On what do you base that contention? I have to

That's not what these plugs claim to do. That's what
a simple stratified charge engine does, though.

What on earth are you talking about? Certainly not
these spark plugs...

You're saying that they take otherwise normal SI
gasoline engines and remove the ignition system, and
instead insert glow plugs that run the engine until
warm, at which time the engine runs as a diesel using
pump gasoline? There's got to be a major piece
missing in that puzzle, because that's physically
impossible (continual compression ignition or hot-spot
"dieseling" of a regular SI engine will destroy it in
fairly short order).

Unless they are demanding exclusive rights to market
the plugs as part of the agreements, he can sell them
however he wants, whether they use them or not.

Not cerificated aircraft, as that would be a violation
of FAA regulations. These must be experimental
aircraft, and those generally run auto or motorcycle
I'm still missing something in the puzzle of how these
things supposedly operate, though.

That's truly astonishing. Perhaps you can arrange a
demonstration for me? I'd love to write an article

Wait... They developed a device that is for SI
engines, but they specifically did NOT include SI
engines in the patent?

So the timing is "static", with the only variables
being the burn rate of the mixture and its
compression/dilution? Since timing is required to
advance with engine speed in SI engines, you're saying
they mechanically change the shape and size of their
plugs while inside the engine, somehow connecting this
to engine speed?
> Proven beyond a doubt
Since you seem to be indicating that they violate a
number of the laws of physics, I have to question how
they could be "proven beyond a doubt". Either there
is some major part of the puzzle not being spoken of,
or the claims are false.
