Dive into Ignition Control Modules: ACDelco vs. Delphi

When it comes to the performance of your vehicle, the ignition control module plays a crucial role. Responsible for ensuring the proper functioning of the ignition system, the ignition control module works in conjunction with the ignition coil to provide the necessary spark to ignite the fuel-air mixture in the engine cylinders. In this article, we will take a deep dive into the world of ignition control modules, specifically comparing two leading brands – ACDelco and Delphi. Through an in-depth analysis of their features, benefits, price, and performance, we aim to help you choose the right ignition control module for your vehicle.

What are Ignition Control Modules and How Do They Work?

Ignition control modules, also known as ignition control units, are electronic devices that regulate the timing and intensity of the spark produced by the ignition system. They control the firing of the spark plugs, ensuring they fire at the correct time to optimize engine performance. The ignition control module receives signals from various sensors in the engine, such as the crankshaft position sensor and the camshaft position sensor, to determine the precise timing of the spark.

Furthermore, ignition control modules are responsible for switching the power to the ignition coil on and off, allowing the coil to store energy and release it as a high-voltage spark. This process is crucial for starting the engine and maintaining its smooth operation throughout different driving conditions. Without a properly functioning ignition control module, your vehicle may experience poor fuel efficiency, misfires, or even fail to start.
