It works under the engine for providing the spark to sparkplug timing.
It is different from the other ignition system in the contact breaker section.
Instead of the contact breaker, An armature is placed.
To burn the lean mixture in the combustion chamber electronic ignition system produces a stronger spark that is really great as compared to the Battery and Magneto ignition system.
Electronic Ignition System Definition:
As the name indicates “Electronic ” the system is fully controlled electronically and that is why we called it an Electronic ignition system.
Electronic Ignition System Parts:
An Electronic ignition system consists of the following parts:
- Ignition switch
- Electronic control module
- Ignition coil
Let’s understand one by one,
A battery is an electrochemical system, it stores energy and whenever require it gives.
Battery plays an important role here. It is having two terminals positive(+) and negative(-).
The positive terminal is connected to the key (Ignition switch). The negative terminal is connected to the ground.
It is connected just after Battery.
Ignition switch works like on and of the system. When it turns ON the power supplied from battery and when it is off, the power not supplying.
Electronic control module:
Here the work starts electronically. It is used to ON and OFF the primary current.
The ignition control module performs the same operation as that contact point performs in another ignition system.
It manages the dwell period (remains in a given state) on its own.
It plays an important role in generating the magnetic field. Here armature is used instead of contact breaker point in a conventional ignition system.
It is a pulse-type transformer, that is capable of producing short fire of high volt for beginning combustion.
It produces high voltage required to make pass the current in the gap at the spark plug.
An ignition coil is set of two sets of winding:
- Primary Winding (Outer winding).
- Secondary winding (Inner winding).
From the primary winding the current flows, Distributor controls on and of the cycle of the current flow.
The distributor makes spark occurs at each of the spark plugs and distributes high voltage to it.
It uses ignition coil high voltages to ignites the fuel.
Working Principle of Electronic Ignition System:
A battery plays an important role in supplying power. The negative terminal is grounded and a positive terminal is connected to the ignition switch.
Now when we turn on the ignition switch the power supply gets ON and further, the wire is connected to the electronic ignition module.
Here all the work will be controlled electronically.
From here it sends to the ignition coil. In Ignition coil there is two winding:
- Primary winding
- Secondary winding
Both winding are insulated and Primary are thicker than secondary winding. Now, there is one iron rod in between them that generates a magnetic field.
An armature is connected to the electronic module, the power comes and armature rotates.
Here you can see magnetic pick-up. When the magnetic pick-up and armature touches, the voltage signal generates.
and it generates further until a strong voltage signal comes. Here ON and OF process continues.
This voltage comes to the distributor section and here a rotor is connected. When the rotor rotates and touches the spark plug line it supplies the voltage and sparks plug ionized or we can say the distributor distributes the voltages.
Applications of Electronic Ignition System:
These are the applications of the Electronic Ignition System:
- This system used in aircraft engines.
- It also used in modern bikes and cars.
Advantages of Electronic Ignition System:
These are some advantages of Electronic Ignition System:
- It has fewer moving parts.
- Low maintenance required.
- Less emission generates.
- Efficiency is good.
- It also increases fuel efficiency.
Disadvantages of Electronic Ignition System:
Also, there are some disadvantages Electronic Ignition System and those are:
- The cost of this system is high it means expensive in cost.
So this is all about Electronic Ignition System, I hope you like this resource, feel free to comment down below your doubts or thoughts, I will happy to help you furthermore.
