What Does The Flywheel Do?

Have you ever wondered about the mysterious disk-like component nestled between the engine and the transmission in your vehicle? 

That's the flywheel, a crucial yet often overlooked part of the drivetrain system, and in this blog, we'll get to know it and what it does. Understanding the role of the flywheel will help you appreciate its contribution to smooth engine operation and efficient power transfer. So, let's unravel the mysteries surrounding the flywheel and explore its vital functions.


 What Is Its Main Function? 

The main function of the flywheel is to store and transmit rotational energy generated by the engine to the transmission and, ultimately. to the wheels. It acts as a mechanical energy reservoir, enabling a smooth and continuous power transfer from the engine to the drivetrain.


 What Else Does It Contribute To? 

Starting The Engine
In vehicles with manual transmissions, the flywheel plays a crucial role in starting the engine. The flywheel is connected to the engine's crankshaft and provides the necessary momentum for the engine to begin rotating when the starter motor engages. The flywheel's weight and rotational energy help overcome the engine's initial inertia and kickstart the combustion process.

Reducing Vibrations
Another essential function of the flywheel is to reduce variations caused by each power stroke during combustion. The rotational mass of the flywheel evens out these fluctuations, resulting in smoother power delivery and preventing stalling or jerky movements of the vehicle. The flywheel also serves as a vibration damper, reducing engine vibrations caused by the reciprocating motion of the pistons. By absorbing and dissipating these vibrations, the flywheel helps maintain engine stability, reduces stress on engine components, and enhances overall comfort and durability.

Contains The Clutch Assembly
For vehicles with manual transmissions, the flywheel houses the clutch assembly. The clutch disc is pressed against the flywheel's surface to engage or disengage the transmission from the engine. The flywheel's smooth and flat surface provides the necessary friction for the clutch to engage securely, allowing for seamless gear shifting.
