how the cng is fitted in diesel engin till now i have

Rohit

There are'nt any cng kits available for diesel engines as yet with no possibility even in the near future.For average let's say u have a petrol swift and you fit cng in it,it will give you about 18kms/kg of cng and cng costs about 22 rupees per kg.Whereas a diesel swift will give about 17 kmpl and diesel costs about 34 rupees a litre.People may claim that the swift diesel gives 20 kmpl but it's baseless and u can safely expect about 16-17 kmpl from a diesel swift.So if it's economy that u want the petrol/cng swift wins hands down..You lose all your boot space though
