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 ...

The engine. It's a testament to its initial design, as whether it's in a V-configuration, W, H, or even flat, it really hasn't changed its operation since its invention. That is, of course, except for ...

When considering rotary engines, the Wankel engine often comes to mind due to its high power-to-weight ratio, though it ...

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 ...

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 ...

The rotary engine is easily one of the most controversial powertrains in the world of cars, and it's known for the brap-brap ...
