What Is CNG, And What Are Its Advantages?


CNG As An Alternative Fuel:

CNG stands for Compressed Natural Gas. It is an alternative fuel to Petrol, Diesel & LPG. However, it is safer to use, cleaner to burn, and produces less harmful by-products than petrol, diesel & LPG. In addition, it is lighter than air. So, unlike the LPG, it can rise in the air & escape quickly in the case of leakage. Thus, this gas poses no danger to the car or its occupants whatsoever.

It can disperse quickly in case of spillage. As the name suggests, the companies produce CNG by compressing the natural gas, mainly methane.

Advantages As Fuel:

The compressed natural gas does not contain any lead, thereby eliminating the fouling of spark plugs. Furthermore, the maintenance cost of CNG-powered vehicles is lower than that of Diesel-powered cars while it is almost in line or slightly higher than that of Petrol cars. Besides, the manufacturers offer CNG fuel systems in sealed condition. Thus, it prevents fuel losses from spills or evaporation.

Compressed Natural Gas or CNG increases the life of lubricating oils as it does not contaminate and dilute the crankcase oil. It mixes quickly and evenly with the air and burns cleaner as a gaseous fuel. Besides, it is a cheaper option than conventional fuels such as Petrol and Diesel. Thus, CNG-powered vehicles are comparatively more affordable to buy and operate. Therefore, it brings significant savings to the buyer/operator who uses a CNG-powered vehicle in the long run. Hence, many small pick-up trucks up to the capacity of 1 ton prefer to buy CNG-powered vehicles for daily use.

Shell, BP, and Natrugy, formerly known as Gas Natural Fenosa, Mahanagar, and Gas Energy Australia, are some of the Compressed Natural Gas manufacturers around the world.
