What Is The Function Of Flywheel?

The most important function of a flywheel on a car engine is to store and release rotational energy as the engine crankshaft rotates.

This allows the engine to run smoother then it would otherwise be.

Single cylinder engines have the greatest need for a flywheel as they in general have less rotating mass as well as longest time between power strokes. Multi cylinder engines can have progressively lower mass flywheels as they have greater rotational mass and more power strokes per rev.
