Automobile English translation

I translated the following content by hand. I am a mechanical major, and now I am engaged in automobile marketing. I hope my translation can help you.

battery

Automobile battery, also known as lead-acid battery, is an electrochemical device that can generate voltage and current. In automobile batteries, we can use reversible electrochemical reaction to charge the battery, so that we can get a longer battery life. The function of the battery is to supply power to the starting motor and then excite the ignition system. In addition, when the energy output demand exceeds the upper limit of the alternator, the automobile battery can also provide additional power support for the system. In the automobile system, the battery plays the role of "electric energy storage".

Ignition latch

The ignition switch allows the driver to distribute current where it is needed. Generally speaking, there are five commonly used key positions.

1. Locking position

All circuits are disconnected (that is, no current flows) and the steering wheel is locked. In some cars, the gear lever cannot move in this position. If the steering wheel exerts force on the locking mechanism at this time, the key will be difficult to turn. If this happens, try turning the steering wheel, removing the torque, and then turning the key.

2. Closed position (closed)

All circuits are open, the steering wheel can be turned, but the key can't be taken out.

3. Run bit (run)

All circuits except the starting circuit are closed (that is, current is allowed to pass), and current will be delivered to all circuits except the starting circuit.

4. Start bit (start)

Only power is supplied to the ignition circuit and starter motor. This can explain why the car radio stops working when it is in the starting position. This position of the ignition switch is controlled by the load spring, so the starting motor does not work when the engine is running. This position is dynamic and instantaneous, just to activate the starting motor.

5. Annex

All circuits are energized except the ignition circuit and the starting motor. This position allows you to listen to the radio, use power windows, etc. when the engine is turned off.

Most ignition switches are mounted on the steering column, and some switches are divided into two independent parts:

A car lock used to insert and remove keys. The assembly also includes a mechanical structure for locking the steering wheel and the shift fork;

A switch that contains the actual circuit. It is usually installed at the top of the steering column, just behind the dashboard, and connected to the car lock through hinges or rods.
