Both rotary engines and piston engines utilize internal combustion and share the same phases of intake, compression, power, and exhaust. But beyond this similarity, they are very different in ...

Through the history of internal combustion engines, there has been plenty of evolution, but few revolutions. Talk of radically different designs always leads to a single name – Wankel.

As interesting as this concept is, it still has a long way to go before reaching production lines, not to mention its applications may be limited ...

That means the next-generation rotary will likely feature reduced internal friction and lightweight internals in a quest to reduce emissions and increase fuel economy. But the engine may find ...

Primarily, they’re smaller and lighter than other combustion engines for a given output, and with rotating rather than reciprocating internals, considerably smoother too. The idea of a rotary ra ...

That is bad news for fans of internal combustion engines. The chances are slim that a car model that runs solely on a rotary engine will ever roll off the assembly line again. One senior Mazda ...

or rotary, engine. If you ever wondered how these worked, why not print a model? That’s what [Engineering Explained] did. They printed a 1/3 scale model and made a video explaining and ...

The issue, as it has pretty much always been, is environmental. While the Wankel rotary engine does indeed make a lot of power in a small, lightweight package, it does so while burning lots of ...

The iconic rotary car engine, thought to have been consigned to the dustbin of impractical technology, is making a comeback in Japan from the very automaker that introduced the system as far back ...
