The Carnot engine is the ideal engine, because it produces the most possible work from a given temperature difference.

卡诺发动机是理想的发动机，因为它产生 给定温差的最可能动作。

But we can imagine an ideal engine, where none of the exhaust energy is waste heat – where there’s no friction or anything like that.

但我们可以想象一个理想的发动机， 其中没有任何废气能量是废热——没有摩擦或类似的东西。

但我们可以想象一个理想的引擎，其中 废热不是废热——哪里。

An ideal engine would also be reversible – meaning, you could run it backward, putting in work to transfer heat from something with a lower temperature to something with a higher temperature.

没有摩擦或其他任何东西。完美的引擎 可逆，这意味着您可以打开它。
