What are the manufacturers of automobile ignition coils?

Automobile ignition coil manufacturers are Delphi, UMC and Denso.

Ignition coil:

(1) With the development of automobile gasoline engine in the direction of high speed, high compression ratio, high power, low fuel consumption and low emission, the traditional ignition device can no longer meet the use requirements.

(2) The core components of the ignition device are the ignition coil and the switch device. Increasing the energy of the ignition coil can generate enough energy sparks, which is the basic condition for the ignition device to adapt to the operation of modern engines.

(3) There are two groups of coils in the ignition coil, primary coil and secondary coil. Thick enameled wire is used for primary coil, generally with 0.5- 1 mm enameled wire for about 200-500 turns; Fine enamelled wire for secondary coil is generally 0. 1mm, about 15000-25000 turns. One end of the primary coil is connected to the low-voltage power supply (+) on the vehicle, and the other end is connected to the switching device (circuit breaker). One end of the secondary coil is connected with the primary coil, and the other end is connected with the output end of the high-voltage line to output high-voltage electricity.
