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 ...

This eliminates the confusion with the similarly-named rotary engines that had pistons in a radial configuration. These were widely used to power airplanes, as well as a few motorcycles and cars.

Transforming the up-and-down movement of a piston into a rotational one means losing some power due to friction, and that's why many engineers tried to create a rotary engine. But only one made it ...

Mercedes put serious research into the engine, and GM even believed that the rotary would supersede the piston engine in everything from the Vega to the Corvette. It appeared that the Wankel ...

The rotary engine has one thing in common with the traditional piston engine: internal combustion, and that's about it. Unlike a conventional internal combustion engine, which has cylinder banks ...

It is similar in concept to the discontinued Chevrolet Volt and BMW i3 REx, which used four-cylinder and two-cylinder piston engines. The rotary should be small, light and less intrusive than a ...

I love weird engines—give me a rotary, a turbine ... Spain had produced a opposed-piston engine that packed a pretty powerful punch in an extremely tiny package. There’s no cylinder head ...

The rotary engine is known for a lot of good ... in rotaries was because they have an inherent advantage over piston engines when burning hydrogen. Hydrogen is easily ignited, sometimes too ...

Rotary engines have almost completely gone out of production, but they’re still beloved by enthusiasts. Eschewing pistons for a spinning three-sided rotor, they rev to the moon and sound great ...
