Also just like I did with the 4V guys I'm welcoming everybody in this thread to come and understand ignition coils and systems to the fullest. In the next few weeks I plan on spending a lot of time educating everyone on ignition systems (specifically 2V COP) design, engineering of an ignition coil as well as answer any questions along the way over the next few weeks. Essentially imparting some of my Electrical Engineering knowledge to the 2V community.

I know there are many intelligent individuals in these forums but I am going to take this as slow as possible so please follow along with everybody else. I especially welcome those electrical savvy so that you can verify what I post isn't B.S. but sound electrical principals that work.

I'll start with this.... a very controversial subject but an interesting one. How would you feel knowing that the coils everybody is using isn't actually COIL ON PLUG but COIL NEAR PLUG?

Here is an excerpt from Wells who is a major ignition coil producer for many OEM's including GM.
WELLS Engine Management Systems: O.E. Quality & Coverage for the 21st Century

"Coil on Plug ignition is the latest development in precisely controlling spark intensity and timing for optimum power, fuel economy, and low emissions. Most 'coil on plug' (one coil for each spark plug) systems are actually 'coil near plug' because a short mechanical connector, or spark plug wire connects the coil to the plug. True coil on plug systems, with the coil mounted directly to the plug, are now being introduced on both domestic and foreign engines....

A strong spark requires high voltage.

CIRCUIT COMPRESSION
High-voltage circuits always risk degratation at any connection point between two parts. High voltage also will escape from its intended circuit whenever it finds an easier path to ground because of component failure or insulation breakdown. With coil on plug, there is no high-tension lead.... The system 'compresses' the secondary ignition to the minimum number of components and reduces the distance high-voltage circuit must travel."

Below is a picture of all ignition coil solutions with their respective rubber boots off. In reading this technical documentation from Wells. (a highly respected ignition coil manufacturer) you can clearly see the differences in design between the WeaponX ignition coil and others.



Here you can see the external interconnects. As Wells described the COIL ON PLUG that we all thing really is COIL ON PLUG is actually COIL NEAR PLUG due to the external interconnect that connects the ignition coil to the spark plug. WeaponX has designed our 2V ignition coils as the real deal (TRUE COIL ON PLUG TECHNOLOGY!)! Since there is no mechanical interconnect the XCOP is a true coil on plug system that requires no bolts to hold them in place and no external wires to connect to the ignition coil. The next picture shows the internal interconnects.



Ignition coils use something that is called a power inductor. A power inductor is essentially a coil of wire wrapped aroud a ferrit core. (hence the term coil) This wrapping of wire around a ferrite core creates a magnetic field once power is running through it which I will post about at a later time in this thread in order to explain better.

When energy passes through this and creates a magnetic field what happens is the coil now stores energy commonly referred to as Henries in Engineering.

hen?Àry (plural hen?Àries)

noun
Definition: unit of inductance: the SI unit of electrical inductance, equal to an electrical potential of one volt induced in a closed circuit by a current varying uniformly by one ampere per second.
Symbol H

henries definition - Dictionary - MSN Encarta

There are many types of power inductors such as torroidal, and axial.

You can clearly see where the wire is wrapped is where the energy is stored in the coil. WeaponX used an axial designed power inductor so that the end of the power inductor connects direct to the top of the spark plug. In these diagrams you can see where the power is stored in all units and how far it must travel to get to it's destination.

The basics is that the less the number of connections and the less wire the energy has to travel through the better the spark output potential.

If there are any questions I can field feel free to ask. This is where we will be answering them!

Very interesting I might have to keep up with that thread.
Hell the ease in changing the plugs alone might be worth the $4XX price.
