Which Cars Have Rotary Engines?
2 Answers
Mazda, as the only automaker in the world to have mass-produced rotary engine models, offers several vehicles equipped with rotary engines, including the RX series of rotary sports cars. Cars with rotary engines include: 1. Mazda RX7. 2. Mazda RX8. Information about rotary engines is as follows: 1. Structural Principle: In a rotary engine, the expansion pressure acts on the sides of the rotor, pushing one of the three faces of the triangular rotor toward the center of the eccentric shaft. This movement occurs under the influence of two component forces: a centripetal force directed toward the center of the output shaft and a tangential force that causes the output shaft to rotate. 2. Advantages: The rotary engine eliminates useless linear motion, so compared to a linear reciprocating engine of the same power, the rotary engine is smaller in size, lighter in weight, has a lower center of gravity, delivers greater power output, and produces lower vibration and noise.
As a longtime car enthusiast, I have a particularly deep impression of rotary engine vehicles. Mazda was the only mainstream automaker that truly mastered this technology. The 1960s Cosmo Sport was the pioneer, but it was the RX series that really brought rotary engines into the public eye. The RX-7, beloved by veteran enthusiasts, has two legendary generations - the FD and FC, with their twin-turbo sound being simply amazing. The later RX-8 was quite interesting with its unconventional four-door suicide door design, though production ceased completely after 2012. Mercedes-Benz actually experimented with the C111 prototype, but it never reached mass production. Nowadays, if you want to experience rotary engines, you're basically limited to finding used RX-8s in the secondary market - though maintaining those triangular rotors is truly expensive, and fuel consumption is significantly higher than piston engines.
