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

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
