2. The major difference in standards between the existing BS-IV and new BS-VI auto fuel norms is presence of sulphur.
Which of the statements are correct?
The correct option is C c) Both 1 and 2
Delhi became the first city in India to supply ultra-clean Bharat Stage (BS) VI grade fuel (both petrol and diesel) with an aim to combat the rising levels of air pollution in Delhi-NCR region. State-owned oil firms have started supplying the BS-VI fuel (equivalent to fuel meeting Euro-VI emission norm) at all their 391 petrol pumps in NCT.
The major difference in standards between the existing BS-IV and new BS-VI auto fuel norms is presence of sulphur.
BS-IV fuels contain 50 parts per million (ppm) sulphur, while BS-V and BS-VI grade fuel will have 10 ppm sulphur. Thus, newly introduced BS VI fuel is estimated to reduce amount of sulphur released by 80%. It will also bring down the emission of NOx (nitrogen oxides) from diesel cars by nearly 70 % and 25% from cars with petrol engines. It will also bring down cancer causing particulate matter emissions from diesel engine cars by phenomenal 80%.
