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, ...

Wankel rotary engines, typically but not exclusively found in Mazdas, certainly lean on the "quirkier" side of modern powertrain systems, made quirkier because most rotary-powered cars on the road ...

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 ...

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 ...

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 ...

Good news, everyone! Mazda is not only reassembling a dedicated team of engineers for rotary engine development, as we’ve reported earlier, but today it also announced its intention to expedite ...

The 1974 Mazda REPU was the world's only mass-produced rotary pickup truck, featuring a 1.3L Wankel engine with 110 hp and ...

Why did Wankel rotary snowmobile engines disappear? A look at Arctic Cat’s rise and fall with this once-promising technology.
