4.3 Before starting the conversion
Before proceeding with the conversion it is necessary to
retrieve the file pertinent to the vehicle to be converted.
This file is available in the LIS software archive and/or
on paper.
Check the vehicle for the following:
- Air filter
- By using the oscilloscope check that high voltage
wires, spark plugs, and coil(s) are within OEM
specifications.
- Intake and exhaust valves, when mechanical, must
have the clearance specified by the OEM.
- The Lambda sensor must be in good operating
condition and have the appropriate voltage span.
- The catalytic converter must be in good operating
condition.
Perform the adjustments and/or modifications that are
required by the above-mentioned diagnostic procedure,
and when necessary replace deficient components, with
particular emphasis on the Lambda sensor.
4.4 LIS components installation
4.4.1
Regulator-vaporizer
The regulator can be installed by observing the following
procedure :
- Install the regulator in the engine compartment in the
position indicated in the relevant “vehicle file.” Mount
the unit directly or indirectly onto the vehicle’s body
or on the frame by means of the provided fixing set
- Do not mount the regulator on the engine or other
components that are in turn mounted on the engine.
- Do not install the regulator in the area of the passenger
compartment ventilation system; also ensure that the
regulator is not installed close to the air intake for the
passenger compartment ventilation system.
- Install the regulator not closer than 150 mm from the
exhaust system, or mufflers. If this is not possible, a
heat shield in metal or equivalent with a minimum
thickness of 1 mm must be installed. In any case, do
not install the regulator closer than 75 mm away from
the exhaust system.
- Mount the regulator in such a way to allow easy access
for adjustment and maintenance.
- Mount the regulator below the engine’s water table
in order to avoid airlocks in the cooling system.
- Make sure that the regulator’s drain plug is not
positioned on top of the ignition distributor, or ignition
coil(s).
- Thoroughly clean the LPG tank and tubing before
installation in order to prevent dirt from accumulating
inside the regulator.
- When the installation is complete, start the engine and
allow it to reach normal operating temperature, then
make sure that there are no water leaks and that the
regulator warms up quickly.
- Each time the cooling system is drained, it is necessary
to restore the coolant level to the recommended OEM
specifications, taking care to eliminate possible
airlocks that could prevent heating of the pressure
regulator.
When connecting the regulator’s fuel outlet to the
proportioner, take care not to create sharp bends or tight
curves in the connecting hose.
