CNG is a compressed form of natural gas that can be used as an alternative fuel to diesel, petrol and propane. It has several advantages over other fuels such as being cheaper, causing less pollution and requiring lower maintenance costs. However, CNG vehicles require more space due to the onboard fuel storage tanks, which decreases available interior space. Overall, the document concludes that CNG is a useful fuel for vehicles to reduce pollution and costs compared to other fuels like petrol and diesel.

4.  PREPARATION
it is made by compressing of natural gas
(composed of methane) to less than 1% of
the volume at standard atmospheric
pressure.It is stored in hard cylindrical
containers at a pressure of 200-280 bars.
CONSTITUENTS PERCENTAGE(%)
METHANE 88.5
ETHANE 5.5
PROPANE 3.7
BUTANE 1.8
PENTANE 0.5

5.  IMPORTANCE
 it is lighter than air
 it is dispersed quickly when it released
 it releases less carbon into atmosphere
 it is cheaper than any other fuels

6.  comparision of prices
type of fuel price in RS.
petrol 87.84
diesel 79.13
cng 48.00

7.  ADVANTAGES
 less pollution and more efficiency
 it increases life of lubricating oils
 low maintenance cost than other vehicles
 "the napa valley wine train" successfully retrofit a diesel
locomotive to run on compressed natural gas before 2002 .
it's the first locomotive

8.  FIRST CNG BIKE
 This was the first
cng bike . It was
from argentina
company
"ZANELLA"

10. CNG IN INDIA
Govt. of India is taking number of policy measures to increase the use of natural gas
in CGD sector, some of which are as follows:
 Replacing costly and polluting fuels with Natural Gas
 Mandating CNG in various cities (e.g. Delhi and Mumbai).
 Creating of CGD infrastructure in smart cities..
 Inclusion of more number of cities by Petroleum and Natural Gas Regulatory
Board (PNGRB) for development of City Gas Distribution (CGD) network..
 100% allocation of domestic gas for domestic PNG and CNG segments for faster
roll out of PNG connections and CNG stations in given City/Geographical Areas..
 Development of Gas Infrastructure in Eastern part of the country. .

11.  DISADVANTAGES
 CNG contained cars
requires more space than
other vehicles
 Due to this the space in the
car decreases with the
presence of fuel tank

12.  CONCLUSIONS
 Due to this above reasons CNG most useful for
vehicles for vehicles as a fuel to reduce the pollution
and it is cheap than other fuels like petrol and diesel
