This 3D Printed Rotary Engine Is Genius

Checking Out A Working 1/3rd Scale Model Of A Mazda 13B-REW Engine!

The Wankel rotary engine was made popular by Mazda, who built rotary style engines from in production cars such as the RX-7, RX-8, and others from 1967 to 2012. The Wankel rotary engine is unique in that it has three main moving parts, in comparison to piston cylinder engines which have many more. There are two rotors, and a single eccentric shaft which all rotate, rather than reciprocating like four-stroke engines.

This video looks at a 1/3rd scale 13B-REW engine which Mazda used from 1992-2002 in the RX-7, and its power ranged from 255 to 280 horsepower. The two-rotor engine had a displacement of 1.3 liters, and sequential turbochargers.
