function
At the power output end of the crankshaft, that is, the side where the gearbox and the work equipment are connected. The main function of the flywheel is to store the energy and inertia outside the power stroke of the engine. The four-stroke engine only has one stroke of work to inhale, compress, and exhaust the energy from the energy stored in the flywheel. The balance is corrected. The balance of the engine mainly depends on removing the balance weight on the shaft. The single-cylinder engine has a special balance shaft.
The flywheel has a large moment of inertia. Since the work done by each cylinder of the engine is discontinuous, the engine speed also changes. When the engine speed increases, the kinetic energy of the flywheel increases to store energy; when the engine speed decreases, the kinetic energy of the flywheel decreases, releasing energy. The flywheel can be used to reduce speed fluctuations during engine operation.
In addition to the external output, the energy transmitted from the engine to the crankshaft during the work stroke also has part of the energy absorbed by the flywheel, so that the rotation speed of the crankshaft will not increase much. In the three strokes of exhaust, intake and compression, the flywheel releases its stored energy to compensate for the work consumed by these three strokes, so that the crankshaft speed will not decrease too much.
