DAILY CNG AND CNG WITH "RECOVERY MODE"
Note For anything which is not specified in this attachment, please refer to the indications provided in the previous Sections.
B.1 GENERAL INFORMATION
Natural gas is a mixture consisting mainly of methane (main component), ethane, propane, carbon dioxide and nitrogen.
In order to make it more noticeable, an odorant is added (THT) providing the characteristic smell of sulphur.
The composition of natural gas can vary considerably, therefore also its chemical - physical characteristics can be significantly differ-
ent.
Natural gas is compressed in cylinders for transport and for use on the vehicle. this is where its name CNG, Compressed Natural
Gas comes from.
Within the range of DAILY vehicles, the CNG and CNG with ”Recovery Mode” versions represent IVECO's contribution to
providing a transport system which respects the environment as much as possible.
These versions differ from the others for the specific solutions applied to some engine components, particularly for the electronic
management, the presence of the gas cylinder frame and the relative pipes.
On versions with "Recovery Mode" there is also a small petrol tank which is activated automatically and for short trips if the gas has
been depleted.
The increased technical complexity must therefore be taken into account by the Body builder both with regards the study of the
conversion and especially during its implementation.
▶
The characteristics of highly flammable compressed gas do not permit the outfitting or conver-
sion of vehicles for fire fighting applications or for use in potentially critical environments (eg:
airports, refineries, etc.).
Note IVECO designs, approves and constructs CNG vehicles which comply fully with the Regulation ECE 110 currently in force.
Interventions on the engine power supply system which:
a) use components other than those approved by IVECO (even if approved as Standard rate Technical Unit)
b) modify the original architecture (for example: moving or adding a cylinder, cylinder retainer method)
require the reapproval of the vehicle.
To this end, the designated Authority may require the complete documentation (calculations, diagrams, test reports) certifying
compliance with the requirements of Regulation ECE 110 for all the modifications made to the original system.
The financial cost involved in reapproving a vehicle are borne by the Body builder.
B.2 SAFETY REGULATIONS
During refuelling operations
●
When refuelling, the gas is usually compressed to 200 bar. Small amounts of natural gas can be released during refuelling. Fol-
lowing a rapid decompression a cooling may occur, leading to potential ice burns on the skin. Wear protective gloves when
refuelling.
●
Do not smoke or handle naked flames or flammable sources of light.
●
Before filling the gas pressure system, check it shows no visible defects.
●
The vehicles to be refuelled must be locked so as to prevent any movement; The engine must be switched off and the ignition
key must be removed from the ignition.
●
Keep adequate extinguishers (A, B or C class) and other fire fighting devices close at hand. Fire class C is particularly suited for
CNG.
●
Do not release the content of pressurised gas pipes or cylinders into the atmosphere.
