Introduction:
independent ignition, English as Coil-On-Plug, referred to as the COP. Coil-On-Plug Chinese literally ldquo; rdquo coil to the spark plug ;, coils mounted directly on the spark plug, a cylinder i.e. a separate coil, commonly known as ldquo; independent ignition rdquo ;.
Principle: The working principle of COP and other ignition system is substantially the same as . Each coil has a low impedance, allowing the primary voltage becomes 40,000 volt spark plug to generate a spark. Of COP differs from the real ignition system and the other is: COP each coil mounted directly on the spark plug, the spark plug electrode voltage direct access, without going through the high voltage ignition wire or the distributor. This connection allows the spark as strong as possible, and to improve the reliability of the ignition system.
independent coils each spark plug using the coil means between the ignition time is longer. Increase ldquo; through the coil magnetic rdquo; time (setup time of the coil voltage of the coil magnetic field) may increase the voltage output of a high speed (RPM) of the coil; misfire most likely to occur at high speed.
