Fuelling Satisfaction


We at IGL envisage a long lasting friendship between CNG and its consumers. And while every friendship in itself is to be desired, it is said the initial cause of friendship is from its advantages.

Furthermore, when you are apprised of the advantages of using CNG, this friendship is certain to leap from being strong to stronger.

The advantages of using CNG are varied and distinct. The first and most important benefit of using CNG is that you are using a 'green fuel'.

Presented below is an outline of the benefits that CNG offers –

  • Green fuel -
    Commonly referred to as the green fuel because of its lead and sulphur free character, CNG reduces harmful emissions. Being non-corrosive, it enhances the longevity of spark plugs. Due to the absence of any lead or benzene content in CNG, the lead fouling of spark plugs, and lead or benzene pollution are eliminated.

  • Increased life of oils -
    Another practical advantage observed is the increased life of lubricating oils, as CNG does not contaminate and dilute the crankcase oil.

  • Mixes evenly in air -
    Being a gaseous fuel CNG mixes in the air easily and evenly.

  • Safety -
    CNG is less likely to auto-ignite on hot surfaces, since it has a high auto-ignition temperature (540 degrees centigrade) and a narrow range (5%-15%) of inflammability. It means that if CNG concentration in the air is below 5% or above 15%, it will not burn. This high ignition temperature and limited flammability range makes accidental ignition or combustion very unlikely.
