▶
The breather valves are essential for the safe operation of the system and therefore must always
be accessible. Please read the Use and Maintenance Manual carefully for all indications in this
regard.
d) ATS system (After Treatment System)
The insulators and the heat shields must remain in their original position. Any modification must receive prior authorisation from
IVECO.
e) Gas pipes
Any modification of the pipes must be compliant with Standard ECE R110 and all the components must be type-approved accord-
ing to ECE R110.
Lengthening the pipes may have a negative impact on performance due to reduced injection pressure (especially for the LNG ver-
sion).
Do not reposition components of the gas system such as the regulator, sensor or filter without having received explicit authorisa-
tion and approval from IVECO.
▶
It is strictly prohibited to modify the diameter of the gas pipes.
A.5 EMPTYING THE CNG SYSTEM
Note Contact the IVECO Service Network before carrying out any intervention.
▶
Before any welding operations on the vehicle or maintenance operations on the engine, the fuel
system must be fully "ventilated", i.e., it must be emptied of gas.
It is usually sufficient to partially empty the circuit, namely, empty only the pipes; however, to operate in conditions of greater safety,
it is recommended that the entire system is emptied, including the cylinders.
▶
The emptying operations must be carried out while the engine is OFF and in an environment
with suitable air exchange (a forced air exchange is preferable).
▶
To limit the release of uncombusted gas as much as possible, keep the engine running until the
pressure of the gas drops to the minimum value of 20 bar.
Note Consumption of the gas at a residual pressure of 20 bar is a procedure which is less harmful to the environment than releasing the
gas directly into the atmosphere.
