Replacement spark plugs for AGM D8EA
The plug is connected to the high voltage generated by an ignition coil or magneto. As the electrons flow from the coil, a voltage difference
develops between the central electrode and side electrode. No
current can flow because the fuel and air in the gap is an
insulator, but as the voltage rises further, it begins to change
the structure of the gases between the electrodes. Once the voltage
exceeds the dielectric strength of the gases, the gases become ionized. The ionized gas becomes a conductor and allows electrons to flow
across the gap. Spark plugs usually require voltage of
12,000–25,000 volts or more to 'fire' properly, although it can go
up to 45,000 volts. They supply higher current during the discharge
process resulting in a hotter and longer-duration spark.
As the current of electrons surges across the gap, it raises the
temperature of the spark channel to 60,000 K. The intense heat in the spark channel causes the ionized gas to
expand very quickly, like a small explosion. This is the 'click'
heard when observing a spark, similar to lightning and thunder.
The heat and pressure force the gases to react with each other, and
at the end of the spark event there should be a small ball of fire
in the spark gap as the gases burn on their own. The size of this fireball or kernel
depends on the exact composition of the mixture between the
electrodes and the level of combustion chamber turbulence at the
time of the spark. A small kernel will make the engine run as
though the ignition timing was retarded, and a large one as though the timing was advanced.
