What Is The Secondary Ignition Circuit

Have you ever wondered what lies beneath the surface of your car’s engine? The secondary ignition circuit is one of the secrets that powers the modern automobile. Though it may sound complicated, this essential component of the vehicle is relatively simple to understand.

The secondary ignition circuit is a critical part of the electrical system in a car. It is responsible for delivering a high voltage spark to the spark plugs, thus igniting the air/fuel mixture inside the engine's cylinders. Without this spark, the car would not be able to start or run correctly.

To understand the secondary ignition circuit, it's important to first understand how it works and its components. The primary component of the circuit is the ignition coil, which harnesses the 12 volt current from the car battery and transforms it into a much higher voltage current. This current is then sent to the spark plug, which ignites the air/fuel mixture in the engine cylinder.

Another important component of the secondary ignition circuit is the spark plug wires. These are the insulated wires that connect the spark plug to the coil, carrying the high voltage spark to the plug. Spark plug wires are usually made of silicone-based rubber, and they must be replaced regularly to ensure proper performance.

Finally, the ignition control module is an important part of the secondary ignition circuit. This module monitors the engine's timing and temperature, and sends signals to the ignition coils to fire the spark plugs. Without the ignition control module, the car would not be able to start or run correctly.

Overall, the secondary ignition circuit is an essential part of the car's electrical system and should be taken care of properly. By understanding how it works and its components, you can ensure that your car runs at its peak performance. With regular maintenance and replacement of parts, you can keep your car running strong for many years.
