What is the primary function of the flywheel in an engine system?

• A. Cooling the engine
• B. Storing rotational energy
• C. Fuel injection
• D. Exhaust management

Answer: (B)

The primary function of the flywheel in an engine system is to store rotational energy. When the engine operates, the flywheel maintains a consistent speed by storing energy during the power strokes and releasing it during the non-power strokes. This results in smoother engine operation and helps to reduce vibrations. By storing and releasing energy, the flywheel contributes to the overall efficiency of the engine, ensuring that power delivery is steady and responsive. Additionally, it plays a crucial role in matching the engine speed to the needs of the drivetrain, thereby improving performance and vehicle control.
