What exactly is a flywheel?

What Is The Difference Between 153 and 168 Tooth Flywheel?

A flywheel, commonly crafted from cast iron, is a metal disc linked to one end of the crankshaft. Its role is to induce wheel rotation by engaging clutch discs. Cars employing manual transmissions typically incorporate a flywheel, while automatic transmissions utilize Flexiplates with a comparable function.

The flywheel needs to be durable since its teeth remain in constant contact with clutch discs, undergoing wear and tear. To address this, certain premium manufacturers now opt for carbon fiber flywheels, renowned as the toughest material known to humans.

Now, let’s delve into the key functions of the flywheel:

1: Effortless Engine Start

Contrary to common knowledge, the flywheel plays a pivotal role in initiating the engine, not just in propelling the wheels. It takes the form of a thick disc with gear teeth on its periphery. These teeth facilitate a connection with smaller gears attached to the starter motor, known as the Bendix gear.

Upon inserting the key, the Bendix gear and the flywheel engage, setting the gears in motion and initiating the flywheel and crankshaft. Once the compression is established, and the engine is running, the two disengage, allowing the flywheel to rotate freely.

The quality of the flywheel significantly impacts the speed and smoothness of the engine start. If you find yourself needing to turn the key multiple times for the engine to start, it might be due to a faulty flywheel with worn-out teeth edges.

2: Enhancing Drive Stability

The weight of the flywheel in your car is contingent on the crankshaft, and it plays a crucial role in optimizing engine cycles for a smoother driving experience. As the engine operates, the piston’s lateral movement generates significant vibrations, which, if unchecked, can disrupt the car’s balance.

By linking to the crankshaft, the flywheel mitigates unstable motion and dampens vibrations. If you sense unusual vibrations, especially at higher speeds, it’s advisable to have the flywheel inspected promptly.

3: Seamless Engine Revolution

Car engines operate as either 2-stroke or 4-stroke engines, producing power through two or four piston movements from one end to another. This inherently results in jerky motions. But why doesn’t the car feel this, and what sustains its movement between these piston firings?

The flywheel plays a crucial role in converting these piston revolutions into a continuous, smooth movement by contributing mass to preserve rotational inertia. Additionally, it aids the crankshaft in maintaining a consistent speed and motion, ensuring an overall smooth operation of the engine.
