The Society of Indian Automobile Manufacturers (SIAM) is gearing up to progress to Bharat Stage (BS) V emission norms, that will come into effect from 2019 onwards. The move has been welcomed by the body.
Commenting on the progression, Vinod Dasari, the President of SIAM, said, "Upgradation to BS V norms would reduce the pollution levels from the 4-wheeler industry by 80 percent in terms of PM 2.5 for HCV and 90 percent for passenger cars and NOx will be reduced by 60 percent and 64 percent respectively.
"This will make huge contributions to the ambient air quality of Indian cities. We are happy that SIAM's recommendation to advance the BS V timeline to 2019 has been accepted by the Government."
But before the technology can be made for public use, the requisite 10 PPM sulphur BS V fuel will have to be introduced by the oil companies by 2019 across India. If the needed fuel is unavailable, the usage of BS IV fuel might damage the engine as well as the after-treatment devices fitted in the new vehicle. Also, the required emission norms cannot be met.
SIAM has proposed that the BS VI norms can be advanced to 2023, since advancement of BS VI norms will neither be technically possible or advisable. Even technology providers will be unable to provide the required validated BS VI solutions before 2023.
