If you’re a car enthusiast, you probably know that the ignition system plays a crucial role in starting and running your vehicle. One of the key components in the ignition system is the ignition coil. In this article, we’ll be discussing the 4 wire ignition coil diagram and how it works.
What is an Ignition Coil?
An ignition coil is an electromagnetic device that converts the low voltage from the battery to high voltage needed by the spark plugs. It is responsible for generating the spark that ignites the fuel in the combustion chamber.
What is a 4 Wire Ignition Coil?
A 4 wire ignition coil, also known as a waste spark ignition coil, is a type of coil that is commonly used in modern vehicles. It has four wires that connect to the primary and secondary winding, as well as the power and ground wires.
How Does a 4 Wire Ignition Coil Diagram Work?
The 4 wire ignition coil diagram consists of two primary windings and two secondary windings. The primary windings are connected in series and receive power from the battery. When the ignition switch is turned on, current flows through the primary windings, creating a magnetic field. The magnetic field then collapses, which induces a high voltage in the secondary windings. This high voltage is then sent to the spark plugs, which ignite the fuel in the combustion chamber.
Advantages of a 4 Wire Ignition Coil
One of the advantages of a 4 wire ignition coil is that it is more efficient than a traditional coil. This is because it uses a waste spark system, which means that each coil fires two spark plugs at the same time, one for the compression stroke and one for the exhaust stroke. Another advantage is that it is more reliable and durable since it operates at a lower temperature compared to traditional coils.
Common Issues with a 4 Wire Ignition Coil
Like any other component in a vehicle, a 4 wire ignition coil can also experience issues. Some of the common issues include misfires, which can be caused by a faulty coil, spark plugs, or wiring. Other issues include a weak or no spark, which can be caused by a damaged or worn-out coil.
In conclusion, a 4 wire ignition coil is an essential component in the ignition system of modern vehicles. It is efficient, reliable, and durable, making it a popular choice among car manufacturers. By understanding how it works and the common issues that can arise, you can better maintain your vehicle and avoid costly repairs.
