A simple guide on how does a car ignition coil work?

The ignition coil is one of the most critical aspects of a car’s ignition system. It would be impossible to provide the charge to the spark plugs without the ignition coil. This may lead to engine misfires, poor acceleration, and rough handling. It can even be difficult to get started on your engine. Replacing a faulty ignition coil can help address these issues. Learning how to displace ignition coil is not hard enough that you is capable of doing it on your own. The ignition coil on car is supposed to last around 100,000 miles or even more. You will have reduced gas mileage when coil begins going bad and becomes less in a position to transfer power. Your car requires more fuel to run; this means you will spend more money on gas than normal.

A sputtering or jerking motion of the automobile is a sign of engine misfiring. What causes misfiring could be faulty spark plugs or wires, bad fuel injector. Even transmission or mechanical problems and an imbalance in the air/fuel ratio could be reasons for misfires. Also you can check engine misfire codes to help you locating the causes. As car is idling or low-speed, this might feel just like engine shaking or a random, but repeated loss of power because coils send irregular electrical currents to the spark plug. If your automobile has become difficult to start, replacing the ignition coil may be considered a solution to your problem.

If you’re having trouble with your car, the problems may be due to a bad ignition coil. An ignition coil is the part of your automobile that transforms the power from the battery to a higher voltage to ignite the air-fuel mixture in the cylinder. Maybe you are having a hard time starting your vehicle, or your automobile is losing power while you are on the road.

How does a car Ignition Coil Work?

The ignition coil is part of the ignition system of a car. The ignition system involves the ignition switch battery, the alternator, the ignition coil, the spark plug, and the distributor. The ignition coil does the most crucial job, which is transforming the low-tension current of the battery to high-tension current. The average car runs on the 12V battery, and the spark plugs need about 20,000 to 40,000 volts to ignite the fuel. This is the reason the ignition coil is generally known as a compact transformer.

The ignition coil has two windings wrapped around an iron core. Normally, the coils are inside a housing filled up with oil to act as a refrigerant. The primary winding is the one with the low-tension current which is the outer coil. The secondary winding has a lot more turns of wire than the primary winding which is the one that transmits the high-tension current. This configuration makes the ignition coil a step-up transformer.

When the 12V current enters the primary coil, it generates an electromagnetic field. Then current suddenly stops, and the magnetic field collapses quickly. This event induces a high-voltage current on the secondary coil, which is delivered to the spark plug or the distributor, with regards to the configuration.
