Background
The flywheel is a disc-shaped component with a large moment of inertia. For a four-stroke engine, work is done every four piston strokes, i.e. only the work stroke works, and the three strokes of exhaust, intake and compression all consume work. Therefore, the torque output by the crankshaft is periodically changed, and the rotating speed of the crankshaft is unstable. In order to improve the condition, a flywheel is arranged at the rear end of the crankshaft, and the flywheel is used for storing energy of the engine and overcoming the resistance of other components so as to enable the crankshaft to rotate uniformly.
