Mazda’s 13B rotary engine did more than power a string of sports cars. It forced an entire engineering department to think differently about combustion, packaging, and character, and it left a mark on ...

Mazda made a splash in the market in 1990, launching the Eunos Cosmo with the three-rotor 20B engine. Compared with contemporary Wankel rotary engines, the 20B's extra rotor beefed the compact ...

The Wankel rotary engine offers one of the most unique sounds of any ICE. Most famously used in various legendary Mazdas like the RX-7 and the supposedly banned Le ...

Almost every internal combustion vehicle on the planet today uses the classic piston engine. These run by converting heat energy into reciprocating motion, and then rotary motion that ultimately ...

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 ...

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 ...

Language is an imperfect medium, but it's what we've got, so let's go with it. Determining the swept volume of inventor Felix Wankel's rotary engine can generate more arguments than claiming what a GT ...
