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 this video, I explore a novel rotary engine design that addresses the sealing challenges of traditional rotary vane engines. My new design features two half-moons within an ellipse that allow for ...

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, ...

Everyone generally knows about piston and rotary engines, with many a flamewar having been waged over the pros and cons of each design. The “correct” answer is thus to combine both into a single ...

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 ...

Nematic liquid crystal elastomers (NLCEs) could perform as soft actuators because they generate greater contraction stress than ordinary rubber in response to a temperature rise of several tens of ...

When it comes to unconventional engine design, few exceed the Wankel rotary in terms of weirdness. Despite that, the same basic principles of internal combustion apply here: Fuel and air are mixed and ...
