In a supercharger, how does the mixture move through the system?

In a supercharger, the correct understanding of the airflow through the system involves recognizing the function of the impeller within the compressor section. The mixture enters through the eye of the impeller, which is the central part of the rotating component. As the impeller spins, it effectively accelerates the mixture outward towards the periphery, where the increased velocity translates into increased pressure.

This design allows the supercharger to efficiently compress the air-fuel mixture as it is drawn in, creating the higher density required for enhanced engine performance. The movement from the eye to the periphery is crucial because it maximizes the energy imparted to the mixture, which is essential for the supercharging process. Thus, the proper flow direction in a typical supercharger system is characterized by the entry of the mixture at the eye and its exit at the periphery.
