direct-ignition system
Quick Summary
A direct-ignition system, also known as a distributor-less ignition system, is a component of a gasoline engine that produces an electric spark to ignite the fuel-air mixture. This ignition process generates the motive force for the engine.1
In these systems, high-voltage pulses are directly applied to coils that are situated on top of the spark plugs. The primary components include a coil pack, an ignition module, a crankshaft reluctor ring, a magnetic sensor, and an electronic control module. The ignition module manages the primary circuit to the coils, controlling their on and off states. The reluctor ring, mounted on the crankshaft, triggers the magnetic sensor as it rotates. This sensor then sends position information to the electronic control module, which is responsible for managing the ignition timing. This setup offers greater reliability and improved engine control compared to older systems.1
