What is the difference between high voltage pack and ignition coil

1, structural differences: the high voltage package consists of a primary coil and secondary coil, in which the primary coil is connected to the power supply, the secondary coil is connected to the spark plug. Through the principle of step-up transformer will be converted from low voltage electricity to high voltage. While the ignition coil includes a primary coil and a secondary coil, the interaction of the magnetic field will be converted from low voltage to high voltage.

2, functional differences: the main function of the high-voltage package is to produce anode high voltage, provide focusing, accelerating, gate and other various voltages to ignite the combustible gases in the cylinder. Responsible for providing the high voltage required by the entire ignition system. And the function of the ignition coil is to convert the low voltage electricity into high voltage, and transfer that high voltage to the spark plug to ignite the gas mixture in the cylinder.

3, application differences: high-voltage packages are used in distributed ignition systems, where each cylinder has a high-voltage package responsible for ignition. Applicable to multi-cylinder engines, such as V-type engines or in-line engines. The ignition coil is used in the traditional point-split ignition system, in which a set of ignition coils are connected to the spark plug of each cylinder. It is suitable for older engine designs, such as decentralized ignition systems.
