The Wankel engine—also known as the rotary piston engine—was designed by Felix Wankel in the 1920s and entered mass production with NSU in the 1950s. Unlike piston engines, it is an internal combustion engine that rotates around an eccentric shaft within a triangular rotor, an epitrochoidal cylinder, and performs four simultaneous processes—intake, compression, combustion, and exhaust—in separate chambers. The rotor's three faces form combustion surfaces at a 120° angle; each cycle involves thre

First start-up after winter on this Norton Rotary Cafe Racer owned by our friend Dave Brown. The starting point for this project was a 1988 Norton Commander with a Norton Wankel Rotary engine. Some other interesting features include a Kawasaki ZX7R front end, Manx Norton tank and Norton F1 tail fin. There’s a full length video on this bike over on The Classic Motorcycle Channel if you’re interested. Thanks to Dave for sending us the video. @nortondavid7 #nortonrotary #nortonwankel #nortonmotorcy

The Trusty Tractor, produced by Tractors (London) Ltd from the 1930s until 1962, was a versatile two-wheeled agricultural machine designed for smallholders and gardeners. Over its production span, it utilized various engines, including those from Villiers, JAP, and notably, the Norton Big 4. The Norton Big 4 engine, a 633cc side-valve single-cylinder unit, was originally developed for motorcycles and later adapted for industrial applications. In the Trusty Tractor, this engine was modified to in
