The internal combustion engine, for all its mechanical sophistication, still runs on a 19th-century mechanical idea: pistons rising and falling, a crankshaft spinning, a steam-age architecture ...

Warped Perception — a channel dedicated to putting a fun spin on science, engineering, and technology — has been known to feature miniature engines to give viewers a better understanding of how the ...

The rotary engine is unique in its success and failure and its ability to make an impact with a completely different way of thinking. As it is, every production car for the last 130 years, aside from ...

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 ...

Rotary engines are already known for their high RPM; the smaller they get, the higher they tend to rev. So what happens when the world’s smallest rotary engine gets put to the test? Well, 30,000 RPM ...

Rotary engines, known for their unique design and compact size, have been predominantly associated with Mazda. However, engineers and automotive enthusiasts have experimented with incorporating these ...

You hear endless myths about the Mazda RX-7, from breathless praise of its “magic” to horror stories about blown apex seals. Strip away the fanboy noise and you are left with a very specific kind of ...

Rotary might be a good name for this sort of engine, if the name wasn't already taken. Everything inside the crankcase rotates, but unlike a Wankel-style rotary engine, this design uses a piston with ...

Do you remember Gulliver's first voyage to the island of Lilliput? The indigenous people there were less than 6 inches (15 cm) tall. That's almost twice the length of a Hot Wheels diecast vehicle.

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 ...

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 ...

Language is an imperfect medium, but it's what we've got, so let's go with it. Determining the swept volume of inventor Felix Wankel's rotary engine can generate more arguments than claiming what a GT ...
