The full form of CNG is Compressed Natural Gas. Diesel, gasoline, and LPG can all be substituted with compressed natural gas (CNG) (liquefied petroleum gas). CNG produces fewer harmful gases when burned than the other fuels discussed above. Compared to other liquids, natural gas poses less of a concern in the event of a leak because it is lighter than air and scatters quickly after being discharged.

Benefits of CNG
- It costs less than alternatives like diesel and petrol, which are used to power buses and other vehicles.
