The four-cycle, or Otto cycle, engines that powers today's cars derived from designs attributed to pioneers like Nicholaus Otto, for whom the Otto cycle is named. Otto received a patent for his design ...

As the global push for carbon neutrality accelerates, managing the massive energy demands and waste heat of industrial sectors has become a critical challenge. Industrial energy systems currently ...

A long-standing law of thermodynamics turns out to have a loophole at the smallest scales. Researchers have shown that quantum engines made of correlated particles can exceed the traditional ...

Adaptive cycle engines are specially designed to alternate between efficiency and raw power—extending an aircraft’s range without compromising on speed during engagements. The modern fighter jet is ...

Scientists develop a microscopic heat engine that achieves 100% efficiency, accomplishing what seemed impossible. A new theoretical design describes a tiny heat engine that can convert all of the heat ...

Engineers at the University of California, Davis, have built a small device that produces mechanical power at night by exploiting the contrast between ambient warmth and the extreme cold of outer ...

Mazda's Miller-cycle engine was a notable entry in the annals of automotive history, combining variable valve timing with a screw-type supercharger to maximize the brief compression cycle. The most ...

The Mazda CX-90 feels like a bona fide luxury SUV, but the company's current upmarket push isn't its first. At one time, Mazda was actually going to launch its own luxury sub-brand, and it would bring ...

Two physicists at the University of Stuttgart have proven that the Carnot principle, a central law of thermodynamics, does not apply to objects on the atomic scale whose physical properties are linked ...

A team in Japan has harnessed non-thermal quantum states to break classical thermodynamic limits, converting waste heat into electricity with record efficiency. Credit: Stock Researchers have ...
