Understanding Your Car’s Ignition Coil: How It Works and When to Repair It
When things get out of date, there comes a time when it’s time to replace ’em. And this holds true whether it’s playground equipment at your local school, or worn ignition equipment in you car or truck. So, in this blog, the experts at Meineke in Hickory take a look at a particular and important part of your ignition system that may need attention as time wear on: your vehicle’s ignition coil.
What Is an Ignition Coil?
Your car’s ignition coil is an important part of your vehicle’s ignition system. Because, it’s responsible for generating the high-voltage spark needed to ignite the air-fuel mixture in your engine. And without it, your engine wouldn’t start or run efficiently.
The ignition coil is essentially a small transformer. And it converts the 12-volt power from your car’s battery into thousands of volts required to create a spark in the spark plugs. Furthermore, most modern vehicles have one coil per cylinder. Whereas, older models might have a single coil for all cylinders.
How Does It Work?
The ignition coil consists of two wire windings—a primary and a secondary coil. So, when the car’s computer signals, it interrupts the current in the primary coil. And this creates a magnetic field that induces high voltage in the secondary coil. This voltage is sent to the spark plugs, igniting the air-fuel mixture and powering the engine.
Signs Your Ignition Coil Needs Repair
A faulty ignition coil can lead to a range of performance issues, including:
- Engine Misfires: You may notice rough idling, hesitation, or a loss of power while driving.
- Difficulty Starting: A failing ignition coil can make it harder for your car to start, especially in cold weather.
- Poor Fuel Efficiency: Misfiring cylinders waste fuel, leading to more frequent stops at the gas pump.
- Check Engine Light: Ignition coil problems often trigger the engine’s diagnostic system, resulting in a warning light.
- Unusual Sounds: Clicking or sputtering noises could indicate a failing coil.
