What is the full form of CNG ?

Compressed Natural Gas

CNG is a compressed natural gas. CNG burns most efficiently, unlike petrol or diesel, in the automobiles and very little of it is left unburnt.

Moreover, CNG is cheaper than petrol or diesel, cannot be siphoned off by thieves and adulterated like petrol or diesel.

The main problem with switching over to CNG is the difficulty of laying down pipelines to deliver CNG through distribution points/ pumps and ensuring uninterrupted supply.
