Compressed Natural Gas, in short CNG is nothing but Natural gas compressed for the use of transport sector. Due to its low density, it is compressed to a pressure of 200-250 kg/sq. cm to enhance the vehicle on-board storage capacity. Principal constituents of natural gas are Methane and Ethane, but most gases contain varying amounts of heavier hydrocarbons that are normally removed by processing. After recovery of the heavier hydrocarbons, the remaining gas, known as lean gas, is returned to the pipeline system. Natural gas is drawn from pipeline system for compression and distribution as CNG. Predominantly Methane is available in the lean gas, hence CNG contains mostly methane (normally not less than 85%).

Mainly consists of methane (92-93%), with other constituents like ethane, propane and butane.

CNG stands for Compressed Natural Gas.
Natural gas is compressed to a pressure of 200-250 kg/cm (to be stored in a cylinder) and hence the name Compressed Natural Gas.
It mainly consists of methane (91.9%), with other constituents like ethane, propane and butane.
Uses/Advantages:
It is an intrinsically pure fuel that emits negligible quantities of pollutants when burnt.
It is colorless, odourless, non-toxic, non-carcinogenic and lighter than air.
It is 130 octane (lighter than 93 octane for petrol), hence a CNG vehicle is more energy efficient.
It allows the use of the catalytic converter more easily than diesel.
It is lead-free.
