A technology company has broken the world record for the overall thermal efficiency of a diesel engine, which could save ...

The Stirling engine has the highest theoretical efficiency of any thermal engine. It is also a relatively simple machine. Unlike other types of engines, there are no valves, and that makes the ...

While developing electric engines, Porsche continues to work on thermal engines. It has just imagined a 6-stroke engine.

In this video, we cold start a 2016 Subaru Crosstrek and use a thermal camera to watch the engine heat up. It’s -6°C (22°F) outside. We monitor engine RPM (higher at startup), throttle ...

Planets can be understood as thermal engines that are in some ways similar to steam engines. When the planets were formed, they were heated by the impacts of the planetesimals that collapsed upon them ...

The trinational Global Combat Air Program team is confident it can deliver the power the new aircraft demands without the complexity of an adaptive propulsion system. Seeking to achieve unprecedented ...
