Lower Emission in a CNG-powered car,it has been found that Pollution levels of carbon Monoxide (CO) and hydrocarbons (HC) fall By 97 percent and 11 percent respectively

Low Cost CNG fuel costs almost 30 percent less than petrol ,with 1kg of CNG producing energy equivalent to 1.3 litres of petrol

Safety since CNG is lighter than air ,it dissipates quickly into the Atmosphere rather than forming hazardous pools, as liquid fuels do. Also ,CNG ignites at much higher tempreture than gasoline ,making Inadvertent ignition less likely .The CNG cylinders are made from ½” to ¾” aluminium or steel and are much safer thanConventional petrol tanks,which are made of thin sheet metal.

Fuel economy CNG has been found to yield a five percent improvement in fuel economy,as compared to petrol,resulting in lower fuel costs and reduction in toxic emissions.

Lower maintenance cost As CNG burns very cleanly,spark plugs and lubricants require fewer changes and tune-ups aren’t needed as often.Engines burning CNG will last two to three times longer than those using petrol.Also,since CNG does not contain any lead,spark plug fouling is compietely eliminated.
