Chinese firm Dongan Auto revives the Wankel engine, developing a lightweight prototype aimed at next-gen aerial mobility ...

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 ...

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 ...

A Wankel engine is a type of rotary engine, but not all rotary engines are Wankel engines. Wrapping your mind around this idea will help you to better understand the similarities as well as the ...

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 1970s were full of strange automotive experiments, but few were as unlikely as a compact Japanese pickup powered by a ...

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, ...

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 ...

How the 13B-MSP Renesis evolved from earlier Mazda rotary designs, technical features explained, and common problems and maintenance issues discussed. The 13B-MSP Renesis rotary engine powered the ...

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 ...

Changan’s R05E prototype achieves first ignition, signaling renewed interest in rotary engines but for a wilder application.

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 ...
