What effect does the centrifugal impeller have on engine airflow?

• A. Converts air into static pressure
• B. Ignites the fuel/air mixture
• C. Compresses the air
• D. Cools the air

Answer: (C)

The centrifugal impeller plays a crucial role in the operation of a turbocharger or supercharger by compressing the air within the engine's intake system. As the impeller spins, it imparts kinetic energy to the incoming air, accelerating it outward and increasing its pressure. This process effectively densifies the air, allowing for a greater mass of air to enter the engine's combustion chamber. The result is improved combustion efficiency and an increase in overall engine performance. Understanding the importance of this compression is essential, as it directly influences the power output and efficiency of the engine, especially in high-performance applications. The other options do not accurately describe the primary function of the centrifugal impeller in this context and focus on different aspects of engine operation.
