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 ...

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 ...

heavy-fueled 25 hp rotary combustion engine that produces the same power output as piston diesel engines up to 10 times larger. Following its subcontract with Parsons, LiquidPiston received an ...

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 ...
