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 ...

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 ...

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.

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 ...
