What Is Ignition Coil
The part that aids in starting an automobile’s engine, the car ignition coil, is sometimes referred to as a spark coil. It is an essential element of the ignition system. Your ignition system includes the switch battery, alternator, spark plugs, distributor, and ignition coil. Either the coil physically rests on top of the spark plug or is wirelessly connected to the spark plug.
How Does It Work?
A car’s battery only has 12 volts, but thousands of volts are required to fire the spark plug. The ignition coil, essentially a small electric transformer, amplifies the 12 volts from the automobile battery to the necessary thousands of volts. Two windings are around an iron core in the ignition coil, usually submerged in oil to keep the component cool. When the coil is powered up, the charge is pushed into the outer coil, generating a magnetic field. When turned off, the field drops, sending the charge to the inner coil, which is coiled more tightly, where it is then transformed into the extremely high voltages necessary to generate the sparks required to ignite the fuel in the pistons. The ignition coil’s energy is needed for the spark plug to produce the spark sufficient for burning. Your car won’t start at all if there isn’t combustion. For combustion to occur, a spark must ignite the fuel mixture in the engine.
Types of Ignition Coils
When attempting to fix an ignition coil issue, you should be aware of the many types of ignition coils.
- Coil-On-Plug (COP)
- Coil-Near-Plug (CNP)
- Coil-Per-Cylinder (CPC)
Coil-On-Plug is the most popular system, which utilizes numerous coils (COP). Each cylinder has a single ignition coil linked to a spark plug. You might have a CNP configuration if there isn’t enough area for a COP, perhaps because the spark plugs stick out from the cylinder head. In this instance, short plug wires would be used to connect the coils to the plug.
Signs Your Ignition Coil Has A Problem
1.Car Won’t Start
It could be difficult to start if your car has just one ignition coil. If the battery is fully charged, yet all you seem to hear when you turn the key or press the button is a clicking noise, you may have an issue with the ignition coil. The engine will not start properly if the spark plugs do not receive the needed charge.
2.Engine Stalling and Misfiring
Strange noises and a slow reaction from the engine, which causes jerks or vibration when the engine is idle, can be warning signals that the ignition coil is about to malfunction. In the worst-case scenario, this can cause the automobile to shut off and stall when you press the gas completely.
Heat dissipation results from the ignition coil’s enormous current and charge transformations. The oil often aids in dispersing this heat energy when the component operates correctly. However, if the coil is damaged, this can result in overheating, which can eventually cause the enclosure to fracture and the oil to start leaking from the component.
