Surface discharge plugs: they guarantee a safe cold start
It has a minimum of two ground electrodes, placed laterally and with the tapered tip. If the insulator is clean, spark jumps out of the tip of the Center electrode to the upper end pointed one of the electrodes of mass.
When the insulator is sooty, this type of spark plugs guarantee cold safe boot, as well as the cleaning of the insulator even below the self-cleaning temperature.
In addition, when this circumstance occurs, spark slides the tip of the insulator and jumps to the lower end of the ground electrode. To do this you must overcome a smaller resistance than to slip to the insulator.
In this process not only burns the air / fuel mixture, but that with each spark also cleaned the charcoal from the tip of the insulator. Once completed, returns to normal sparks jump from the Center electrode.
