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 ...

Hydrogen combustion engines are inefficient, costly to maintain and worse for the environment than fuel cell or battery powertrains. But they're also noisy and fun, so automakers are starting to pitch ...
