How engine works? Explain the function of flywheel? What if we use a flywheel of smaller size?

Question

Accepted Answer

The flywheel is a mechanical device that stores rotational energy and helps in maintaining the engine's speed and stability.

The flywheel is connected to the crankshaft of the engine and stores excess energy during the power stroke.
During the compression stroke, the stored energy in the flywheel helps in maintaining the engine's momentum and smooth operation.
The flywheel also acts as a rotational inertia, reducing speed fluctuations and providing a consistent power output.
A smaller flywheel would have less rotational inertia, resulting in faster speed fluctuations and reduced stability.
Using a smaller flywheel may lead to increased vibrations, decreased torque, and potential damage to the engine.
