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.

In case you missed it, the automotive industry has been on a steady trajectory of internal combustion engine (ICE) downsizing for years. Battery-powered electric vehicles may capture most of the ...

We all know how a conventional internal combustion engine works, with a piston and a crankshaft. But that’s by no means the only way to make an engine, and one of the slightly more unusual ...

While diesel engines don't need spark plugs, they do need air ventilation for proper combustion. This is a problem for vessels traveling underwater, such as submarines. Yet diesel submarines exist and ...

The electric vehicle revolution gets all the headlines, and perhaps for good reason. What nobody mentions is that the global internal combustion engine market was valued at around $280 billion in 2024 ...

Researchers from Skoltech have published a paper in the journal Physica D: Nonlinear Phenomena presenting an analysis of steady propagating combustion waves—from slow flames to supersonic detonation ...

If you've ever driven a car into water that was deeper than you expected, you might have suffered the consequences of a submerged engine. While getting a car engine wet is no big deal, getting water ...

Automotive engineers have invested countless billions trying to improve upon the humble internal combustion engine, but not all those efforts have translated well. In fact, sometimes, things got weird ...
