Injectors
The solenoid valve controls the lift of the atomiser needle.
On the fuel inlet union a filter protects the injector for
impurities. The injector is constructively the same as
conventional ones, except that there is no needle return
spring.
Access to the injectors is gained by releasing the side
soundproof cover from the cylinder head. The fuel recovery
pipe has a quick coupling.
The injector comprises two parts:
-
actuator - atomiser composed of pressure rod (1), pin (2)
and nozzle (3)
-
control solenoid valve comprising a coil (4) and drive
valve (5).
1
st
phase: rest position
The coil (4) is not activated and the shutter (6) is in the closed
position.
The same fuel pressure acts in both the control area (7) and
in the pressure chamber (8), but as the shutter (6) is closed,
the needle (2) cannot be raised.
2
nd
phase: start of injection
The coil (4) is energised and causes the shutter (6) to move
upwards.
The fuel of the control volume (9) flows towards the backflow
duct (10) causing a drop in the pressure in the control area
(7).
At the same time, the pressure of the fuel in the pressure
chamber (8) causes the needle (2) to rise, resulting in fuel
injection to the cylinder.
3
rd
phase: end of injection
The coil (4) is not activated and makes the shutter (6) return
to the closed position, which re-creates a balance of forces
that makes the needle (2) return to the closed position and
consequently end injection.
Injectors (78247)
The solenoid valve is of the N.C. type.
The injectors are connected individually to the control unit at
the following pins:
-
A16 / A47 cylinder 1 injector
-
A2 / A31 cylinder 2 injector
-
A1 / A46 cylinder 3 injector
-
A17 / A33 cylinder 4 injector
