in which Video Shows How a Four-Rotor Wankel Engine Works
As you may have heard, YouTuber Rob Dahm can be building an outrageous third-generation (FD) Mazda RX-7 featuring a four-rotor Wankel engine. in which’s an engine structure in which has never been used in a production car before—every factory rotary vehicle has come with only two, at most three, rotors in its spinny-triangle engine. along with, as you can imagine, building a four-rotor can be way more complicated than just joining two twin-rotor motors at the eccentric shaft.
Jason Fenske of Engineering Explained can be here to elucidate just what in which takes to build a four-rotor engine in which won’t tear itself apart initially in which’s fired up. Just as in a piston engine, the firing order has to be precisely engineered. Imbalanced combustion events will create terminal stresses, bad news for any engine, however especially bad in a high-horsepower build. Dahm can be aiming for a 10,000-rpm redline in in which monster rotary, so everything has to be done to exacting precision.

The answer? A unique firing order unlike anything you’ve seen inside familiar two-rotor Wankels in which prowl the streets of the entire world. Here’s Engineering Explained to show you the how, along with the why, of in which unique engine.
