What should drivers do if their vehicle suddenly shows signs of engine overheating while on the road? The answer is published ...

Heat engines convert heat into work—for example, moving a piston in a certain direction. For an engine to be 100% efficient, when the process is reversed—the piston returns to its original state—there ...

The internal combustion engines that power most modern cars generate huge amounts of heat as they run. While it's normal for your vehicle's engine to become quite hot while driving, too much heat can ...

Too low coolant temperature isn’t an immediately critical problem, but we explain why it’s still bad for your engine.

A study published in Physical Review Letters (PRL) details a "Gambling Carnot Engine" that researchers report can attain 100% efficiency while also improving power generation. The researchers present ...

A levitated bead is driven to behave like a heat engine, revealing strong fluctuations that seemingly defy thermodynamic principles. Video 1: A micrometer-wide particle (green) is held in a trap by ...

When something feels off with your car, it's always a good idea to pay close attention. Often, these small signs are hints that there's a bigger problem that needs your attention. For example, you ...

In one of the most unique DIY projects, Reddit user PickentCode has created what can be described as a completely off-the-grid "heat engine computing device." Instead of relying on solar panels or a ...

A numerical study of Boger ternary nanofluid flow between active parallel plates shows that plate contraction, radiation and ...

All vehicles become less efficient in cold weather. In a recent study, researchers in freezing Finland focused on whether engine block heaters could help increase efficiency in internal-combustion ...

This video demonstrates a working, power‑producing Stirling engine — an external combustion engine that operates without ...
