke, and is therefore under no compression.
这并不意味着活塞将以两倍于正常速度上下运动，因为浪费的火花出现在排气行程中，和没有任何压缩。
