Automobile Engineering

1. When the ignition switch is turned on, the current flows from the battery through the primary winding, ballast register and contact breaker.
2. The flowing current induces a magnetic field directly proportional to it.
3. As the contact breaker opens, the current collapses resulting in high voltage induction in the secondary winding.
4. The high voltage current generated in the secondary winding is transferred to the distributor via a cable with high tension.
5. The distributor consists of a rotor that rotates inside the distributor cap and opens the contact breaker point. This causes the high tension current to flow to the spark plug.
6. A spark is generated in the engine cylinder by the current upon reaching the spark plug which facilitates the combustion of fuel and air.
