What provides airflow through the engine?

• A. Main compressor
• B. Fuel pump
• C. Spark plugs
• D. Exhaust

Answer: (A)

Airflow through the engine is provided by the compressor stage, which draws in air from the inlet and compresses it so a steady flow of high-pressure air moves toward the combustion chamber. This compression is essential for efficient combustion and is driven by the turbine that the engine uses to power the compressor. The other components have different roles: the fuel pump introduces fuel for burning, spark plugs ignite the fuel–air mixture in ignition systems, and the exhaust serves as the outlet for combustion gases. So the main compressor is the part that creates and maintains the airflow through the engine.
