The motor rotativo, commonly known as the rotary engine, is an internal combustion engine that uses a rotating design to convert pressure into a rotating motion. Instead of using pistons that move linearly as seen in traditional engines, the motor rotativo employs a triangular rotor that orbits in an epitrochoidal motion within a chamber. This design has led to compact size, reduced vibration, and increased power density. The most notable example is the Wankel engine, which has been used in various applications, most famously in Mazda vehicles. Over the years, the development of motor rotativo has encountered numerous innovations and challenges, transitioning from niche applications to mainstream automotive use and even experiments in aviation and other fields.
