Ignition Coils vs. Spark Plugs

July 18, 2020 Published by Leave your thoughts

Lots of people drive cars and operate vehicles, but there is still a lot of confusion out there among laypeople about how engines operate. Understanding more about the different components of engines can help you make sure you’re able to care for your vehicle as effectively as possible. Keep reading to learn about spark plugs versus ignition coils in Flagstaff, AZ. Learning more about these components is very helpful when it comes to vehicle maintenance and proper engine care.

What are ignition coils in Flagstaff, AZ?

Ignition coils are small components that are essential to the successful ignition of an engine. This coil is designed to transform low voltage from your vehicle’s battery into the volts necessary to create the spark that lights the engine and gets it running. While ignition coils are relatively small parts, they are specially designed with very precise specifications and features to ensure reliable performance. Here are some of the specific features of ignition coils:

  • Resistors: Ignition coils contain internal or external resistors or resistor wires that are designed to limit the current that flows from the vehicle’s battery. This is important for ensuring the proper current flow that’s necessary for reliable engine ignition.
  • High-voltage wire: Ignition coils have high-voltage wires that run from the ignition coil to the distributor and then from the distributor to each spark plug. Ignition coils use power transistors to maintain a consistent power supply.
  • Service detection: In most newer cars, ignition coils are connected to sensors that can trigger the check engine light in the event that the coil is faulty or damaged. This makes it easier for drivers to identify issues with vehicle ignition and invest in repairs before any further problems develop.

Spark plugs versus ignition coils in Flagstaff, AZ

A lot of people assume that spark plugs and ignition coils are the same thing, but these components are different. Ignition coils transmit voltage to spark plugs to create the spark that leads to the ignition of a vehicle. Each ignition coil powers one or two spark plugs, and there is typically one ignition coil for each engine cylinder in a vehicle.

Because ignition coils are such small, precise components, they can’t be repaired. Instead, faulty ignition coils must be replaced entirely to get them working again. If you notice that your check engine light has come on or there’s something wrong with the way your engine fires up, contact a mechanic as soon as possible. Get your system inspected to determine whether any part replacements are necessary to get your vehicle working properly again.
