Procedures for “breaking in” new, remanufactured or rebuilt engines are evolving. Standard procedure in past decades was to use break-in oil in a “new” engine for the first 100 hours. During that time ...

Evaluation of the combustion process in a wall-wetting direct-injection diesel was accomplished by calculation of the apparent rate of heat release from the measured pressure history for several ...

The quantum advantage: Coherent superposition in quantum heat engines can enhance power output over classical machines. Credit: iStock Traffic-Analyzer Heat engines have had a huge impact on everyday ...

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 recent study led by Chinese scientists has challenged the hundreds-of-year-old myth that a heat engine can achieve both ...

Ytterbium silicide (Yb-Si) is a promising coating material for the high-temperature sections of aircraft gas turbine engines. Although Yb-Si is heat-resistant and prevents formation of structurally ...

Since it is essential to design an aircraft engine nozzle to achieve IR signature suppression, an S-shaped nozzle (double serpentine nozzle) is applied so that the high temperature part of the engine ...
