Natural
gas comprises mostly methane (CH). In addition to this, it generally contains
ethane, propane and butane, long-chain hydrocarbons, water, hydrogen sulfide
(HS) as well as motionless gases such as carbon dioxide (CO) and nitrogen (N).
The composition, though, depends on a huge amount on the deposit. Natural gas
is compressed to 00 bars and hold as CNG (Compressed Natural Gas) in a stress
container on the vehicle.

The
gas is generally depressurized to seven bars by a high-pressure regulator and
supplied to the engine stimulation system through a particular mixing device
and mechanism. In contrast with gasoline, natural gas has a critical volumetric
energy substance. For that reason, natural gas can only virtually and
practically be applied in convey after being processed to fuel with advanced
volumetric power substance.

Environmental
View

It
will take less time that the earth used to be liberated of toxic compounds in
the atmosphere, nothing like today when each person is contributing a huge
quantity of waste gasses in the air. These waste gasses exit through the
vehicle’s exhaust pipe and into the atmosphere, free, free to pollute the
world.

The
subject matter for discussion is that which fuel contributes more, CNG
Compressed Natural Gas OR Normal Pump Gasoline. In speculation, CNG is
theoretical to be a lesser amount of harmful for the environment. Carbon
monoxide and non-methane hydrocarbons are reduced by up to 90 % in contrast
with gasoline (on a car without a catalytic converter).

The
process catalytic converter planned for gasoline leftovers mostly useless for
the degradation of nitrogen oxides and methane in natural gas processes
primarily due to low carbon monoxide values. However, the superiority and
quality of CNG in our country has led many to consider that it is not the clean
fuel as it should be. Local CNG suppliers use low-quality mixtures, introduce
toxins into the gas stream to save up money, and raise capacity. Even after
looking at these features, CNG is method cleaner in an interior combustion
engine than Gasoline. It creates pollution and produces global warming.

Merits
of CNG over Gasoline:

20-
25 % less carbon dioxide release.

Up
to 90% less carbon monoxide emission.

75-90%
less non-methane hydrocarbons.

80%
less ozone worsening perspective.

No
Acid Smell from the exhaust gasses.

No
capacity losses through vaporization from the tank while refilling.

No
carcinogenic materials.

Less
costly than gasoline.

Demerits
of CNG over Gasoline:

Intense
methane gas emission.

50 –
100 % more nitrogen dioxide emissions.

20-
30% less power production with existing double fuel engines at optimized
conditions.

Additional
fuel station network essential rising Fire Risk.

Weight
and Space requirements for gas cylinders in a vehicle.

Frequent
Fill-ups.

Perilous
Fire risk in case of Accident.

Dangerous
outburst exposure in case of Accident.

Fire
Hazard in case of gas trickle &/or substandard cylinders.

Low
Reliability.
