Rotary engines (also known as Wankel engines and Wankel rotary engines) are quite different from piston or "reciprocating" engines. One of the distinguishing features is that they don't need valves to ...

How does a rotary engine work? Wankel Engines. Explanation of how a rotary engine works. With only 3 moving components, these are an engineering marvel. A look inside at what actually happens.

In this video, we address several common questions regarding the rotary vane engine and its design, including: 00:00 ...

Everyone generally knows about piston and rotary engines, with many a flamewar having been waged over the pros and cons of each design. The “correct” answer is thus to combine both into a single ...

The electric motor might carry the hype banner at the moment, but some minds remain convinced that there's plenty of innovation left to be extracted from internal combustion. AIE is one of the rotary ...

In theory, Wankel-style rotary internal combustion engines have many advantages: they ditch the cumbersome crankcase and piston design, replacing it with a simple, single-chamber design and a thick, ...

When it comes to unconventional engine design, few exceed the Wankel rotary in terms of weirdness. Despite that, the same basic principles of internal combustion apply here: Fuel and air are mixed and ...
