What are the components of the starting system?

[Howard]

The starting system consists of the car battery, ignition switch, starting relay, starter motor, and fuse. The main function of the car's starting system is to convert the electrical energy from the battery into mechanical energy to start the vehicle. The starter motor is primarily activated by an external force. The working principle of the starting system is as follows: when the starting switch is turned on, the starter circuit is energized, and the relay's pull-in coil and hold-in coil are also energized, generating a strong magnetic force to attract the iron core to move leftward. This action drives the drive lever to rotate around its pivot, causing the gear to engage with the flywheel ring gear. Simultaneously, as the current from the pull-in coil passes through the motor's windings, the armature begins to rotate, and the gear moves out while rotating, reducing impact.
