CNG Full Form | What is the Full Form of CNG

Compressed Natural Gas

CNG stands for Compressed Natural Gas.
It mainly comprises methane gas which can produce engine power after it's mixed with air and fed into an engine's combustion chamber. So, it is used as a substitute for Diesel, Petrol and Propane/LPG.
It's effective to control air pollution because it produces fewer undesirable gases in comparison to Diesel, Petrol and LPG. So it's more environment-friendly than other fuel products.
It's safer than its other substitutes within the case of the spill because it's lighter than air and disperses quickly when released.

Brief History of CNG

The use of natural gas as a fuel for vehicles was introduced within the late-1800s.
The first natural gas Vehicle was patented within the USA and soon after the Second war, Italy and various other European countries adopted CNG as a primary fuel.
CNG is found over oil deposits. It can also be collected from landfills and wastewater treatment plants.
It's made by compressing gas to but one percent of its standard atmospheric pressures.
It's stored and distributed in very hard spherical or cylindrical containers at the pressure of 20-25 mpa.

CNG is used in combustion engines which are modified or manufactured for CNG use. It's generally used in Buses altogether over the world.
In India, it's used in Buses also as in three-wheeler Autos.
Its use as a vehicle fuel was introduced late in the eighteenth century and the first gas Vehicle (NGV) was patented within the U.S.
After war II, it had been accepted as a main source of fuel by Italy and some other European countries.

It is cheaper than its other substitutes e.g. Petrol and Diesel which are used to run buses, cars and other automobiles.
The maintenance cost for the vehicles that run on CNG is low as compared to the vehicles run on Petrol and Diesel.
It is more environment-friendly because it emits less undesirable and harmful gases than other substitutes i.e. Diesel and Petrol.
It enhances the lifetime of lubricant oils because it doesn't contaminate and dilute the crankcase oil.
It provides a high auto-ignition temperature of 540 degree Celsius or more.

The cost of CNG is very high and about 30 to 35 thousand spent to put CNG in your car.
Driving on CNG heats the engine of the vehicle,
Applying CNG requires a lot of care for oil and air filters.
If you drive a vehicle on CNG, it’s recommended that you change your oil from time to time and also check the air cleaner.
Installing CNG in a new car expires its warranty period.
