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 ...

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

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

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 ...

Long before Felix Wankel became synonymous with rotary engines, an inventive Hungarian-American engineer named Stephen M. Balzer secured one of the earliest patents for a rotary-powered automobile on ...

Wankel engines first saw use in production cars as early as 1964 — and not even in a Mazda, but rather in an NSU. That little single-rotor powerplant quickly evolved into the more typical two-rotor ...

The electric motor might carry the hype banner at the moment, but some minds remain convinced that there's plenty of innovation left to be extracted from internal combustion. AIE is one of the rotary ...

As demands for sustainability ramp up, electric vehicle systems have become one of the major focuses of the engineering scene, with certain governments even hoping to gradually phase out traditional ...

Like it or not, the combustion engines that have driven our world forward and sideways for more than a century now are about to leave the scene. Not because they're no longer effective, but because ...
