When people say rotary engine, they usually mean Wankel. Mazda put it in some of their coolest cars, and recently in the MX-30 REV, though there it does the most humiliating job ever: it's a range ...

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, ...

I have not given up on making a weird novel-type engine run, and I come one little step closer to my goal. What I have given up on, for the time being, is the rotary vane engine. After my last attempt ...

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 ...

Rotary engines differ from conventional ones in many respects — and one of them is the fact that they use two different spark ...

Rotary engines have an aura of cool. In games of Top Trumps, the V12 might have been king, but a rotary was a joker, a wild card. A lack of mainstream success no doubt contributes; there are reasons ...

Antonio is a chemical engineering student pursuing his master's degree in chemical engineering and sustainable processes. Throughout his academic journey, he has gained substantial knowledge in areas ...

For a time, the Wankel rotary engine seemed like the future. In 1963, German automaker NSU—later absorbed into Audi—debuted the Wankel Spider, the first internal-combustion production car not powered ...

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 ...

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 ...
