BS4




The BS4 policy was made mandatory across the country in April 2017. Pollutant carbon monoxide emissions from petrol-powered passenger vehicles were limited to 1.0 g / km, hydrocarbon + nitrogen oxide emissions to 0.18 g / km, and responsive suspended particulate matter 0.025. Diesel models emitted carbon monoxide at 0.50 g / km peak, 0.25 g / km nitrous oxide and hydrocarbon + nitrogen oxide 0.30 g / km. Also, the sulfur content in BS4-approved fuels was limited to 50 ppm.
To convert engines compatible with BS3 to BS4 units, manufacturers have added larger catalytic converters to reduce nitrogen-based emissions. Meanwhile, manufacturers have tweeted to the ECU to ensure more efficient combustion. The BS4 motor also received modified air intake and exhaust systems.
