This video provides an in-depth analysis of the liquid piston engine and compares it to traditional piston engines and Wankel ...

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 into a single ...

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 ...

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 was the most radical rethink of the combustion engine in over a hundred years — and it paid the price for being different. Mazda introduced the innovative Wankel rotary engine in the 1967 ...

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 ...

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, ...

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 ...

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 ...

Rotary engines tend to conjure images of a few famous sports cars, yet a surprising number of coupes, sedans, concepts, and even workhorses quietly packed spinning triangles under their hoods. By ...

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 rotary engine has been a Mazda staple since 1967. It powered one of the most famous and eccentric Japanese sports car line-ups, the RX-series, until 2012 when Mazda discontinued pure ...
