CNG 1

Till the late Nineteenth Century, automobiles were fuelled with conventional types of fossil fuel namely Petrol and Diesel all across the globe and India is no different. 

However, beginning 1990s as the Indian economy started opening to the rest of the world and by 1995’s the Indian population counted close to 97.00 Cr. So, several international automobile manufacturers found it an opportune moment to enter the Indian market and reap a rich harvest.

Within a few years, several international automobile manufacturers started either assembling their automobiles in India or started manufacturing through “Joint ventures”. As a result, within 2000, there is a phenomenal growth in the automobile sector and soon Indian roads were crowded with automobiles as never before. This ultimately caused deterioration of ambient air quality to its worst, highly poisonous and toxic.

Then the Hon’ble Supreme Court intervened followed by the GOI constituted “Environment Pollution and Controlling Authority-EPCA” and the implementation of CNG started in India from 1999-2000. This begins with the retro fitment of petrol autorickshaws to CNG in Delhi, then conversion of DTC buses followed by all private buses plying within the Delhi NCTR region.

The CNG cylinder, Valve & its re-testing is governed through Gas Cylinder Rules-2016 under Indian Explosives Act-1884. While CNG cylinder and its valve manufactured as per IS-15490 and IS-3224-2009 and cylinder retesting is done as per IS-8451 respectively.

Final Thoughts

To comply with the order of the Hon’ble Supreme Court, soon lacs of automobiles converted from petrol & diesel to CNG run vehicles. Subsequently, Millions of OEM CNG vehicles were also added to Indian roads. No doubt, the CNG implementation in India proved to be of a great success worldwide. Though the CNG implementation in India found to be a great success,  but as long as CNG cylinder re-testing is concerns, much more needed to be done to ensure “Zero Error”, “Zero Incident”,  “Zero Compromise” policies of the CCOE-PESO. Presently it is at its lowest ebb.
