The ignition coil is an invention older than the internal combustion engine, which has survived to this day in practically unchanged form. It is an element of the ignition system in petrol-powered cars. The car coil is responsible for accumulating enough energy to produce a spark through the spark plug and, as a result, starting the vehicle.
Principle of operation of ignition coil in car
The starter coil converts low voltage current into high voltage current. The car coil consists of two electrical windings, primary and secondary, which are wound on an iron core. The coil in the car uses the laws of electromagnetism. When the current reaches the primary winding from the battery, an electromagnetic field is created inside the coil. Then the ignition system closes the circuit with an electric charge, which results in induction. The collapse of the magnetic field produces a current that has a voltage of about 250 to 400 V, which then goes to the primary winding, where it is multiplied even a hundred times. The voltage at this level causes the spark plug to give a spark, igniting the fuel-air mixture.
