Today in this article, I'll show you the Definition, Components, Working Principle and also other important topics like Advantages, Disadvantages and Applications of Battery Ignition System. So let me first start with the definition.
What is Battery Ignition System?
Battery Ignition System is used in an automobile to produce a spark in the spark plug with the help of Battery. It is generally used in the 4-wheeler vehicle but nowadays it is also used in two-wheeler vehicle where 6-volt or 12-volt battery supplies the current to the ignition coil.
Parts of Battery Ignition System:
The main components of Battery Ignition system are listed below:
#1 Ignition Switch:
It is used for ON or OFF the engine. One end of the switch is connected with the Primary Winding of Ignition Coil via Ballast Resistor, and another end is connected with the Battery.
Basically when the key is put inside it and turned the switch in ON position then the circuit is completed (Close Circuit), and when moved towards the OFF position than its work as an open circuit. Nowadays, this switch is replaced by the Push Button, and this system is called a keyless system.
The battery is provided for supply the initial current to the ignition system more specifically ignition coil. Generally, the voltage of the battery is 6V or 12V or 24 V. In an automobile there are two types of Battery use widely, one is lead-acid battery and another one is the alkaline battery. Although there are Zinc Acid Battery and Lithium-Ion Battery is used in modern vehicles.
#3 Ignition coil:
It is the main junction or you can say the main part of Battery Ignition System. The main purpose of it is to step up battery voltage so that it is sufficient for generates the spark.
It is working as a step-up transformer, and have two winds, one is primary which have a lesser turn, and the other one is secondary which have a higher number of turn.
#4 Ballast resistor:
This is used to limit the current in the ignition circuit and generally made of Iron. It is placed in series between the Ignition Switch and Ignition Coil. However, it is used in old automobile vehicles.
#5 Contact Breaker:
The contact breaker is an electrical switch which is regulated by the cam and when the breaker is open, current flows through the condenser and charges it.
It is used in the multi-cylinder engine, and its purpose is to regulate spark in each spark plug at the correct sequence.
There are two types of distributors.
Carbon Brush Type
Carbon Brush Type:
It is consist of Carbon Brush which is slides over the metallic section embedded in the distributor cap.
In this type, the rotor arm is passed through the metallic section of the distributor cap but it does not touch the surface of the distributor cap. that's why it is called Gap Type Distributor.
A capacitor is a storing device where electrical energy is stored. It is fitted parallel to the contact breaker, when the current drops then it supplied the additional current so that the spark is produced. It is made of two metal plates separated by air or any other insulating material.
#8 Spark Plug:
Spark Plug is another important part of Battery Ignition system. Here the actual Spark is generated for the combustion of Fuel or Charge. If there is more then one spark plug exists then each one is connected separately with the distributor and gives the spark in the sequence.
Working Principle of Battery Ignition System:
In Battery Ignition System, when the Ignition Switch is turned on then the current will flows to the primary circuit through ballast register, primary winding and contact breaker
The flowing current induced a magnetic field around the primary winding, the more current we supply the more magnetic filed will generate. At a certain time, the contact breaker opens the current is flowing through the primary winding and fall. This sudden fall of current generates very high voltage around 300 V in the primary winding section.
Due to this immense amount of voltage the capacitor comes into the charging state when the capacitor charged fully then it starts delivering the current towards the battery, due to this reverse flowing of the current and already induced magnetic field in the primary winding, a very high voltage of 15000 V to 30000 V is generated in the secondary winding.
This high voltage current then transferred to the distributor via high tension cable, where already a rotor rotates inside the distributor cap and has metallic segments embedded on it. So when its start rotating then at a certain stage it opens the contact breaker point which allows the high voltage current to transferred to the spark plugs through the metallic segments.
So when the high voltage current reaches the spark plug then its generates a high intensity of spark inside the engine cylinder, which allows the combustion fuel to burn.
Advantages of Battery Ignition System:
These are the following advantages of Battery Ignition System:
The intensity of spark is good.
It can also provide a high concentration of spark even in low engine speed or starting of Engine.
The maintenance of this ignition system is very less compared to others.
Disadvantages of Battery Ignition System:
The disadvantages are:
Efficiency decreased with a reduction in spark intensity.
Occupies more space.
Efficiency decreased with a reduction in spark intensity.
Need periodic maintenance is needed for Battery only.
Applications of Battery Ignition System:
Here is the application of it:
Battery Ignition System is used in Automobile (Car, Bus, Truck even in the Bike) to produce the Spark so that Combustion fuel can be burned.
