Q

The purpose of the flywheel is to __________.

🔍 Key Concepts

• flywheel function in a diesel engine and how it relates to crankshaft rotation • difference between storing rotational energy vs. absorbing shocks or balancing forces • engine power stroke vs. non‑power strokes (intake, compression, exhaust)

💭 Think About

• Think about what happens to the crankshaft between power strokes in a multi‑cylinder engine. How does the engine keep turning smoothly when no cylinder is firing? • Which option describes a continuous role during every revolution of the crankshaft, rather than just at starting or at a specific speed? • Which choices describe functions usually handled by other components (like dampers, counterweights, or torsional vibration absorbers) instead of the flywheel?

✅ Before You Answer

• Identify which choice involves storing and releasing rotational energy over each cycle of the engine. • Eliminate any choices that only act during starting or at a single dangerous (critical) speed. • Consider which answer best explains why the flywheel is mounted on the crankshaft and has significant mass and inertia.
