A Stirling engine is an external combustion engine that runs on the expansion and contraction of gas within a sealed system. In this video, we break down how it works, from heating and cooling cycles ...

For hundreds of years of human history, the invention that has defined our ability to travel, explore, and expand our boundaries has been the combustion engine. This hallmark of mechanical development ...

When we turn the key, what happens under the hood and why? How does an automobile engine work? What is that sound we hear and the propulsion we feel when the accelerator is depressed? We know gasoline ...

From a gearhead's viewpoint—take that back, anybody's informed perspective—there's one guy who stands out as a catalyst in the art of automotive as we know it. Not talking about the caveman who ...

The original concept of combustion engines as we understand them dates as far back as the late 1800s. And while they are more or less a solved science today, they definitely didn't start that way.

Because internal combustion engines operate under such high pressures, it's tough to get their inner workings on camera. Usually the whole process is shrouded by thick metals to contain all of that ...
