DIS Explainations

[Bruce Plecan]

On these waste spark ignitions I've heard all kinds of explainations
for how they work, and the best logical one I've heard is that the
one cylinder at overlap doesn't fire because it's still surrounded
by exhaust gases.  But, as you retard the timing you get to the
stage that there is enought intake valve opening that it can light, that
cylinders mixture.  Soo given enough cam timing, or boost then you
can have a problem.  Or run a 0 overlap cam if running a turbo/
supercharger, to avoid this.
  For there to be a spark there first has to be a path of ionized gas
right???..  Or can you have a spark in  an environment of inert gas?? Bruce
Slippery slopes, are those the sides of a Cone Shaped Hat?
