Wiring Diagram For Ignition Coil - CentricPropaganda.Com

The ignition coil is an essential component of any internal combustion engine. It is the device that takes the 12-volt current from the car battery and converts it into the high voltage current required to ignite the fuel in the engine. Without it, your car won't start. But what is the purpose of an ignition coil? How does it work? And what are the signs of a faulty one?

The primary function of an ignition coil is to provide the high voltage current needed to ignite the fuel in the engine. This is done through the process of induction. The coil consists of two windings known as the primary winding and secondary winding. The primary winding receives the 12 volts from the car battery while the secondary winding is connected to the spark plug. When the primary winding is energized by the 12 volts, it creates a magnetic field which induces a higher voltage in the secondary winding. This induced voltage is what will ultimately be used to ignite the fuel in the engine.

The distributor is another important part of the ignition system. Its job is to control the timing of the ignition system. The distributor contains a rotating arm which is connected to both the ignition coil and the spark plugs. As the arm rotates, it switches between the primary and secondary windings, allowing for the high voltage to be delivered to the spark plugs at the right time. This ensures that the fuel is ignited at the correct time during the engine cycle.

The timing of the ignition system is critical as it has a direct effect on engine performance. If the timing is too far advanced, the engine will produce more power but at the expense of fuel efficiency. If the timing is too far retarded, the engine will run sluggish and can suffer from misfires. The distributor helps to ensure that the timing of the ignition system is correctly set.

Symptoms of a Faulty Ignition Coil

A faulty ignition coil can cause several symptoms, such as reduced engine power, poor fuel economy, and engine misfires. Other symptoms include backfiring, engine stuttering, rough idling, and a lack of acceleration. If you experience any of these symptoms, then it may be time to check your ignition system, including the coils.

You can test the ignition coil with a multimeter. This device measures the voltage output of the coil, which should be between 11,000 and 18,000 volts. If it is lower than this, then it is likely that the coil is faulty and needs to be replaced.

Replacing an Ignition Coil

If you suspect that your ignition coil is faulty, then it is important to replace it as soon as possible. Replacing the coil is a relatively straightforward process but should only be carried out when you are confident that you can do so safely. The first step is to remove the old coil using a wrench. Once the old coil is removed, you can then fit the new coil in its place.

It is important to note that ignition coils are vehicle specific. That is, they are designed for particular makes and models of cars. It is therefore important to ensure that the ignition coil you are purchasing is compatible with your vehicle. It is also recommended that you use original equipment manufacturer (OEM) parts where possible, as these will be better suited to your engine.

In conclusion, the ignition coil is a crucial component of any internal combustion engine. It converts the 12-volt current from the car battery into the high voltage current required to ignite the fuel in the engine. The primary and secondary windings of the coil create a magnetic field which induces the high voltage. The distributor controls the timing of the ignition system while the multimeter can be used to test the voltage output of the coil. Finally, it is important to remember that ignition coils are vehicle specific and should always be replaced with an OEM part.
