What are the representative models of rotary engines?
2 Answers
Representative models of rotary engines include the Mazda RX-7 and Mazda RX-8. The working principle of a rotary engine is to directly convert the combustion expansion force of combustible gas into driving torque. Compared to reciprocating engines, rotary engines eliminate useless linear motion, resulting in smaller size, lighter weight, and lower vibration and noise levels. Taking the Mazda RX-8 as an example, it is a hardtop sports car with the following body dimensions: length 4460mm, width 1770mm, height 1340mm, wheelbase 2700mm, front track 1500mm, rear track 1505mm, minimum ground clearance 120mm, fuel tank capacity 65L, and trunk capacity 284L.
When it comes to iconic rotary engine models, the first that comes to my mind is Mazda's RX series, especially the RX-7. I've been obsessed with cars since childhood and had the chance to drive a friend's RX-7 FD3S version—it was absolutely mind-blowing. The rotary engine is completely different from conventional piston engines; its triangular rotor spins incredibly smoothly, producing a sharp, race-car-like sound with intense acceleration and strong G-force. Mazda began mass-producing it in the 1970s, turning the RX-7 into a street legend. However, it has notable drawbacks, like higher fuel consumption and faster engine wear, requiring more frequent maintenance. Later, the RX-8 was introduced to address environmental concerns, but it was eventually discontinued. If you're into niche performance cars, the RX series is definitely worth a deep dive—it's a classic masterpiece of automotive innovation.
