The ignition system work with the combination of condenser and ignition coil. The main purpose of this system is the creation of a spark. Hence further this spark is used to ignite the fuel-air mixture in a cylinder of the engine. Moreover, due to the high temperature, the ignition system passes the high voltage to spark which is a spot at the top of compression stroke. Talking about the applications of this system, one can easily observe it in spark ignition internal combustion engines as well as in petrol road vehicles. For example, it is further useful in automobile industries.

Working on ignition system by connecting it with different parts:

Ignition system works with battery, ignition switch, condenser, ignition coil and spark plugs.

ignition system

Battery:

Thus the battery is position as a source of low and high voltage system. The negative or you can say secondary wiring is for grounding. Hence now the positive or primary wiring is a position with as a connection of ignition switch.

Ignition switch:

Two circuits are there in ignition switch one of them is to send the battery voltage to the coil. The second one is for  the primary resistor which is applicable for step down the voltage.

Working:

The battery place in it is applicable for passing the voltage through primary wiring to the ignition switch. The switch further contains two separate terminals one is valid for passing the currents to ignition coil through positive wiring.

Thus another one is applicable for passage of resistance. Now the process starts when the ignition switch is ON for the passage of current through it. The current takes place through the battery to the ignition coil.

Now ignition coil starts its process with the involvement of primary as well as secondary winding. The current flows through twist turns of the primary winding.

The passage of current through the coil is directly sent to contact breaker. Hence one terminal is put together with a condenser which is responsible for reducing the burning points and absorbing the back EMF.

The camshaft of ignition system performs the operation of open as well as closes the contact breaker. Cam lobe is put in the center which pushes the contact breaker and through its opening the current from primary circuit breaks. Due to breakage, an EMF is induced to increase the primary winding of ignition coil therefore which increases battery’s 12 volts to 22,000 volts.

High voltage is then bypass to the distributor, according to ignition timing the rotor will rotate inside the distributor. Though due to air gap the voltage jumps. Thus high tension cables transfer high voltage from the distributor to spark terminals. In next process, the voltage continues to the central electrode to which is further close by an insulator. Thus ionization conditions occur by exceeding in voltage. Therefore the spark is finally produced by allowing the current to flow through the gap.
