Flywheel

Flywheel, a disk-shaped part with a large moment of inertia that acts as an energy store. For a four-stroke engine, work is done once every four piston strokes, that is, only the work stroke does work, and the three strokes of exhaust, intake and compression consume work.

    Flywheel, a disk-shaped part with a large moment of inertia that acts as an energy store. For a four-stroke engine, work is done once every four piston strokes, that is, only the work stroke does work, and the three strokes of exhaust, intake and compression consume work.

    Flywheel 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 engine's power stroke. A four-stroke engine only does work for one stroke. The energy of intake, compression, and exhaust comes from the energy stored in the flywheel.

    The flywheel has a large moment of inertia. Since the work of each cylinder of the engine is discontinuous, 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 kinetic energy of the flywheel decreases, releasing the energy. The flywheel can be used to reduce speed fluctuations during engine operation.

    Installed at the rear end of the crankshaft of the engine, it has rotational inertia. Its function is to store the energy of the engine, overcome the resistance of other components, and make the crankshaft rotate evenly; through the clutch installed on the flywheel, the engine and the car transmission are connected; The engine is engaged to facilitate the engine start. And it is the integration of crankshaft position sensing and vehicle speed sensing.

    In addition to the external output, part of the energy transmitted by the engine to the crankshaft during the work stroke is absorbed by the flywheel, so that the speed of the crankshaft will not increase much. In the three strokes of exhaust, intake and compression, the flywheel discharges its stored energy to compensate for the work consumed in these three strokes, so that the crankshaft speed does not decrease too much.

    In addition, the flywheel has the following functions: the flywheel is the active part of the friction clutch; the flywheel ring gear for starting the engine is inlaid on the flywheel rim; the flywheel is also engraved with a top dead center mark to calibrate Ignition timing or fuel injection timing, and adjust valve clearance.
