Special features
From
1977
models, the fast-idle electro-valve
(9)
is manufactured by
« PIERBURG
When
it is not
energized, the electro-valve
lets
low
pressure
through to.wards the curburettor
capsule (fast-
idle
),
contrary
to
the
«
WEBER
»
électro-valve
fitted previously.
Fitting
the
« PIERBURG »
electro-valve
necessitates
fitting
a relay (8)
which is
energized
wien
the
air-
conditioning
system
is operating.
This
relay
with its
«
open
»
contact cuts
off
supply
to e1ectro-valve
(9)
whih
therefore
produces fast-idle.
The
rest
of
the
operation is identical
to
the
preceding
diagram.
