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 ...

A team of researchers including Princeton computer scientists has developed a new tool that simplifies the process of animating still images, such as this diagram of an external combustion engine.

The stringent emission regulations for Internal Combustion Engines (ICEs) spawned a great amount of research in the field of innovative combustion approaches characterized by high efficiency and low ...

Astron aerospace has shown a partial prototype of a new rotary combustion engine it claims runs at an extraordinary 60% thermal efficiency, burning totally clean with zero NOx emissions and nothing ...

Carbon emission-free engines that burn hydrogen increasingly look like a viable technology for vehicles that range from race cars to cement mixers. The motorsport department at Austrian automotive ...
