What is CNG
CNG is the compressed form of Natural Gas,
which is mainly composed of methane [CH4]), which is less than 1% of the volume it occupies at standard atmospheric pressure
so that large volume of gas can be stored in CNG cylinder. Final filling pressure of CNG in the vehicle cylinder is limited to 200 bar.
CNG is successfully used as a fuel in our transport system from Decades, more popularly termed as "Green Fuel". CNG is widely used in Auto rickshaws, Cars & Buses. For use in Automobiles as fuel, it is compressed to a pressure of 200-250 bar to enhance the vehicle on-board storage capacity.
CNG or Compressed Natural Gas is a fossil fuel substitute for petrol, diesel, or LPG. CNG is more environmentally clean alternative to those fuels, and it is much safer than other fuels in the event of a spill.
