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 engine is perhaps one of the most polarizing motors to have ever been commercialized. From its checkered past to its intent to live on as a range extender, the small spinning triangle has ...

Professor Aniebiet Inyang Ntui is a multi-faceted individual whose expertise spans the worlds of library and information science, environmental advocacy, and – perhaps surprisingly – the automotive ...

Rotary engines (also known as Wankel engines and Wankel rotary engines) are quite different from piston or "reciprocating" engines. One of the distinguishing features is that they don't need valves to ...

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 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, ...

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 ...

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 ...

Alina has been enthusiastic about vehicles her entire life, and even from an early age found herself itching to get behind the wheel. Through high school and college, she could be found reading ...

Looking at all the incredible machines roaming our roads these days you’d be inclined to believe it can’t get better than this when it comes to the combustion engines they use. But if you ask a crew ...
