How Wankel Engine Works | Mechanical Engineering World

We discuss the fascinating Wankel rotary engine, which works without pistons or a crankshaft. This unique engine was famously used in Mazda's RX-7 and RX-8 models, providing a distinctive sound and explosive acceleration. While the rotary engine had issues with fuel efficiency and emissions, leading to its decline, some companies are now bringing it back as a range extender for electric vehicles, taking advantage of its compact size and high-revving capabilities. | Auto Viral

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
