1. Noun interpretation of an independent ignition system
independent ignition, English as Coil-On-Plug, abbreviated as COP. Coil-On-Plug Chinese literally translated as “coil to the spark plug” coil mounted directly on the spark plug, a cylinder i.e. a separate coil, commonly known as “independent ignition.”
independently of each cylinder firing is assigned an ignition coil, the ignition coil is mounted directly on top of the spark plug, so that a high voltage is also canceled. This ignition by camshaft sensor or by monitoring to achieve accurate cylinder compression ignition, it applies to any number of engine cylinders, especially for the use of four valves per engine cylinder. Since spark plug ignition coil assembly may be installed in the middle double overhead camshaft (DOHC), the full use of the interstitial spaces. By eliminating the distributor and power lines, energy conduction lossesMinimal leakage losses and loss, there is no mechanical wear, and the ignition coil and a spark plug of each cylinder are fitted together, the external metal wrapper, substantially reduced electromagnetic interference, can guarantee the normal operation of the engine electronic control system. Working Principle
2 independent ignition system
The working principle of an independent ignition system and other ignition system is substantially the same. Typically ignition coil which has two sets of coils, the primary and secondary coils. The reason why the car ignition coil capable of low voltage becomes a high voltage, the transformer is due to the same general form, the primary coil than the secondary coil turns ratio. When the primary power coil, with the growth of the current four weeks to produce a strong magnetic field, the magnetic field energy storage core; switching means when the primary coil circuit is disconnected, the rapid decay of the magnetic field of the primary coil, the secondary coil will It induces a high voltage. The primary coil magnetic field disappears faster, the higher the current instantaneous current interruption, the greater the ratio of turns of the two coils, the higher voltage induced in the secondary coil.
