Explanation: 

Flywheel:

  • The flywheel stores energy during the power stroke and supplies it to the crankshaft during the idling stroke i.e. suction, compression, and exhaust.
  • In many engines, the flywheel also serves as a mounting surface for the clutch.
Construction:
  • The flywheel is attached to the rear end of the crankshaft by means of bolts.
  • A large ring gear is attached to the flywheel.
  • While starting, the engine starter motor’s gear engages with the ring gear, and the flywheel rotates to crank the engine.
  • When an automatic transmission is used the torque converter assembly acts as the flywheel.
  • The flywheel also serves as a mounting and frictional surface for the clutch assembly.
  • The size of the flywheel depends upon the number of cylinders and the general construction of the engine.

Clutch:

  • A clutch is used to connect and disconnect the transmission of power from the engine flywheel to the transmission gearbox of the drive shaft.
