Heat is a byproduct of combustion. Both air-cooled and water-cooled engines need to dissipate that heat to keep the engine from running too hot. Can piston rings play a role in managing that heat?

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 ...

Scientists in Sweden experimentally evaluated a Stirling engine–based Carnot battery (SECB) prototype using low-cost sand as ...

Heat engines are thermodynamic physical systems that convert heat energy into mechanical work by exploiting a temperature difference between a high-temperature heat source and a low-temperature heat ...

Developed by Chinese researchers, the system is designed to reach a heating capacity of 5.7 kW and an overall coefficient of performance of 1.40 at nominal conditions. It is made with an engine unit, ...
