1. As a kinetic energy storage, adjust the change of crankshaft speed to stabilize the speed.
2. The output of the engine speed and torque can make the output speed and torque of the engine more uniform and stable.
3. Reduce the vibration caused by the rotation of the engine and reduce the load on the transmission to avoid overload operation.
4. The starter torque can be transmitted to the engine, so we can start the engine better.
5. Pass the output crankshaft speed signal to the sensor.
