Principle: 1, when the ignition switch to the starting position or back to the ignition position after starting, the ignition circuit working current mountain battery (), ignition switch contact 30 and the first way to provide power to the ignition controller, Hall pulse generator power supply;
2, the second way, the primary winding of the ignition coil, the ignition controller, and the electric storage he (1), so the iron core in the ignition coil generates a magnetic field under the action of the current. When the missing rotor of the distributor interacts with the Hall element, the operating current in the primary winding of the ignition coil is disconnected through the ignition controller. The magnetic field in the core of the ignition coil will quickly disappear;
3, so the secondary winding of the ignition coil will produce high pressure, the distribution rotor in the distributor will be distributed to the cylinder spark plug according to the working ignition order of the engine. The gap between the center electrode and the side electrode of the spark cold is broken down, resulting in a flameout spark to ignite the combustible mixture.
