The compressed air from the turbocharger allows the engine to burn more fuel, resulting in increased power output. Similar to supercharger rotors, turbocharger rotors also have a direct impact on engine power based on their rotation speed.
The relationship between the number of rotors and boost pressure
The number of rotors in a supercharger or turbocharger system can significantly influence the boost pressure generated in the engine. Boost pressure refers to the increase in air pressure delivered to the engine’s intake manifold compared to atmospheric pressure.
In general, the more rotors a supercharger or turbocharger system has, the higher the boost pressure it can produce. This is because each rotor adds another stage of compression, resulting in greater air compression and higher boost pressure.
For example, a single-rotor supercharger or turbocharger system will typically generate less boost pressure compared to a twin-rotor or twin-turbo system. The additional rotors provide more opportunities for air compression, resulting in increased boost pressure and engine power.
However, it is essential to strike a balance between boost pressure and the engine’s capability to handle it. Excessive boost pressure can put excessive strain on the engine’s internal components and may require additional modifications to maintain reliability. Therefore, the number of rotors should be chosen according to the engine’s design and intended application to achieve optimal performance without compromising durability.
