This in turn leaves less energy over to continue the arc that would normally run for a few milliseconds. The plug does nothing a standard plug does not do, EXCEPT wears slower as there are more electrodes to wear out, so the spark stays strong longer.Īs a plug wears the voltage required to simply get the spark started is higher, so more of the available ignition energy is used simply to get the spark started. Plug temperature selection is a different thing all together.ģ.the benefit of the plug is really when you're pulling the throttle at a consistent situation like cruising therefore it's also beneficial in high speed riding? Plug temperature is a function of plug design, mostly lenght of center eletrode, nothing to do with number of electrodes. Where did I say that? it is the same spark, but the plug in effect wears slower so the spark remains strong for longer.Ģ.this multi spark plug design is better for the plug's life itself bec it doesn't burn too hot. The design advantage of the multiple electrode plug in itself is the wear is slower over the service period.the rest is marketing.ġ.the brisk plug fires a weaker spark but is more efficient. So more or longer sparks can give better economy in leaner conditions such as cruise. Both burn well once started, but the smallest of flames gets the well covered field ablaze easily. Imagine trying to start a sparsely covered straw field to burn as apposed to a well covered field.

The three electrodes also tend to spark from different thirds of the center electrode outer diamater, giving better wear there too.īut there is the thing, you get ONLY ONE SPARK! The spark does not split up and go there ways, it simply takes the path of least resistance, usually the smallest or wettest (with fuel vapor) gap.īut multiple sparks, or as today's higher voltage ignitions provide, longer sparks, do help fire a lean combustion mixture as the leaner you go the more spaced the fuel molecules and the harder to get a full flame front happening.
By using three electrodes you sppread this spark erosion over multiple electrodes to spread and lessen the wear. Much of the wear is on the earth electrodes and is mostly spark erosion. The three electrodes give better wear without the use of expensive exotic metals.
