Ignition Coil: Introduction to the Core Components of the Car Ignition System

Different Types of Car Ignition Systems

Market mainly consists of three types of car ignition systems, which can be broadly classified into traditional circuit breaker ignition, electronic ignition, and distributorless ignition.

In response to the increasing demands for automotive performance, especially the quest for higher mileage, reduced emissions, and enhanced reliability, electronic ignition systems have gained popularity.

Electronic ignition systems come equipped with a distributor. The traditional points of the circuit breaker have been replaced with pickup coils, and an electronic ignition control module has been integrated.

Upon turning on the ignition switch, primary current flows from the battery, through the ignition switch, to the coil's primary winding. The primary current is intermittently switched on and off by the armature's action, as it rotates past the pickup coil or sensor. The approach of the armature's teeth to the pickup coil generates a voltage that prompts the electronics module to cut the primary current to the coil. The magnetic field of the coil vanishes, and a timing circuit within the module reactivates the current. Nonetheless, when the current is interrupted, the magnetic field within the coil collapses swiftly, producing an extremely high voltage in the secondary winding of the coil. This high voltage then propels through the secondary ignition circuit, similarly to a conventional ignition system.

The Basic Principle of Ignition Coils

Car ignition systems encompass various components, each playing a pivotal role. Among these, ignition coils are fundamental. The basic principle that allows an ignition coil to generate the required high voltage is the interplay between electricity and magnetism. When an electric current travels through an electrical conductor, such as a coil, it induces a magnetic field around it. This magnetic field, or magnetic flux, represents a form of energy storage that can be converted back into electrical energy. Upon activating the current, it swiftly escalates to its peak value, while the magnetic field or flux slowly intensifies to its maximum level, stabilizing as the current stabilizes. Conversely, when the current is disrupted, the magnetic field abruptly collapses towards the coil.
