Environmental pollution has proven to be a big threat to our eco-system and pollution from automobiles using conventional fuels is a major contributor to this. Alternative fuels are the only immediate option that can help us counter the ever rising environmental pollution. In today’s date we cannot directly replace an IC engine, so the most efficient option available is using a fuel that can work with the IC engines other than gasoline and diesel. CNG proves to be the most promising fuel. A diesel engine converted to stoichiometric CNG engine was used for optimization. The paper deals with the improvement of engine power from 50HP to 60HP and up-gradation of the emission from BS-III to BS-IV norms of a multi-cylinder naturally aspirated engine. This was achieved by varying the compression ratio, valve-lift profile, intake plenum volume, runner length, spark-advance timing, fuel injection location, exhaust pipe length and catalytic converter selection.
