How Battery Ignition System Works?

Battery Ignition System

Here you can get Battery Ignition System Working Principle. We’ll show you the Definition, Components, and also other important topics like Advantages, Disadvantages and Applications of Battery Ignition System.

Battery Ignition System is utilized in automobiles to produce spark in the spark plug for the combustion of fuel in the I.C. engine. Here the main source for the spark generation is the battery. It is in general utilized in light commercial vehicles.

Almost in each petrol engine, the want of spark is required to burn the gas in the Engine. And as a consequence an ignition system is always there in petrol or fuel engine for the spark generation. There are one of a kind ignition device which includes a magneto ignition system, distributorless ignition system and electronic ignition system.

What is Battery Ignition System?

A battery Ignition System is utilized in an vehicle to produce a spark in the spark plug with the assist of a Battery. It is generally used in the 4-wheeler automobile however these days it’s also utilized in two-wheeler cars in which a 6-volt or 12-volt battery components the present day to the ignition coil.

Working Of Battery Ignition System

  • In the Battery ignition system as the ignition switch is ON, the present day from the battery starts to flow through the primary circuit through ballast register, primary winding and contact breaker.
  • The present day flowing via the primary winding induces magnetic field around it. The greater might be the present day, the stronger will its
    magnetic field.
  • As the contact breaker opens, the present day via the primary winding collapse and this immediate collapse in the current induces a voltage of approximately 300V in the primary winding. This voltage induced in the winding charges the capacitor to the tons extra voltage than the battery. As the capacitor charged, the present day via the primary winding stops and the present day starts to waft to the battery form the capacitor. This reverses the direction of current and magnetic field in the primary winding. Due to the collapsing and reversing of the present day and magnetic field, a very high voltage of approximately 15000 to 30000 V induced withinside the secondary winding.
  • The excessive voltage current induced in the secondary winding is transferred to the distributor via a excessive tension cable.
  • The distributor has a rotor that rotates inside the distributor cap. The distributor cap has metal segments embedded into it. As the rotor rotates, it presses and opens the touch breaker point. This allows the excessive anxiety present day to switch to the spark plugs via the metallic segments.
  • As the excessive anxiety present day reaches the spark Plug, it produces spark in the engine cylinder for the combustion of the air-fuel mixture.

Parts of Battery Ignition System

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 every other stop is attached with the Battery.

Basically while the key’s positioned inner it and grew to become the switch in ON position then the circuit is completed (Close Circuit), and while moved closer to 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.

2 Battery

The battery is provided for supply the initial current to the ignition device greater specially ignition coil. Generally, the voltage of the battery is 6V or 12V or 24 V. In an vehicle there are kinds 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 utilized 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.

6 Distributor

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 – It is consist of Carbon Brush which is slides over the metallic section embedded in the distributor cap.
  • Gap Type – 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.

7 Capacitor

A capacitor is a storing device where electrical energy is stored. It is fitted parallel to the contact breaker, while the current drops then it supplied the extra current so that the spark is produced. It is product of metallic plates separated with the aid of using air or every other insulating material.

8 Spark Plug

Spark Plug is every other critical a part of Battery Ignition system. Here the actual Spark is generated for the combustion of Fuel or Charge. If there may be greater then one spark plug exists then every one is connected one at a time with the distributor and offers the spark in the sequence.

Advantages of Battery Ignition System

These are the following advantages of Battery Ignition System:

  • The intensity of spark is good.
  • It also can offer a excessive concentration of spark even in low engine speed or starting of Engine.
  • The maintenance of this ignition system is very much less as compared to others.

Disadvantages of Battery Ignition System

  • In the battery ignition system, the battery is necessary for the ignition. It becomes difficult to start the engine when the battery is discharged.
  • Occupies huge space
  • The performance of the system decreases because the engine speed increases.
  • Since the breaker contact points are continuously subjected to mechanical in addition to electric put on which leads to quick maintenance intervals.

Applications of Battery Ignition System

Here is the application of it:

  • Battery Ignition System is used in Automobile (Truck, Car, Bus even in the Bike) to produce the Spark so that Combustion fuel can be burned.
