An automobile engine is equipped with several cylinders, and a spark plug is mounted on the cylinder liner of each cylinder. An automobile ignition system includes components such as a battery, ignition switching, ignition coil, distributor and spark plug. When ignition switching is turned on by the ignition system circuit, the current is routed through the primary coil of the ignition coil to excite electromagnetic induction by rapid opening and closing of the platinum contacts of the distributor, generating a high voltage current, and High voltage current is transmitted from the secondary coil to the distributor's high voltage input joint, high voltage current is sequentially transmitted from each distributor's high voltage input joint to each spark plug, and each spark plug splashes the spark in turn. The engine generates power to ignite the gas mixture placed in the cylinder.
