SPECIAL FEATURES
From 1977 models the fast-idle electro-valve ( 9) is manufactured by 1, PIERBURG 1).
When it is not enerqized the electro-valve lets low pressure through towards the carburettor capsule (fast
idle ) contrary to the (1 WEBER )) electromvalve fitted previously.
Fitting the N PIERBURG )) electro-valve necessitates fitting a relay (8) which is enerqized when the air-
conditioning system is operating This relay, with its c( o/)t/i 1) contact cuts off supply to electro-valve (9)
which therefore produces fast idle. DESCRIPTION OF COMPONENTS :

7.; 1976 - Special features :
From 1977 models, the fast-idle electro-valve ( 9) is manufactured by (( PIERBLJRG )).
When it is not energized. the electro-valve lets low pressure through to.wards the carburettor capsule (fast-
idle ) I contrary to the (( WEBER )) electro-valve fitted previously.
Fitting the (( PIERBURG )) electro-valve necessitates fitting a relay (8) which is energized when the air-
conditioning system is operating. This relay with its N open )) contact cuts off supply to electro-valve ( 9)
which therefore produces fast-idle.
The rest of the operation is identical to the preceding diagram. DESCRIPTION OF COMPONENTS :
