From its humble beginnings to its global influence, RE Amemiya is more than a tuning shop—it’s a testament to the artistry and potential of rotary engines.
This blog explores the history of RE Amemiya, the brilliance of rotary engines, and how the workshop became a beacon for enthusiasts worldwide.
The Beginnings of RE Amemiya: Isami Amemiya’s Vision
Isami Amemiya, the mastermind behind RE Amemiya, established the shop in 1974 in Chiba Prefecture, Japan. The name “RE” stands for Rotary Engine, reflecting the company’s dedication to Mazda’s unique Wankel rotary powerplants.
In an era dominated by piston engines, Amemiya-san saw the rotary engine’s potential. Compact, lightweight, and capable of producing impressive power outputs, the rotary engine had unique advantages, especially in the Mazda RX series. Amemiya sought to unlock the full capabilities of these engines through meticulous tuning, design innovation, and an unyielding passion for perfection.
The Rotary Engine: A Brief Overview
Before diving deeper into RE Amemiya’s accomplishments, understanding the rotary engine’s mechanics and appeal is essential.
1. **What is a Rotary Engine?**
Unlike traditional piston engines, rotary engines use a triangular rotor that spins within an oval chamber. This design allows for fewer moving parts, a smoother operation, and a higher power-to-weight ratio.
2. **Advantages of the Rotary Engine**
- Compact size
- High revving capability
- Smooth power delivery
- Lightweight design
3. **Challenges of the Rotary Engine**
Despite its advantages, the rotary engine faced challenges, including higher fuel consumption, emissions issues, and reliability concerns. However, these hurdles became opportunities for innovators like Amemiya to develop solutions and refine the engine’s performance.
