What parts does the traditional ignition system consist of? What are their respective roles?

The traditional ignition system is mainly composed of power supply (energy storage, generator), ignition switch, ignition coil, distributor, spark plug, high voltage conductor and so on.

1. power supply: the function of power supply in the ignition system is to provide it with the energy needed for work.

2. Ignition switch: The ignition switch is used to control the on-off of the instrument circuit, the primary circuit of the ignition system and the starter relay circuit.

3. Ignition coil: The main function of the ignition coil is to convert low-voltage DC into high-voltage DC.

4. Distributor: The distributor consists of circuit breaker, distributor, capacitor and ignition advance adjusting device. The main function of the distributor is to distribute the high-voltage electricity generated by the ignition coil to the spark plugs of the corresponding cylinders according to the ignition time and ignition sequence required by the engine.

5. Spark plug: The high-voltage electricity distributed by the distributor is introduced into the combustion chamber to ignite the combustible mixture in the combustion chamber.

6. High voltage conductor: reliable transmission of various voltages in the ignition system.

Extended data:

First, the shortcomings of the traditional ignition system:

1, contact ablation and wear caused by mechanical contact, etc. Avoid frequent replacement, adjust the closing angle and correct the ignition timing.

2. It can't control the on-off of the primary current of the ignition coil, nor can it amplify and process the pulse signal sent by the sensor. In addition to the switch function, the ignition controller can also know the engine speed according to the pulse step and provide the change of ignition time with the speed.

Second, the advantages of traditional ignition system:

The traditional ignition system is simple in structure and low in cost, and it is an earlier and more common ignition system.
