Could there possibly be a rotary engine with 12 rotors? The answer is yes, and here's everything we know about it including ...

Astron aerospace has shown a partial prototype of a new rotary combustion engine it claims runs at an extraordinary 60% thermal efficiency, burning totally clean with zero NOx emissions and nothing ...

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 ...

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, ...

A Wankel engine is a type of rotary engine, but not all rotary engines are Wankel engines. Wrapping your mind around this idea will help you to better understand the similarities as well as the ...

Professor Aniebiet Inyang Ntui is a multi-faceted individual whose expertise spans the worlds of library and information science, environmental advocacy, and – perhaps surprisingly – the automotive ...

The latest reports, however, paint a different picture…again! I recently reported on a scoop from the Japanese publication, ...

Not every engine has a set of pistons that move up and down in a cylinder. The Wankel, or rotary engine, delivers its power with rotational force rather than a reciprocating mass that hammers out ...

The rotary was the most radical rethink of the combustion engine in over a hundred years — and it paid the price for being different. Mazda introduced the innovative Wankel rotary engine in the 1967 ...
