Understanding 4 Rotor Engines
4 rotor engines are unique to the rotary engine family, utilizing four rotors to achieve greater power and efficiency compared to their 2 rotor and 3 rotor counterparts. The architecture allows for a compact design while delivering substantial horsepower, making them popular in racing and high-performance applications.
Design and Mechanics
Rotary engines differ from traditional piston engines in their operation and design. The 4 rotor configuration allows for increased displacement and power output without significantly increasing the engine’s physical size. Key components include:
- Rotors: The heart of the engine, typically made from lightweight materials for improved performance.
- Side Housings: These contain the rotors and are meticulously machined to ensure precision.
- Apex Seals: Vital for maintaining compression, these seals are often upgraded to ceramic for enhanced performance.
Applications
4 rotor engines are versatile and can be used in various applications including:
- Street Use: Engine configurations that balance performance with drivability, such as those offered by Pettit Racing.
- Circuit Racing: High-performance builds designed for track use, focusing on maximum power and responsiveness, like those from Defined Autoworks.
- Custom Builds: Tailored engines for specific racing needs, allowing for extensive modifications.
