All that momentum spinning around and around makes the engine run smoother.
Take this as an example:
On the old fashoined printing press machines you had to press a pedal down again and again to run the machine. There was a big heavy flywheel to keep the momentum there while you brought your foot back up to keep it running nicely.
Same concept applies to an engine. Between fires, explosions, strokes, bangs, when the fuels combusts-whatever you want to call it, that inertia/momentum in the flywheel keeps everything spinning/running until the the piston reaches the top again to explode the fuel.
Make sense?
