What is a rotating engine?

Answer 1

A rotating engine, often referred to as a rotary engine, is a type of internal combustion engine where the combustion process occurs in a chamber that rotates around a central axis. Unlike traditional piston engines, which utilize reciprocating motion, rotary engines utilize a triangular rotor that moves in an elliptical path, allowing for a more compact design and fewer moving parts. This design enables smoother operation and the potential for higher power-to-weight ratios, although it may face challenges related to efficiency and emissions. Notable examples include the Wankel engine, commonly used in some Mazda vehicles.
