[FWDLK] Bendix Electrojector

[Bob Oswald <punch@xxxxxxxxxxx>]

I guess there WAS an SAE paper published by Bendix Corporation on their
system, in 1957, but I don't know exactly when.  The Bendix system was
licensed to Bosch in Germany and used by VW Porsche as the purely
mechanical  K-Jetronic system starting with the VW 1600 in 1967 and then
was widely used including in the Porsches in later years (is it still
around?).  Apparently  the K-Jetronic delivery and metering system was
derived from their diesel injection pumping system, because Bosch
mistrusted solid-state control systems in the early years.
        The Bendix system was also licensed to AE-Brico and to Lucas Electric in
England and in modified form (developed by Bosch and Lucas together) used
on Jags (6 and 12 cylinder) and again may still be being used for all I
know (what's a new Mercedes or Audi got?).  Lucas developed an ECM system
to run the fuel injection plus other engine and transmission components,
which was apparently a very good system.  I wonder if it had any relation
to the ECM systems that the Big Three picked up in the 80's?
        The Lucas system depended on providing variable length pulses of fuel to
the cylinder banks (one half of the engine receiving its pulse at the same
instant, which apparently is still very efficient) in response to manifold
pressure.  The early K-Jetronic system had individual plungers delivering
fuel to specific cylinders in a timed fashion, but the later system as
found in the Porsche 917 delivered a continuous spray of fuel into the
inlet ports and varies the quantity of fuel in response to measured air
mass flow.
        So I guess all of these, and probably a lot more besides, came out of that
Bendix design from the fifties.  Pity Chrysler didn't persist with it a
little longer.  One interesting footnote is that electronic fuel injection
was purely a luxury car toy until California's strict new emissions
requirements made it advantageious for VW to think of using it in their
humdrum 1600.  And now how many new vehicles DON"T have fuel injection?
