Honda Civic Ignition Coil

The ignition coil are the part of the engine mechanism that helps in the ignition. It is also referred to as a spark coil, and is basically an induction coil. Its job is to transform the low voltage of the battery into the thousands of Volta that are actually needed to create an electric spark in the spark plugs. This then helps fuel ignition by the spark plugs. In short, it can lead to stalling and starting issues in your vehicle.

The ignition coils, also known as the spark coils are an induction coil in the ignition system of an automobile that are responsible for transforming the low voltage of the battery into the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel.

The working of the ignition coils can be explained as follows: Whenever you turn on the ignition switch on your vehicle, the current passes through the primary winding responsible for creating a magnetic field in and around the iron core. The primary current collapses, as contact breaks in the touch breaker. This breaks down the magnetic field in the heart, too. This sudden magnetic field breakage induces a very high voltage across the secondary winding. The voltage generated amounts to around 50000 Volts. Now, this high voltage flows through the ignition distributor to the spark plug to provide spark for ignition.

It might come to you as a surprise that not all cars are fitted with ignition coils but those that do all have them in the same place i.e. next to the spark plugs on the right hand side of the engine.
