BS6 In India




BS-VI Intro (25-07-18)

With India’s growing concern for pollution, the government is taking  bold steps to control  pollution levels. On February 19, 2016, the Indian Ministry of Road Transport and Highways (MoRTH) issued a draft notification of Bharat Stage (BS) VI emission standards for all major categories of on- road vehicle  in India. This decision came after a through analysis of current indian emission standards. The Indian emission standards are based on European Emission Norms. While European countries are way ahead in terms of emission norms and standards implementation, the same is being implemented in India after 5 years of gap in urban cities and almost after 10 years nationwide. This huge gap in implementation of emission norms results in technological backwardness in Indian automotive sector.


BS-VI Implementation (27-07-18)

The decision to skip the BS-V emission norms is to bring the Indian emission norms in synch with the more robust international emission norms. The BS6 emission norms will come into effect on 1 April 2020 or later. The BS6 Norms makes it mandatory to all vehicles to have an OBD port irrespective of make and model, including 2 wheelers. In addition, harmful exhaust gases such as nitrogen oxides (NOX), carbon monoxide (CO), and hydrocarbon (HC) are further reduced by almost 25%.


Testing under BS-VI Norms

One of the important aspect of BS6 is the vehicle emission test  for LMV. The test will be conducted on “Real-World Driving Cycle Test”  using a Portable Emission Measurement System (PEMS) and for HMV, the World Harmonized Steady-State Cycle (WHSC) and World Harmonized Transient Cycle (WHTC) will be implemented which are more real world driving based. This will help to replicate the lab emission standards in the real world driving cycle.
