INTRODUCTION TO CNG :
CNG (COMPRESSED NATURAL GAS) is obtained by
compressing purified natural gas to less than 1% of its
volume at standard atmospheric pressure. CNG is a
colorless, odorless, non-toxic but inflammable and lighter
than air.
BENEFITS OF CNG :
•
CNG is principally comprised of methane. Due to low
density it is compressed at a pressure of around 200
bars to improve the vehicle on board capacity.
•
Lower maintenance costs when vehicles run on CNG.
•
With rising petrol costs, CNG has seen the competitive
edge with its lower price and high availability.
•
Vehicle life-span can be prolonged since there is no
carbon generated during combustion and hence,
engine and the oil in the engine are much cleaner.
•
Due to its low hydro-carbon emissions, CNG is widely
considered to be an environmentally viable alternative
to petrol.
INTRODUCTION & SAFETY PRECAUTIONS
2. SAFETY PRECAUTIONS
To get the best out of CNG fuel, the engine must be tuned
and regularly serviced (both as regards to the mechanical
and the electrical parts) in addition to routine maintenance
required by the vehicle.
DO’S:
•
Never carry out any repair work on your own or from any
other personnel. Always get the car repaired / serviced
at
TATA authorized service centre only.
•
Ensure that the Battery Ground terminal is disconnected
before start of any repairs. Re-connect it once the repair
activity is completed.
•
Check CNG system components periodically for
leakage.
•
If you smell other than natural gas when refueling or if
you hear a hissing sound, follow these directions:
a. Do not panic. Park your vehicle in a well ventilated
area and apply the parking brake. Roll down all the
windows and keep the doors fully open for ventilation.
b. Turn the ignition switch to ’LOCK’ position.
c. Switch off ignition switch and manual shut off knob
located on cylinder valve before servicing / repairing
of any parts in the CNG circuit.
