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 ...

Most of the internal combustion piston engines built for vehicles throughout history have pretty familiar core designs. The majority of fuel-burning vehicles sold today orient their pistons in inline ...

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 ...

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 ...

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, ...

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 ...

Automotive engineers have invested countless billions trying to improve upon the humble internal combustion engine, but not all those efforts have translated well. In fact, sometimes, things got weird ...

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 ...
