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 ...

When it comes to unique engine designs, one of the most prolific is the trusty rotary configuration. Instead of featuring a number of spherical cylinders moving up and down like in most internal ...

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 ...

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 ...

In a world dominated by pistons, the rotary engine was something different for motorists. It was the vision of German engineer Felix Wankel, built on the belief that the up-and-down motion of pistons ...

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, ...

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 ...

Over-the-top rotary builds are an enthusiast tradition. Because so few rotary cars have been made, the limits of the engine type haven't been fully exploited by automakers. It's been tuners who have ...
