First up from tadproletarian, " How do search engines work so fast? "

首先从 tadproletarian 的问题开始，“搜索引擎如何工作得这么快？”

And we've had complete re-architecture of how jet engines work.

我们已经对喷气发动机的工作方式进行了彻底的重新设计。

I do enjoy finding out how earthquakes actually happen and why they happen and how combustion engines work.

在了解地震发生原因和引擎工作原理的过程中，我很享受。

Experts say that the data collected during the process are enough to ensure the engine works smoothly during the real launch.

专家表示，在此过程中收集的数据足以确保引擎在实际启动过程中平稳运行。

The plane could still fly with only 2 engines working.

这架飞机仍然可以在只有 2 个引擎工作的情况下飞行。

The engines worked for about 22 minutes, moving the pair into a moon-Earth transfer trajectory.

引擎工作了大约 22 分钟， 使这对飞船进入了月球-地球转移轨道。

To make a steam engine work, coal is burnt to heat water, and this makes steam.

为了使蒸汽机工作，煤被燃烧以加热水，从而产生蒸汽。

They were only about halfway through their trip to Edmonton, and with only one engine working, they decided to divert to nearby Winnipeg for an emergency landing.

他们到艾德蒙顿的行程只走了一半，这时只有一个引擎还在运行，他们决定转移到附近的温尼伯紧急降落。

With all that in mind, here’s how a Carnot engine works – at least in theory, because again: Carnot engines are totally hypothetical.

考虑到所有这些， 卡诺引擎是这样工作的——至少在理论上是这样， 因为：卡诺引擎完全是假设的。

First, when accelerating to higher speeds during the pulse, the engine works at a higher efficiency compared to traveling at a constant lower speed.

首先，当在脉冲期间加速到更高的速度时，与以恒定的较低速度行驶相比， 发动机的工作效率更高。

First, without any engines working, their plane was making almost no noise, and so people on the ground at the racetrack had no warning of their sudden landing.

首先，由于没有任何引擎能工作，这架飞机几乎发不出任何声响，所以赛车道上的人们不知道他们会突然降落。

To build upon a previous example, remembering where you parked your car is an example of episodic memory, but your understanding of what a car is and how an engine works are examples of semantic memory.

继续我们刚才的那个例子，记住你在哪里停车是情节记忆，而你对于什么是车以及引擎是怎样工作的是语义记忆的例子。

Tail-mounted engines work much as any powerplant. They take in lots of air, compress it, add fuel and ignite it. They then expel the  resulting gases out the back at a very high speed.

尾部安装的发动机与任何动力装置一样工作。他们吸入大量空气，压缩它，添加燃料并点燃它。然后，它们以非常高的速度将产生的气体从背部排出。
