Working Of Battery Ignition System
In the Battery ignition system as the ignition switch is ON, the current from the battery starts to flow through the primary circuit through ballast register, primary winding and contact breaker.
The current flowing through the primary winding induces magnetic field around it. The more will be the current, the stronger will its magnetic field.
As the contact breaker opens, the current through the primary winding collapse and this immediate collapse in the current induces a voltage of about 300V in the primary winding. This voltage induced in the winding charges the capacitor to the much greater voltage than the battery. As the capacitor charged, the current through the primary winding stops and the current starts to flow 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 current and magnetic field, a very high voltage of about 15000 to 30000 V induced in the secondary winding.
The high voltage current induced in the secondary winding is transferred to the distributor through a high tension cable.
The distributor has a rotor that rotates inside the distributor cap. The distributor cap has metallic segments embedded into it. As the rotor rotates, it presses and opens the contact breaker point. This allows the high tension current to transfer to the spark plugs through the metallic segments.
As the high tension current reaches the spark Plug, it produces spark in the engine cylinder for the combustion of the air-fuel mixture.
