what is flywheel in car

A flywheel in a car is a heavy disc attached to the end of the engines crankshaft. It serves several important functions within the engine setup. The primary purpose of a flywheel is to provide mass for rotational inertia, which helps to keep the cars engine running smoothly. Additionally, the flywheel balances the engine and allows for an electric starter. It is also crucial for connecting the engine with the transmission via a clutch. In a manual transmission, the flywheel is a vital component that plays a key role in the operation of the vehicle. It is firmly bolted to a flange on the transmission side of the crankshaft inside the bell housing and has gear teeth that engage with the engines starter motor. The flywheel is specifically weighted to the cars crankshaft to smooth out the rough feeling caused by even a slight imbalance. Overall, the flywheel is essential for the proper functioning and performance of a cars engine.
