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, ...

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 ...

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 ...
