Dark Side Update

[Robert Harris]

Reviewing some mandatory reading of Dogma provided by the Supreme Grand High
Instigator in Arkansaw reveals some interesting insight.   The first practical
GASOLINE fuel injection was by Mercedes for aircraft engines using direct
cylinder injection.   Operational in 1939ish.   The whoosy port injection
system was invented to retain some of the benefits without the expense, and
even later yet, Continuous flow systems such as the Hilborn and Bosch CIS were
invented to reduce the costs of the then ridiculously overpriced port
injection systems.   Not quite what the dweebshite pronounce daily in their
infinite arrogance.  Was it Einstein? "The difference between genius and
stupidity is that genius has bounds" 

What is interesting to note is that all the early direct injection system
injected the fuel thru the side of the BLOCK and directly on to the exhaust
valve.  Both OHV and OHC - mainly Mercedes.  Timing was critical to the extent
that all the fuel had to get into the cylinder prior to the injector being
blocked by the uprising piston.  Now this is going to entail two holes in the
block per cylinder for the Dark Side demonic 8 - one for direct injection and
one for something else.  Better than a hole in the head - saylor?

Not having the benefit of having ME-101 Orthodoxy rammed home aurally by some
enlightened grad student who has never ran an engine on a dyno, silly me
actually believes what the squarehead engineers discovered - that over
hundreds of thousands of hours of testing on engines that their comrades lives
depended on, optimum power and economy ( both required for a fighter in
defense of the homeland ) was developed by using the hot exhaust valve to
vaporize the fuel.  The same baseline knowledge that went into the much later
port injection derivatives - aim the fuel at the back side of the intake valve
to keep as much fuel off the port floor as possible.  But - hey what did they
know - they only invented and perfected fuel injection before most of our
daddies were born.

So we haff discovered a cheap 8 cylinder desiel injection system and are now
proceeding on adapting it to at least one test engine.  Will blend some
synthetic 2 cycle oil initially to keep pump alive.  You haff no ideer of da
Konkoctions being considered for the fuel.  The initial target engine is a
flathead Ford V-8 - a far more recent "modern" design than those antique silly
overhead cammers, using the oldest fuel injection method - direct injection

And since I despise Gunnerman and actually understand Glassman and Ricardo,
there will be a blending chamber ahead of the inlet to the pump and a variable
blend of water, fuel and whatnot will get sucked into the pump and squirted
into the cylinder at 1500 to 2500 psi.  Homogenize that -  A-21 bright yellow
Pogue Carb Hype Shyte.  You might want to read Irwin Glassman's Combustion -
third edition to find out what really happens when a homogenized blend of fuel
and water is burned.   But don't let facts interfere with fantasy.

Control of the system will be easy. Drivers foot controls fuel, computer
catches up and controls air only.   We darksiders know that only two mixture
ratio's are "optimum" - pig rich - about .8 lambda and lean misfire - so we
don't even care about the air as long as its in between.  Another long story.
Think stepper motor to move the main air plates about, Ford IAC to feedback
and compensate for EGO.  More will be revealed.  Yes virginia, the dark side
is rapidly converging to a working EFI - without dweebish input or consent.

And if you are not prejudiced against knowledge, you might want to think about
the fact that a carb venturi generates a usable flow signal over about a 900
to 1 range vs most modern EFI ranges of 30 to 1 or so, and that Ford on some
of its Indy racer motors used a pressure sensor to measure the pressure drop
generated in a venturi to meter the fuel.  Reference a ridiculously sensitive
Ford one bar Map sensor to air above venturi, other side to vacuum, pressure
change corresponds to air flow - blow thru suck thru boost no boost makes nada
difference.  Light filter on output and would be totally insensitive to any
boost,  cam, intake air reversion or what ever without even burning up
computation or changing sensor.  Interested - ask me how someday when I don't
feel like all humanity sucks and reeks - probably before I go to work and face
the great unwashed retail public.
