1.9 Nozzles
A nozzle is mounted in each cylindre’s individual inlet channel of the inlet manifold and connected to the injectors
by means of a suitable tube.
Technical specifications:
Calibrated pass-through hole: Ø 4 mm
Connection to the fuel rail: outside Ø 6 mm
Manifold connection: M6 x 1 thread
1.9.1 Nozzle installation instructions:
The correct installation of the nozzles is crucial for the good operation of the engine. These must be installed
exclusively with the prior removal of the manifold.
-
Dismantle the suction manifold taking care not to damage the gasket. Carefully note the connections and
assembly of all the components installed on the manifold.
-
Following the instructions provided on the “vehicle cards,” make the holes for installing the nozzles on the
manifold.
-
In the event that no vehicle card is available to define the positions of the nozzles, place them as close as
possible to the petrol injector.
-
Mark the points to be drilled.
-
Before making the holes, punch the exact points where the holes will be made.
-
Apply grease to the point of the drill bit so as to avoid spreading swarf, then drill using a 5-mm bit if the
suction manifold is made of aluminum alloy. In the case that the inlet manifold is plastic, use a 4.8 mm bit.
During drilling, it is important to keep the drill in a perpendicular position with respect to the surface to be
drilled.
-
Tap a thread with a male M6x1.
-
Carefully clean the inlet manifold and remove all the drilling swarf.
-
Take care not to damage the threads in tightening the fittings.
-
Use a drop of brake thread sealant in the coupling to improve the grip.
-
Reassemble the inlet manifold and use new manifold gaskets, if necessary reassemble all the components
previously removed during the course of the dismantling operation.
1.10 Water temperature sensor
This sensor is used to measure the engine temperature. This signal is used by the ECU to determine when to
switch over to gas.
The electric signal is sent to the ECU as part of a string of information necessary for the engine running on gas.
Technical specifications:
Weight 71 g.
Tube connection 15 mm
Sensor type 4.7 ohm
Connector IP 54 type SICMA 2
Legend:
1. Water hose connections
2. NTC temperature sensor
3. Electrical connection
Installation intruction Temp. sensor:
The temperature sensor is fitted on the cooling
circuit just upstream of the pressure regulator.
