The electronic ignition distributor plays the key role when a multi-cylinder engine ignition system with one ignition coil only. Ignition distributor is a part of gasoline engine that regularly distributes high-voltage electricity to the spark plugs of each cylinder according to the ignition sequence of the cylinder. When the rotor is rotating, the metal blades contact three terminal posts at a time. Thus, when the high voltage pulse of the ignition coil ‘s secondary resistance passes through the ignition wire, the pulse contacts a terminal through the metal blade of the rotor, then every component is timed. This terminal is connected by the ignition wire to the cylinder spark plug that happens to fire. As the engine runs, the ignition system continues to generate high pressure pulses, and at the same time, the spark plugs are allocated just in time to fire.
