Question

What does CNG stand for?

Answer 1

CNG is one of the fuel gases which is used as a fuel. It stands for compressed natural gas, and its component mainly comprises methane, and this methane gas is present at a very high pressure and stored in hard cylindrical containers. This name is common when speaking about automobile fuels and cleaner fuel.

Complete answer: CNG is the acronym for compressed natural gas. It is largely methane gas. It is termed as “compressed” since the methane gas is compressed to less than $1\%$ of its volume that it would occupy generally at normal atmospheric conditions. The pressure in which it is stored is roughly around $20 - 25MPa$ .
Speaking of its advantages, the two main advantages that this fuel has is:
1. Cheaper cost
2. Environmentally friendly.
However, even after being such a good source as a fuel, this CNG isn’t used as much as it should have been since the installation amount the vehicle’s owner has to bear far outweighs the cost-effectiveness of this fuel to a private vehicle user. However, for a commercial vehicle, which earns and runs on a daily basis, such as auto-rickshaw, taxi, buses, etc, the installation of this fuel gas storage is viable and thus is used by commercial vehicles mostly.

Note:
With the growing technology and advancement and development in the field of fuel chemistry, the advantages of CNG gas are now slowly starting to outweigh the drawbacks it used to hold back then. Also, it can be seen from the current scenario that the government of India is also keen to take on this new fuel source and implement it as widely as feasible.
