Bharat Stage 'BS' Emission Norms Explained, What does it mean and how does it Impact
Bharat Stage Emission
The standards, based on
European regulations were first introduced in 2000. Progressively stringent
norms have been rolled out since then. All new vehicles manufactured after the
implementation of the norms have to be compliant with the regulations.Since
October 2010, Bharat Stage (BS) III norms have been enforced across the
country. In 13 major cities, Bharat Stage IV emission norms have been in place
since April 2010 and It's enforced for whole country from April 2017. In
2016, the Indian government announced that the country would skip the BS-V
norms altogether and adopt BS-VI norms by 2020.
The phasing out of
2-stroke engine for two wheelers, the cessation of production of Maruti 800
& introduction of electronic controls have been due to the regulations related
to vehicular emissions.
While the norms help in
bringing down pollution levels, it invariably results in increased vehicle cost
due to the improved technology & higher fuel prices. However, this increase
in private cost is offset by savings in health costs for the public, as there
is lesser amount of disease causing particulate matter and pollution in the
air. Exposure to air pollution can lead to respiratory and cardiovascular
diseases, which is estimated to be the cause for 6.2 lakh early deaths in 2010,
and the health cost of air pollution in India has been assessed at 3% of its
GDP.

In order to comply with the BS-IV
norms, 2- and 3-wheeler manufacturers will have to fit an evaporative emission
control unit, which should lower the amount of fuel that is evaporated when the
motorcycle is parked.

The above standards apply to all new
4-wheel vehicles sold and registered in the respective regions. In addition,
the National Auto Fuel Policy introduces certain emission requirements for
interstate buses with routes originating or terminating in Delhi or the other
10 cities.
Trucks and buses:-
Exhaust gases from
vehicles form a significant portion of air pollution which is harmful to human
health and the environment

Overview
of the emission norms in India
·
1991 – Idle CO Limits for Petrol Vehicles and Free Acceleration
Smoke for Diesel Vehicles, Mass Emission Norms for Petrol Vehicles.
·
1992 – Mass Emission Norms for Diesel Vehicles.
·
1996 – Revision of Mass Emission Norms for Petrol and Diesel
Vehicles, mandatory fitment of Catalytic Converter for Cars in Metros on
Unleaded Petrol.
·
1998 – Cold Start Norms Introduced.
·
2000 – India 2000 (Equivalent to Euro I) Norms, Modified IDC
(Indian Driving Cycle), Bharat Stage II Norms for Delhi.
·
2001 – Bharat Stage II (Equivalent to Euro II) Norms for All
Metros, Emission Norms for CNG & LPG Vehicles.
·
2003 – Bharat Stage II (Equivalent to Euro II) Norms for 13
major cities.
·
2005 – From 1 April Bharat Stage III (Equivalent to Euro III)
Norms for 13 major cities.
·
2010 – Bharat Stage III Emission Norms for 2-wheelers,
3-wheelers and 4-wheelers for entire country whereas Bharat Stage – IV
(Equivalent to Euro IV) for 13 major cities for only 4-wheelers. Bharat Stage
IV also has norms on OBD (similar to Euro III but diluted)
·
2020 – Proposed date for country to adopt Bharat Stage VI norms
for cars, skipping Bharat Stage V
What should be
expected in the future?
As of now, BS IV
will be implemented from April 1, 2017. Those looking to purchase a vehicle
will have to spend a higher amount than before to own one.
But, the larger
aim for the automotive sector as a whole is to implement BS VI emission
regulation by the year 2020 in I
To sum it up,
India is making an effort to reach the global standia. Yes, BS VI and yes, BS V will be skipped.
This will require a huge amount of investments to make the oil refineries capable of producing a better quality of fuel and also investments in the infrastructure to make that fuel available across the country.
Then, the automakers will have to make investments on their end too in order to speed up the research and development process and improve their own infrastructure – like the manufacturing plants – to make their offering BS VI compliant.
This, eventually, will make owning an internal combustion engine powered car more expensive to own, and maintain.ndards and hence, a lot of
changes in the trends, sales and choices made by customers are expected in the
coming years.
Nice blog and helping.😊👌
