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, ...

There are many different forms of internal combustion engines, but most use the same basic principle. Explosions in the combustion chamber move pistons up and down to spin a crankshaft. That ...

The rotary's reliability problem was mostly an owner problem. Here's the disciplined playbook that keeps FC 13Bs alive.

Despite electrification taking the lead as an alternative source of propulsion, some automakers, including Toyota, Honda, and ...

Astron aerospace has shown a partial prototype of a new rotary combustion engine it claims runs at an extraordinary 60% thermal efficiency, burning totally clean with zero NOx emissions and nothing ...

The rotary was the most radical rethink of the combustion engine in over a hundred years — and it paid the price for being different. Mazda introduced the innovative Wankel rotary engine in the 1967 ...

Tyler began his love for the automotive world from in front of a television screen, playing games like Gran Turismo and Need For Speed. While cars have always been his passion, he pivoted towards ...

Over-the-top rotary builds are an enthusiast tradition. Because so few rotary cars have been made, the limits of the engine type haven't been fully exploited by automakers. It's been tuners who have ...

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 ...

This video addresses common questions about the rotary vane engine, focusing on key aspects such as: - The relationship ...

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 ...
