The ignition system circuit is a system that supports the combustion system in the combustion chamber through an intermediate spark plug. The spark from the spark plug is the final part of the ignition system process. The ignition system has several systems. One of them is a conventional / platinum ignition system.
However, conventional ignition systems are no longer used, replaced by CDI ignition systems. However, the CDI ignition system has now shifted to the ECU / ECM system. Although conventional ignition systems are no longer used / produced. But there is nothing wrong for you to find out a little information about conventional ignition systems. For information this time, I want to inform you about the components of a conventional ignition system.
Components of Conventional Ignition Systems + Functions
There are 5 main components of a conventional (platinum) ignition system, including:
- Battery
- Ignition Key
- Ignition Coil / Ignition Coil
- Distributor
- Spark plug
The following is an explanation of the functions of kompone - these components.
1. Battery / battery
conventional ignition system components
Battery / battery / battery is a source of electrical energy. And, it functions to store electricity.
2. Ignition key
The ignition key is to disconnect and connect electricity to the circuit or turn off and turn on the system. The ignition key on a vehicle has 3 or more terminals.
The main terminal on the contact is terminal B or AM connected to the battery, the IG Terminal is connected to (+) the ignition coil and other loads that are needed, the ST terminal is connected to the selenoid starter. If the ignition has 4 terminals then the 4th terminal is the ACC terminal which is connected to the accesoris of the vehicle, such as: radio, tape and others.
3. Ignition coil
Ignition coil functions as a step up transformer, which is raising the voltage from the 12 Volt battery voltage to a high voltage of more than 15,000 Volt. Ignition coil consists of: soft iron core, coil primer, coil secondary, coil house and coil terminal.
4. Distributor
The distributor functions to distribute the secondary high voltage induction coil to the spark plug according to the ignition order of the motor or FO (firing order).
Distributor is the place for most ignition systems. Components available at the distributor include: platinum (contact breaker), condenser, contact breaker, centrifugal advancer, vacum advancer, rotor distributor and distributor cap.
5. Spark plugs
The spark plug serves to sprinkle the sparks to burn the fuel mixture in the combustion chamber when it is fed by high voltage electricity. Sparks occur in the gap between the middle electrode and the mass electrode, the spark occurs due to the jump of high voltage current from the middle electrode to the mass electrode.
6. High voltage cable
The high-voltage cable serves to channel high-voltage electric current from the secondary induction coil to the spark plug. The voltage supplied is 15,000 volts to 30,000 volts.
The high voltage cable consists of copper which is isolated with silicone rubber, because the current that flows the voltage is very high, the insulator is very thick.
Thus the article about conventional ignition system components, hopefully adds a little insight and is useful.
