Thanks guys for finding the links to that car..
I'm only a curious observer, watching and trying to learn.
Let me share the beer talk me and my friends have about
it. I don't know if I'm correct. Just speculation.
Well first, its a vapour system. The coils heat the fuel
but only fuel vapours go into the engine.
The carburator, we think, was only used to get the engine
up to speed. Once up to speed, the vehicle would just run
on vapor to maintain speed.
Here's some interesting speculation. They put the
motor in an insulated box to stop heat from escaping.
The actual engine ran much cooler than what we
see in our day to day commuting machines. We
think the engineers knew that if you lose heat then
you lose efficiency.
That's why rather than shedding unwanted heat by disposal
of it in the heat wastebin (radiator) these engines had no
such wastebin. They instead tried to preserve every piece
of heat they had and not any escape.
Vapour technology is interesting. I can't claim to be an
expert in it.
Now, that motor had no twin cams and was OHV. No VVTI,
or any of the things the brochures say we need today.
Of course, in reality it may have been on 30hp or less.
But it raises some very interesting questions.
