But what if you were to combine some genetics from piston engines and Wankels, then put them into one engine? Meet the Birotary, a crazy new and complicated engine that has three cylinders arranged ...

The Rotating Detonation Engine being developed by Pratt & Whitney has no moving parts, which reduces complexity and costs, and could help enable high-speed, long-range flight with increased efficiency ...

There have been published papers by the Air Force Research Lab and NASA on rotating detonation engines having 10% or more efficiency gains. A rotating detonation engine (RDE) uses a form of pressure ...

In the era of downsizing, automakers are gradually moving away from high-cylinder engines. As a result, they are increasingly in favor of smaller, often turbocharged or hybridized powertrains. A few ...

Four-cylinder engines have been part of the automotive scene for over a century. Yet the quest for more power under the hood dominated most of the 20th century, giving rise to six- and eight-cylinder ...
