felülfutó

Felülfutó, also known as a supercharger, is a type of forced induction device used in internal combustion engines to increase the amount of air and fuel that can be drawn into the cylinders. This results in a higher power output and improved fuel efficiency. Superchargers are commonly used in high-performance vehicles, racing cars, and some modern production cars to enhance their performance.

There are two main types of superchargers: centrifugal and roots-type. Centrifugal superchargers use a rotating impeller to compress air, while roots-type superchargers use two intermeshing lobes to compress air. Both types work by drawing in air from the atmosphere and forcing it into the engine's intake manifold, where it is mixed with fuel and ignited.

Superchargers are typically driven by the engine's crankshaft through a belt or chain, but some systems use an electric motor to power the supercharger. This is known as a turbocharger, which uses a turbine to spin the compressor. Turbochargers are more common in modern engines due to their efficiency and reliability.

The use of superchargers in engines can lead to increased horsepower and torque, but it also requires careful management of boost pressure to prevent engine damage. Modern engines often use electronic controls to monitor and regulate boost pressure, ensuring optimal performance and longevity.
