Which component provides the electrical spark to ignite the air/fuel mixture?

The ignition system is responsible for creating the electrical spark necessary to ignite the air/fuel mixture in an engine. This system includes components such as the spark plugs, ignition coil, and ignition control module. When the ignition system is activated, it generates a high-voltage electrical charge that travels through the ignition coil to the spark plug. The spark plug then produces a spark at the right moment to ignite the compressed air/fuel mixture in the combustion chamber, enabling the engine to run smoothly.

In contrast, while the fuel injector plays a crucial role in delivering the appropriate amount of fuel into the engine, it does not generate the spark. The starter motor is primarily responsible for turning the engine over during the initial start-up but does not create ignition. The battery provides electrical power to all electric components, including the ignition system, but it does not directly create the spark itself. Thus, the ignition system is fundamentally essential for the ignition process in an internal combustion engine.
