CNG stands for Compressed Natural Gas and is used as an alternate fuel option for automobiles. It is gaseous fuel and is a mixture of hydrocarbons, mainly methane, in the range of 89% to 90%. Due to its low density, it is compressed to a pressure of 200-250 kg/cm² (g) to enhance the vehicle onboard storage capacity.


 No impurities, No Sulphur (S), No lead (Pb).

 Very low levels of polluting gaseous emissions without smell and dust.

 Lighter than air - in case of leak no dangerous fire accidents.

 CNG cylinders are structurally most sound and have passed every severe test.

 Cheaper than conventional fuel: Payback period is short (around 3 - 4 Years)

 Unlikely to ignite due to:

High ignition temperature

The narrow range of ignition

Lowest injury and death rate per vehicle mile for CNG cylinder.
