The engine with no pistons. In 1957, engineer Felix Wankel did the unthinkable. He built a working rotary engine that had no pistons at all. Instead of cylinders firing up and down, it used a spinning triangle inside an oval chamber to generate continuous power with fewer parts and smoother motion. Mazda was the only car maker crazy enough to mass produce it, and they turned it into the RX-7, a lightweight sports car with a tiny engine that revved like a motorcycle. At just 1.3 liters, the Wanke

How Rotary Engines Work

We talk about the Wankel rotary engine, one of the most unique and fascinating engine designs in automotive history. Instead of traditional pistons, it uses a triangular rotor that orbits inside an oval chamber to create combustion in a smooth, continuous motion. This makes it lightweight, high-revving, and compact, but it also came with challenges like poor fuel efficiency and sealing issues. | Auto Viral
