Under the Bharat Stage-II, the maximum permissible sulphur content in fuels was restricted to 500 PPM. In terms of emissions, acceptable Carbon Monoxide emissions were 2.2 g/km, respirable suspended particulate matter discharge was 0.08, and 0.05 g/km was the maximum discharge limit for Nitrogen Oxides and Hydro Carbons. Instead of the carburettor, car makers had to equip the automobiles with a Multi-point Fuel injection system.
