Export flywheel

The flywheel, a disk-shaped part with a large moment of inertia, acts like an energy store. For a four-stroke engine, work is done once every four piston strokes, that is, only the work stroke is done, while the exhaust, intake and compression strokes all consume work. Therefore, the torque output to the external crankshaft changes periodically, and the crankshaft speed is also unstable. To improve this situation, a flywheel is installed at the rear end of the crankshaft.

function

At the power take-off end of the crankshaft, that is, the side that connects the gearbox and the work equipment. The main function of the flywheel is to store energy and inertia outside the power stroke of the engine. A four-stroke engine only does work in one stroke, and the energy for suction, compression and exhaust comes from the energy stored by the flywheel. The balance is corrected wrong, the balance of the engine mainly depends on the balance block on the shaft, the single-cylinder engine has a balance shaft.

The flywheel has a large moment of inertia. Since the work of each cylinder of the engine is not continuous, the engine speed also changes. When the engine speed increases, the kinetic energy of the flywheel increases, storing energy; When the engine speed decreases, the flywheel kinetic energy decreases, releasing energy. The flywheel can be used to reduce speed fluctuations during
