Is there a better way to learn how a rotary engine works?
On this episode of Engineering Explained, Jason Fenske explains how the wankel rotary engine works. Using a 3D-printed 1/3 scale model of a 13B-REW engine from an FD Mazda RX-7, we get a closer look at how rotaries function. The wankel rotary engine was first used by Mazda when the company debuted the Cosmo back in 1967. It was later used in pickup trucks, but didn’t gain popularity until it found its way into the first generation RX-7 in 1978. From there, rotary engines and the RX-7 name became synonymous until the final production of the RX-8 in 2012.
