It expands. You change your constraints on your system, you heat it up some more, then you take the heat source away, and you put it back in contact with the atmosphere. And you cool it a little bit, change the constraints, cool it a little bit more, and heat, and you've got a closed cycle engine.

让它与大气接触冷却,改变约束，使它继续冷却，然后又再次加热,这就是循环热机，我们以前也研究过，更复杂的机器。

Now what I want to do is put up a specific example of the cycle that can be undertaken inside here in an engine, and we can just calculate from what you've already seen of thermodynamics.

现在我想做的是,举一个例子,来具体说明热机内部的循环过程，同时我们可以利用热力学定律进行计算,看看热力学参量发生了什么变化。

So the way I've got things written here, q1 Heat's flowing from the hot reservoir to the engine that runs in a cycle.

我把这些都这些这里，是正的，q1，is，positive,热从高温的热源,传到循环工作的热机，对外做功。

For years he had contemplated the inefficiencies of the traditional four-stroke Otto cycle engine (named for its 1876 developer, Nikolaus A. Otto).

FORBES: How To Get 50 MPG Out Of Your Gasoline Engine

Scuderi says its split-cycle engine increases overall efficiency by up to 50 percent and cuts down on NOx gases at the same time by changing the way air gets channeled through an engine.
