According to 'Bosch Fuel Injection & engine Management", by Charles
   Probst:

   The first continuous injection system (CIS) (1977) was K-Jetronic.
   Air flow
   is measured by a circular plate in the air-flow sensor, which is
   mechanically linked to the fuel distributor.  Until 1980, fuel
   delivery is
   strictly under mechanical control in direct relation to air flow;
   there are
   no electronics.  VW, Audi, and Mercedes call it CIS.

   K-Jetronic with Lambda Control is an adaptation of K-Jetronic mechanical
   control.  The mixture is modulated with a limited electronic control
   in a
   feedback system to maintain a precise air-fuel ratio.

   KE-Jetronic combines K-Jetronic mechanical control with total
   electronic
   modulation of the mixture.  It uses many of the same sensors used in
   L-Jetronic (a pulsed fuel injection system).  It's capable of full
   mechanical fail-safe if the electronics fail.  VW, Audi, and
   Mercedes call
   is CIS-E.

   Paul,

      First - I'm sorry for the typos, and 'editing' compliments of MS word
   'autocorrect'.  It didn't like 'Jetronic' apparently.  The systems
   described
   above are all 'Jetronic', not 'electronic(s)'.

      Second - the author of the 'Bosch..." book said his production year
   references (like the 'first seen in 1977' comment above were for the US
   market only.

      The chart lists injection in VWs from the Type 3s...

      On the history front - also from the Bosch book:

     "Bosch passenger-car fuel injection first appeared in 1927 as a diesel
   design using engine-driven pumps developing high pressure to deliver
   diesel
   fuel into the cylinders - direct injection.  In 1937, these pumps were
   adapted to aircraft engines, with both diesel and gasoline fuel
   applications.  In 19565, similar engine-driven gasoline injection
   pumps were
   developed for the Mercedes-Benz race cars and the 300SL production car,
   again injecting fuel at high pressure directly into the cylinders.

     "The fuel-injection systems described in this book first appeared
   about
   1967.  They are completely different from engine-driven systems,
   delivering
   fuel at much lower pressures at the intake ports, and are generally
   electronically controlled.  The early Bosch literature describes these
   systems as "non-driven".  Bosch coined the term "Jetronic" to
   establish a
   common identity for their new designs in most of the 135 countries
   in which
   they operate.

More "me too"..  My '74 Volvo (wagon) had K-Jetronic.  '71's had dual SU
side drafts (our first Volvo) - lame.  '72's had electronic FI (I think
one year only - maybe the P1800's had more years).  And I think '73
through about '78 had K-Jetronic.  By '82 (our newest Volvo) they had
Lambda (O2 sensor).

The K-Jetronic ran fine, but had kind of weak throttle response.  As far
as throttle response, the sportiest Volvo I've driven is our '67 122S
with dual SU HS6's.  Kind of surprising since they don't have an
accelerator pump..
