Ignition coils are an essential component in your vehicle’s ignition system, converting the vehicle’s battery voltage into the thousands of volts needed to create an electric spark in the spark plugs. This spark is what ignites the fuel-air mixture in the cylinders, ultimately powering your car. Understanding how ignition coils work and how to maintain them can help ensure your vehicle runs smoothly and efficiently.
Understanding Ignition Coils
At its core, an ignition coil functions as a sort of electrical transformer. It takes the 12-volt power from your vehicle’s battery and transforms it into 25,000 volts or more. This high voltage is essential to bridge the spark plug gap and ignite the fuel. Ignition coils come in various designs but generally fall into three categories: canister, coil-on-plug, and distributor.
The Types of Ignition Coils
-
Canister Coils: These are one of the most traditional types and are typically used in older vehicles. They consist of a cylindrical housing that contains the primary and secondary windings. Mounted externally on the engine, these coils work with a distributor to deliver spark.
-
Coil-On-Plug: This modern design places the ignition coil directly over each spark plug, eliminating the need for spark plug wires. This layout is efficient as it reduces the transmission loss of voltage and the risk of radio frequency interference.
- Distributor Coils: Found in distributor ignition systems, these coils deliver high voltage to the distributor, which then routes the voltage to the spark plugs via spark plug wires.
Common Issues and Symptoms
Ignition coils can fail over time, often leading to engine misfires, a decrease in power, poor fuel economy, and even engine stalling. Here are some common symptoms of a failing ignition coil:
-
Engine Misfire: The most common sign of a faulty ignition coil is engine misfire. Since the coil is responsible for generating the spark that ignites the air-fuel mixture in the engine, a faulty coil can lead to incomplete combustion and a rough idle.
-
Check Engine Light: Modern vehicles are equipped with onboard diagnostic systems that can detect issues with ignition coils. If the check engine light turns on, a diagnostic scan can reveal a coil malfunction.
- Reduced Fuel Efficiency: If the ignition coil is not providing the spark needed for optimal combustion, the engine may burn more fuel than necessary, reducing mileage.
Maintenance Tips
Routine Inspection
One of the best ways to ensure your ignition coils are functioning properly is to inspect them regularly. Look for any signs of wear or damage, such as cracks or corrosion. It’s also advisable to check the electrical connections and ensure there’s no buildup of dirt or grime.
Quality Replacement Parts
When the time comes to replace your ignition coils, opting for high-quality parts can make a significant difference. At Patrick Derek Fletcher, we offer a range of high-performance ignition coils designed to meet or exceed OEM specifications, ensuring reliability and longevity.
Professional Assistance
While some automotive enthusiasts prefer DIY maintenance, when it comes to complex components like ignition coils, professional assistance is often the best route. A certified mechanic can provide a thorough diagnosis and replacement, ensuring your vehicle’s ignition system remains in top condition.
In summary, spark up your knowledge about ignition coils, keep a routine check, and only use quality parts to avoid unexpected breakdowns and ensure your vehicle runs efficiently.
